Özet
A series of comb-like polysiloxanes was prepared as the base polymer for solvent-free polymer electrolyte membranes. Hydrosilylation of poly(methylhy-drosiloxane) (PMHS) was used to substitute hydrogen by the two types of side groups tetraethylene glycol allyl methyl ether and allyltrimethoxysilane (ATMS) with varying molar ratios between 5 and 40 mol-% ATMS. The ATMS side groups served to cross-link as-prepared polymer electrolyte membranes after dissolving lithium trifluoromethylsulfo-nate (triflate) or lithium bis(trifluoramethylsulfonyl)imide. The ionic conductivities of these salt-in-polymer membranes prepared with a constant concentration of 10 wt.-% lithium triflate showed a maximum conductivity of 4.6 × 10-5 S · cm-1 at 30°C for 10 mol-% ATMS substitution. In another series of experiments with the ATMS substitution held constant at 10 mol-%, the salt concentration was varied yielding a maximum conductivity of 1.4 × 10-4 S · cm-1 at 30°C for 12.5 wt.-% lithium triflate. © 2006 WILEY-VCH Verlag GmbH & Co.
