Hybrid Inorganic-organic Polymer Electrolyte Membranes (PEMS) Based On Alkyloxysilane Grafted Thermoplastic Polymers

Abstract

A composition of matter is formed from a graftable polymer, having graftable sites onto which sidechains have been grafted. The sidechains include at least one silane group, and may be formed by polymerization of a polymerizable group of a silane precursor. These compositions may further include acid groups, and may be used, for example, in improved proton conducting materials in fuel cells.
