Thermal and solvent-resistant properties of organic-inorganic polymer hybrids having interpenetrating polymer network structure by formation of metal-bipyridyl complex

Abstract

Organic-inorganic polymer hybrids having IPN (Interpenetrating Polymer Network) structure were synthesized utilizing an in-situ method, which was the simultaneous formation of organic gel through metal-bipyridyl complex and silica gel. Metal-bipyridyl complex was used as a cross-linking point to prepare the organic gel. The properties of the polymer hybrids, such as solvent-resistant and thermal properties, were different according to the kinds and the weight of the used metal ions. Especially, thermo-responsive polymer hybrids could be obtained using iron (II)-bipyridyl complex as a cross-linking point in the silica matrix.
