Preparation of Scratch and Aging Resistant Nanocomposite Coating on PVC Substrate

摘要

A nanocomposite coating was prepared on the surface of PVC (Poly Vinyl Chloride) substrate using spinning technique with attempt of incorporating α-FeOOH nanoneedles into the organic-inorganic hybrid matrices. The hybrid matrices were derived from tetraethoxysilane (TEOS) and 3-glycidoxypropyltrimethoxysilane (GLYMO) with a process of hydrolysis and condensation. It was found that the colorless and transparent nanocomposite coating endowed PVC substrate outstanding scratch and aging resistance.
