Organic-inorganic nanocomposites have attracted much attention because they may combine the advantages of both traditional organic polymers and inorganic materials. The sol-gel processing provides high thermal stability, good mechanical strength, and show high transparency for development of optical materials. Recently, various POSS with the caged-structure were synthesized by the hydrolysis, and condensation reaction of silane compounds. The sol-gel reaction which is one of the most effective methods to prepare the hybrid materials has been widely used so far because of the condition of ambient temperature and high uniformity of organic parts in the silica matrix. In this study, polymer hybrids were prepared by octasilsesquioxanes having methoxyl groups and organic polymer polyvinylpyrrolidone using hydrogen bonding interaction. The composition, structure and thermal properties of the hybrid materials were characterized by various analytical tools. |
