Polysiloxane-Based Polymer-Electrolyte Complexes Johannes Smid, Daryle Fish, Ishrat M. Khan, Ε Wu, and Guangbin Zhou Polymer Research Institute, College of Environmental Science and Forestry, State University of New York, Syracuse, NY 13210 Comblike polysiloxanes with oligooxyethylene side chains were syn thesized from poly(hydrogen methylsiloxane), and the conductivities and thermal properties of their solvent-free LiClO complexes were measured. The side chains were of the type -O(CH CH O) CH (PMMS-8), -(CH ) O(CH CH O) CH (PAGS polymers with n = 7 or 11), and -(CH ) OCH CH(OH)CH SO -Na (PAGSO -Na ). Cloud points were determined in water for PMMS-8 in the presence of various salts. Maximum conductivities of the LiClO complexes with PMMS-8 and PAGS polymers reached values close to 10 /Ω -cm at 25 °C, and ratios of ethylene oxide units to Li were between 20 and 25. Mechanical properties were improved by cross-linking or by blending with high-molecular-weight poly(ethylene oxide). The conductivity of the cation conductor PAGSO -Na at 75 °C was
