In Situ Preparation of Polymer Nanocomposites Based on Sols of Surface-Modified Detonation Nanodiamonds by Classical and Controlled Radical Polymerization

Abstract

The possibility of surface modification of detonation nanodiamonds to give them dispersability in methyl methacrylate is considered. In situ polymer composites are obtained by classical radical polymerization and reversible chain-transfer polymerization based on stable sols of detonation nanodiamonds in a monomer. Evidence that nanodiamonds are dispersed in a polymer matrix up to a size of units of nanometers is given. The effect of detonation nanodiamonds on the molecular weight characteristics and glass transition temperature of poly(methyl metacrylate) obtained in their presence is studied.
