HYBRID MATERIALS BASED ON METAL-OXIDES AND POLY(ORGANOPHOSPHAZENES)

In this paper the set-gel preparation of hybrid materials made of meta l oxide and poly(organophosphazene) components is described. The main problem focused on during this research was to avoid phase separation in order to get homogeneous materials. This problem was pursued lookin g at the formation of genuine chemical bonds between the exploited pol yphosphazenes and the inorganic composite networks. Investigations on the thermal? mechanical, and electroconductive properties of the synth esized, phosphazene-containing composite materials showed that these m atrices presented improved mechanical and thermal Features with respec t to those of the original phosphazene macromolecule, while the ionic conductivities of the prepared molecular hybrids doped with lithium or silver triflate are of the same order of magnitude as those measured for the neat, original phosphazene substrate.
