Ceramic nanoparticles are synthesized by a microwave plasma process and coated with a polymer layer generated in situ by photopolymerization. Acrylic and methacrylic monomers are the most suitable precursors for polymer coatings. In the case of coatings derived from MMA, only a small quantity of the polymeric material is soluble in organic solvents. GPC analysis of the dissolved part reveals the predominance of oligomers. According to FT‐IR spectra, a substantial number of MMA‐ester groups is transformed into carboxylates, providing strong adhesion of the polymer to the ceramic core insoluble in THF. Composites with PTFE‐analog coating exhibiting enhanced thermal and chemical stability are obtained from the condensation of perfluorinated alkanes on metal oxide nanoparticles.
