Synthesis of organic-inorganic polymer hybrids having interpenetrating polymer network structure by formation of ruthenium-bipyridyl complex

摘要

Organic-inorganic polymer hybrids were prepared by an in-situ method. In the presence of ruthenium salt, the cross-linking reaction of bipyridyl-containing polymer was carried out together with the sol-gel reaction of tetramethoxysilane. This methodology includes the simultaneous formation of silica gel and organic gel. Using polystyrene or poly(ethylene oxide) having bipyridyl groups, organic-inorganic polymer hybrids could be prepared. The obtained polymer hybrids having IPN (interpenetrating polymer network) structure showed excellent solvent-resistant property. [References: 24]
