Polysulfone as a material for advanced electrical batteries
The materials based on polysyphone are used for polymer electrolite production. The rheological properties were measured for three component system polysulphone - solvent - propylene carbonate. The varying factor was propylene carbonate used as a plasticizer for polysulphone. Experiments were carried out in a wide shear rate and frequency ranges at 25 ºC. Polymer was characterized by the IR-spectral method. Rheological experiments were carried out using the technique of rotational rheometry. It was shown that the rheological behavior of all samples is linear and these three-component systems are viscoelastic liquids. It can be assumed that all systems under study at homogeneous in the absence of traces of water. The final goal of the study was the choice of the optimal composition (concentrations of a solvent and plasticizer) and the regime of preparing thin films from these systems which could provide obtaining solid state electrolyte for creating advanced electrical accumulator with a none-fragile polysulfone membrane. This part of the research is devoted to investigation of the rheological properties (viscosity and viscoelastic properties of composition of polysulfone - solvent - propylene carbonate systems.
