## Abstract A new membrane material has been developed, based on a polysiloxane framework with functional proton conducting groups such as sulfonic acid and heterocyclic groups, e.g., imidazole and benzimidazole, covalently bonded at the siloxane backbone. Sulfonated siloxane based block‐copolymers
Poly(vinyl alcohol)/poly(2-acrylamido-2-methyl-1-propanesulfonic acid (PAMPS)/3-glycidyloxypropyl)trimethoxysilane (PVA/PAMPS/GPTMS) organic/inorganic proton-conducting polymer membranes are prepared by a solution casting method. PAMPS is a polymeric acid commonly used as a primary proton donor, whi
