Abstract:

Following the European policies on risk management in emergency situations, security systems and human health protection, it can be acknowledged the importance of the detection subsystem (that covers the protection against pollutants).

Since the sensing mechanism used by the gas sensors is based on a surface reaction and a high surface-to-volume ratio, it is unanimously accepted that the electrospun nanofibres, which are characterized by a specific surface area of about one to two orders of magnitude greater than the flat films, are exceptional candidates for applications in sensors.

Electrospun nanofibers can be easily molded into microelectrodes, which show a significantly better response to various gases than conventional films.

The operator holds the technology and the computer multijet needle electrospinning equipment. The operator needs to increase the production of electrospun nanofibers, a current goal in the international research, which is stipulated in the project through the assimilation / development / optimization of the electrospinning technology with debiting mechanism (jet and multi-jet) with interchangeable punctured electrodes (fixed / mobile) to obtain 3D structures for security applications.

In order to obtain bigger absorption, specific morphological characteristics are required and this is why the 3D nanostructures obtained by electrospinning are suitable for gas detection applications due to their multiple well-known advantages.

Replacing the needle mechanism with a interchangeable punctured electrodes mechanism ensures increased production of electrospun nanofibres and the possibility of obtaining 3D nanostructures capable of identifying harmful compounds (acid/alkali) in the environment; this constructive change of the debtor mechanism requires tests /analyzes/experiments/validations/ optimization obtained by the expertise of the university research team.

Abstract:

Electrostatic discharge (ESD) and electromagnetic compatibility (EMC) for protection products will boost in the next 5 to 10 years in order to overcome the vulnerability of electronic devices to static electricity and electromagnetic inference at high frequencies. As the semiconductor industry will increase protection for on-chip and in-fab applications and post-fab handling and preservation of micro-electronic products, the demand of ESD/EMC garments is expected to attain a turnover of US $480 million by 2015. Presently, the ESD garments are realized as conductive composite textiles by combining conventional textile fibres with conductive ones and/or by surface treatment with hygroscopic agents to endow good conductive properties. The manufacturing technology is similar to the one used for standard clothing. Within the present proposal new ESD garments concept and manufacturing technology are proposed, making use of a single structure (integral) knitting of core conductive fibres. The integral knitting will assure an intrinsic electrical continuity within the whole garment. The functionalization of the new structure will be realized: (1) at macrostructure level, the fibre’s continuity being ensured by the integral knitting technology, with high ESD effects, (2) at microstructural level by use of different conducting fillers structures. The research methodology for developing the final structure is encompassing specialised electromagnetic simulation of conductive fibres in predefined spatial architectures, ESD/EMC measurements, textile technology design and testing for integral knitting. In terms of economic benefits, the potential impact will be the development of a versatile technology and also of a product with flexible tailored features for intersectorial markets, general EMC/ESD knowledge expanding, technology transfer plan for the involved industrial partners with an envisaged increase of employment and turnover.
