Abstract
The paper is devoted to the sol-gel synthesis of proton conductive organic-silicon composite membranes based on tetraethyl orthosilicate (TEOS) and copolymers of 2-methyl-5-vinylpyridine and vinyl chloride (MVP-VC), 2-methyl-5-vinylpyridine and vinyl acetate (MVP-VA), copolymers of ethylene glycol vinyl glycidyl ether and styrene (KS-1 and KS-2), and nitrogen-containing heteroaromatic derivatives of sulfonic acids: 2-phenyl-5-benzimidazolsulfonic acid (PBISA) and pyridine-3-sulfonic acid (PSA). Properties of synthesized membranes, such as proton conductivity, activation energy, ion exchange capacity, dimensional stability have been investigated.
