Phenylvinyl polysiloxane (PVPS) electrolytes with various phenyl derivatives has been successfully achieved. The phenyl derivatives used in phenylvinyl polysiloxane electrolytes are phenyl and mesityl group. Thermally stable transparent PVPS electrolytes with high refractive index was synthesized by the thermal curing reaction of phenylvinyl oligosiloxanes (PVOS). PVOS was obtained by a sol-gel condensation process between vinyltrimethoxysilane (VTMS) and diphenylsilanediol (DPSD). We have investigated the effect of phenyl derivatives on PVOS electrolytes. Instead of using DPSD, dimestylsilanediol (DMSD) was used for the synthesis of mesitylvinyl oligosiloxane (MVOS). DMSD was synthesized from the reaction of 2 equivalents of mesityllithium and silicon tetrachloride. To obtain mesitylvinyl polysiloxane (MVPS) electrolytes, MVOS was thermally cured at 150 ℃ for 3 hours. The comparison with DPSD was achieved. The physical properties such as an optical transmittance, refractive index, and harness were measured. This research was financially supported by the Ministry of Trade, Industry, and Energy (MOTIE), Korea, under the “Regional Specialized Industry Development Program” supervised by the Korea Institute for Advancement of Technology (KIAT).
