DYNAMICS AND STRUCTURE OF THE COMPOSITE FILMS OF FLUORINATED POLYMERS AND IONIC LIQUIDS
¿Smart¿ electroactive composite polymeric materials attract wide attention due to their ability to respond to external stimuli in a controllable manner. A novel nanoparticle-free approach consists of using ionic liquids (ILs) instead of common fillers (nanoparticles, carbon-based materials, etc.) A practically important relation of the macroscopic properties of these new polymer/IL composites to the mobility and structural organisation of the ILs is not understood. The aim of the experiment is to investigate the dynamics and nanostructure of two ILs in matrices of an electroactive copolymer - poly(vinylidenefluoride-co-trifluoroethylene). We plan to follow the self-H-dynamics of the IL cations in composite materials with different structure by WASP. We will vary the interaction between IL and polymer by using two ILs and polymer matrices differing in polarity and crystalline structure. We will correlate the observed dynamics with nanostructure by employing SANS at D22 spectrometer. Our preliminary WASP experiments show that the dynamics of IL is different in confinement (within the composite) and in the bulk, which is due to specific interactions between the components.
