Fluorine-Containing Siloxane Based Polymer Electrolyte Membranes
The hydrosilylation reaction of 2,4,6,8tetrahydro-2,4,6,8-tetramethylcyclotetrasiloxane (D4) with 2,2,3,3-tetrafluoropropyl acrylate and vinyltriethoxysilane in the presence of platinum catalysts (platinum hydrochloric acid, Karstedt’s catalysts and Pt/C (10%) at 323 K) has been carried out and corresponding addition adduct (D4) has been obtained. The synthesized product D4 was analyzed by FT-IR, H, C, and Si NMR spectroscopy. Sol-gel reactions of D4 doped with lithium trifluoromethylsulfonate (triflate) have been studied and solid polymer electrolyte membranes have been obtained. Electric conductivity of solid polymer electrolyte membranes has been determined via electrical impedance spectroscopy.
