Nano–ZnO\poly(methyl methacrylate)(PMMA) composite latex microspheres were synthesized by insite emulsion polymerization. The interfacial compatibility between nano–ZnO particles and PMMAwere improved by treating the surface of nano–ZnO particles with hydrophobically stearic acid.Stearic acid as a modifying factor in the core–shell SiO2\ZnO nanoparticle affect on the properties and applications. TEM indicated that nano–ZnO particles present in nanosphere and have beenencapsulated in the PMMA phase. FT–IR confirmed that, stearic acid reacted with the nano–ZnOparticle and copolymerized with MMA. It was clearly found from SEM that ZnO nanoparticles can be homogeneously dispersed in the PMMA matrix<\div>
