Nowadays many types of hybrid organic-inorganic materials are developed because of their wide application, in particular as proton conductive membranes in fuel cells. The objective of our study was to prepare organic-inorganic materials with proton conductive properties using sol-gel method of synthesis. Acrylic monomers: acrylonitrile (AN), acrylamide (AAm) and 3-sulpho-propylacrylate potassium salt (SPAK) were chosen to create polymer matrix in the process of UV-curing. Inorganic counterpart was formed as a result of sol-gel process of TEOSbased sol-gel system (SGS) during photo-initiated polymerization in situ. The ratio between monomers was SPAK:AAm:AN = 25,3:58,5:16,2 (wt. %); SG content in feed composition was varied from 10 till 40 wt. %.
