UV curable cross-linked polymer and polymer-inorganic materials for fuel cell application

Abstract

Proton conductive cross-linked membranes (polyacrylate copolymer and polyacrylate-silica nanocomposites) were synthesized by UV initiated polymerization in situ. Proton conductivity of membranes, investigated by impedance spectrometry, was found to be sufficiently high. Contact angle measurements allow to estimate free surface energy of synthesized membranes. The membranes also exhibit good thermal stability.
