Title Preparation and characterization of hybrid nanocomposites coatings by photopolymerization and sol-gel process
Date 28.11.2005
Abstract Organic-inorganic nanocomposite hybrid coatings were prepared through a dual-cure process involving cationic photopolymerization of epoxy groups and subsequent condensation of alkoxysilane The kinetics of the photopolymerization and condensation reactions were investigated; Suitable conditions for obtaining a complete conversion of both reactive groups were found. The obtained films, are transparent to visible light. The T(g) values of the hybrids increase by increasing the TEOS content in the photocurable formulation. Also, a significant increase in surface hardness could be obtained for the hybrid system.. AFM analysis gave evidence of a strong interaction between the organic and inorganic phase with the formation of silica domains ill the nanoscale range. (c) 2005 Elsevier Ltd. All rights reserved.
