Abstract:

Electromagnetic pollution has launched an increase in research into possible consequences and remedies, to identify and produce new electromagnetic shielding materials. The idea of the proposal appears in response to the need to find and develop new composite structures that improve the functioning of electronic equipment, eliminating interference and reducing the level of radiation, through absorption. While military electronics used to operate in a narrow band of frequencies, today military design engineers must protect equipment against interference and detection at a much wider range of frequencies, up to 95 GHz! The incidence of occupational diseases is high in the case of personnel working near high-power radars, hence the need to develop highly efficient materials for absorbing microwaves. Starting from TRL2, the project proposes the design, development (TRL3) and laboratory-scale validation (TRL4) of a demonstration model of composite structures usable as microwave absorbers, with heat dissipation properties, based on ferromagnetic nanoparticles fixed on a grid of reduced graphene oxide-carbon nanotubes-polymer. The project aims to, after the completion of the proposed activities, develop these materials up to higher TRLs and establish a transferable production technology to the industrial partner, ROSEAL.

Abstract:

The aim of the project is to obtain and to demonstrate the functionality of an innovative conductive composite material having a positive temperature coefficient (PTC) effect, recently developed as an optimized experimental model within the ICPE-CA and the exploitation of the results obtained so far by developing a model with direct practical applicability, with the prospect of being introduced into manufacture, namely a heating cable with self-regulating temperature properties. The key element of the proposed cable is the mentioned conductive composite material that produces heat through the Joule effect and is able to self-regulate its temperature by electric percolation-depercolation effects at a certain temperature specific to the respective material. Such a cable can be integrated into interior (floor) or exterior (paving, roof) construction elements to ensure a certain constant ambient temperature of the house and to prevent the formation of ice, respectively. Therefore, within the project it is proposed the experimental realization, based on a laboratory technology, of a heating cable model with self-regulating temperature effect and testing of its functional characteristics. The results will be useful for demonstrating the functionality of the model and will allow the transition to a higher stage in results exploitation by their transfer to a manufacturer.

Abstract:

With the accelerated progress of science and technology from the last decades, more and more electrical equipments and information systems have been used in different domains. However, such equipments and systems cause electromagnetic radiation that is harmful to the health and affects the normal working of electronic equipments, through interferences. The idea of the proposed project occurs as answer to the necessity to identify and develop new composite structures that allow the reduction, by absorption, of the radiation level and improve the operating, by eliminating interference. The microwave absorbing materials plays an increasing significant role in national defence security, health, electronics reliability.

It is well known that the incidence of professional diseases in the case of the personnel operating near the powerful radars is highly increased, hence the need to identify and develop highly efficient microwave absorbing materials, especially for the specific radar radiations, around the frequency of 3 GHz.

The project aims and proposes to design (TRL 2), develop (TRL 3) and validate at the laboratory scale (TRL 4) a demonstration model of hybrid structures, based on ferromagnetic grafted graphene derivatives, produced by chemical synthesis, with the aim to be used as microwave absorbers.

The project aims also, at the end of proposed activities, to develop in the future projects these hybrid structures, up to higher TRLs, and to set-up a technology for production of these new functional mats, adequate for a future technological transfer to the industrial partner, ROSEAL company.

Abstract:

Reducing electromagnetic interference over a broad band of radio frequencies is crucial to eliminate the adverse effects of the increasingly complex electromagnetic environment. Current shielding materials or methods suffer from tradeoffs between optical transmittance and EMI shielding capability. Moreover, poor mechanical flexibility and manufacturing complexity significantly limit their additional applications in flexible electronic devices. In this project a technology will be developed to manufacture transparent conductive thin layer structures with thicknesses of max. 600 nm, with a surface resistance of max. 100 ohms / square for a shielding efficiency of at least 25 dB and for anti-static effect with a surface resistance of maximum 1000 ohms / square, on flexible and rigid transverse substrates for transmissions in visible of at least 80%. Transparent EMI shielding components will be made and tested. The thin layers of electromagnetic protection will be made in the form of a suitable design (eg conductive-dielectric-metal-dielectric) to improve the electro-optical compromises, to obtain a transmittance in the visible spectrum of at least 80% in relation to the substrate and an excellent efficiency. of shielding effect (SE-shielding effectivnes)> 25 dB, over a broadband bandwidth of up to 30 GHz, covering all bands X, Ku, Ka and K. An efficiency of EMI shielding> 30 dB is estimated to be achieved by the overlap of at least two transparent conductive thin layers and could be further improved up to 50 dB by separating two layers with a quarter-wavelength space. High-performance flexible or rigid substrate thin-layer structures have high potential for various applications such as: portable electronics, medical devices and electronic safety zones.

Abstract:

The large concern of global energy challenges has greatly increased the interest and investments in renewable and clean energy that can replace fossil fuel. Among all known systems to generate energy, solar power is the most promising one. Hence, no one doubts the important role that photovoltaics (PV) are going to play in the energy of the future. The main drawbacks of the current PV technologies are their high production cost and rigid structure in the case of traditional silicon and inorganic semiconductors, or their reduced efficiency and durability in the case of organic and DSSC photovoltaics. One of the bottlenecks of increasing the conversion efficiency in DSSC is the transport of photogenerated electrons. The general approach to surpass these limitations is employing one of the following strategies: doping, growing vertically oriented porous structures on top of the conducting substrate, interconnecting TiO2 nanoparticles with charge carriers to direct the photogenerated current or find alternative materials with higher electronic mobility. Due to the richness of its optical and electronic properties, 3D graphene is the material of choice for our proposed studies. The ability to develop free-standing 3D graphene structures with large specific surface area will enable the successful realization of fast transport channels of charge carriers, thus leading to high electrical conductivity. Moreover, by combining their good electrical conductivity with their porous structure, the 3D graphene structures will increase the photocurrent density of DSSC by enhancing light absorption (sensitizer loading), enabling efficient charge separation and light scattering. In this context, the general objective of the project is: to evaluate the functionality of the 3D graphene structures in optoelectronic devices, specifically in photovoltaic cells (DSSC).

Abstract:

An important role in sustainable development and energy efficiency of buildings have building materials. European directives related strategies include building energy efficiency, durability and functionality of the materials used in residential and industrial buildings.

The use and development of new construction materials aims to improve the energy efficiency of buildings and at the same time, producing environmental and life quality improvements. The choice of materials for use in masonry and plaster work, is done according to the structure of the building, heating needs, the condition of buildings, the quality of the construction materials.

Building insulation is very important in reducing energy losses in noise reduction and at the same time to achieve a thermal and aesthetics comfort.

In this context, it is proposed the development of mortar systems based composite microspheres used in masonry and development of composite materials with microspheres (plaster) used in the building envelope and protection. These materials will provide high thermoinsulation by the heat reflecting properties, simultaneously with a good sound insulation of building. This will make composite mortar materials for plastering containing added inorganic mircosfere with micro-and nanostructured cavity closed and vacuumed pores (to provide enhanced thermal insulation by "thermos" effect and sound vibrations reduction).

Composite materials systems will have the following properties: low thermal conductivity (at least 10 times less than the usual materials known), a high resistance to ultraviolet and infrared radiations as well as sound absorbing.

To achieve the main objectives, the project will focus on two lines of research:

- development of inorganic hollow micro and nanospheres with closed and vacuumed pores (to provide enhanced thermal insulation by "thermos" effect) which generates multiple materials physicochemical properties: having a low thermal conductivity (0.1-0.5 W/m/oK) reduces energy transfer, reduces (35-85% UV) action and protects against sound vibrations;

- achieving masonry mortars and plastering mortar containing added inorganic microspheres and nanospheres used in building envelope to improve indoor microclimate and reduce energy consumption.

For achieving and testing innovative proposed materials provides:

- selection, synthesis and complex characterization of materials used for the microspheres and composite systems mortars and plasters;

- establishment and characterization of the addition of microspheres and nanospheres with thermo insulating role cavity;

- establishing the structure/composition of the composite systems to ensure appropriate set of properties;

- development of protecting composite mortars and plasters and their characterization (compressive strength, adherence to the substrate, the thermal conductivity, the absorbing character for the sound radiation);

All of the above are expected to be achieved by the experimental model, functional model, the development of technical specifications for each material made.

It also, dissemination of the results by publishing the articles in professional journals and attending scientific meetings.

Abstract:

Graphene-based polymer nanocomposites (GBPNC) share common features with regard to fabrication methodologies, processing, morphology characterization and fundamental physics. The key to prepare advanced GBPNC is to control the engineering of the polymer-graphene interface. Graphene have a pronounced tendency to agglomerate, making them very hard to disperse homogenously in polymers, regardless of the production process of the polymer nanocomposites. The prevention of aggregation is essential because most of their unique properties are present just in the pristine form. Because of this, a series of surface modifications of graphene are performed in order to make them suitable for homogenous dispersion in polymers. In this respect, oxidation followed by chemical functionalization will facilitate dispersion and stabilization, thus preventing agglomeration. In general, graphene are functionalized by attaching small molecules or polymers chains to the graphene surface. The chemical functionalization of the graphene surface is considered to be an attractive solution because this approach renders them hydrophilic (instead of hydrophobic). An improvement in its solubility results in better dispersion and processability, enhancing the interaction between the filler and matrix to the interface. The general objective of the project is to produce 2D and 3D structures of graphene based polymer nanocomposites with improved electrical, thermal, optical and mechanical properties by direct laser writing of monomer/graphene composite using a femtosecond IR laser. A technology will be developed based on the monomer/graphene material interaction during the laser action. The monomer will be urethane mono(dimethacrylates) in different combinations with graphene and surface modified graphene. The project bring at least two novelties: The polimer matrix is new in the filed of GBPNC and DLW is a new technological approch to incorporate graphene in a polymer matrix starting from monomers.
