Composition-Structure-Properties Relationship and Durability of Modified Organosilicate Polymeric Composite

Abstract

The present work was aimed at the development of new organosilicate polymeric composite, based on polydimethylphenylsiloxane/polyurethane (PDMPS/PU) miscible blend, filled with silicates and metal oxides. Considerable improvement of mechanical and corrosion-protective properties due to introduction of polyurethane has been observed. Coatings with sufficient thermostability (up to 300°C) have been obtained in the case of 20% polyurethane content, related to amount of binders. The effects coating heat treatment temperature and curing conditions on adhesion of metal/composite interface have been studied. Surface energy characteristics of this coating have been obtained and were correlated with its microstructure, determined from Scanning Electron X-ray Microprobe Analyses. Recently developed composite appeared to show increased durability in atmosphere operation conditions.

The current state of the art in materials science of organosilicate composites

“…However, this approach allows one to achieve substantial progress in preparation of high-quality durable materials, does not require considerable costs in order to develop new synthesis procedures and new technological processes, and, as before, is widely used for designing organosilicate composites [40][41][42][43].…”
