Abstract (English):
The proton-conducting hybrid organo-inorganic composites based on tetraethoxysilane and sulfonated styrene (St) and allyl glycidyl ether (AGE) copolymers, which are characterized by high exchange capacity and specific conductivity, were formed by sol-gel synthesis. The results of a quantum chemical calculation of the geometry of the structure of an organo-inorganic composite (for a model of 78 atoms) allow us to relate the increase in the proton conductivity of hybrid membranes compared to the initial copolymer with the generation of crystallization water and free sulfuric acid during the formation of the composite.
