Novel PET/In-situ Fabricated Sheet-like Titanium Compound Nanocomposite with Excellent Processing and High effective UV Shielding Abilities

摘要

OrganicCinorganic hybrid materials have promisingly potential of application since they could combine the good properties of organic and inorganic materials. The in-situ sol-gel process is one of the important methods for preparation of organicCinorganic hybrid materials. In recent twenty years, researchers paid much attention to effectively combine the sol-gel process and polymer synthesis, process and application in order to develop high performance polymer based nanocomposites. The method of in-situ blending precursor and polymer, the method of in-situ blending sol and polymer and the method of in-situ polymerization of sol and polymer monomers have been intensively studied. However, there have little reports about the method of in-situ polymerization with precursors except from our research group. Polyesters, such as PET, PBT and aliphatic polyester, are the important raw materials of plastics, fibers, coatings etc. Therefore, it has important academic and industrial significance to study the structure change of precursor during the PET synthesis and its mechanism.
