Synthesis and Characterization of Organic-Inorganic Membranes Containing Sulphogroups

Iryna Yevchuk, Oksana Demchyna, Viktoriya Kochubey, Hanna Romaniuk and Zenoviya Koval

Organic-inorganic materials have been synthesized by photoinitiated copolymerization of monomers: acrylonitrile, acrylamide and 3-sulphopropyl acrylate potassium salt in the presence of sol-gel systems based on tetraethoxysilane. Thermal stability, water uptake and ion-exchange capacity of obtained materials have been determined. Undertaken studies may be used for development of protonconductive membrane for fuel cells.
