Abstract:

This project aims to synthesize and characterize hydrophobically modified and/or fluorescently labeled polymers, in order to apply them in probing the hydrophobic/hydrophilic interface of regular and reverse micelles and to investigate layer-by-layer polymer assemblies. To accomplish this goal the following parameters will be monitored: the alkyl chain length and amount grafted, the fluorophore content and its nature, the polymer molecular weight, the surfactant, pH, ionic strength, the organic solvent and the reverse micelle hydration degree. The techniques involved in this project are: UV spectroscopy, 1H-NMR, 13C-NMR, GPC and capillary electrophoresis, static and dynamic fluorescence, FTIR, rheometry, DLS, surface tension, goniometry. The acquired data will shed light and elucidate phenomena involved at nanometric scale in these systems. The importance of this study resides in obtaining new intelligent materials able to modify their molecular architecture in response to external stimuli. A particular attention will be payed to fluorescence resonance energy transfer (FRET) for getting insights into the interface of micellar nanocages and of thin films.
