SYNTHESIS AND CHARACTERIZATION OF POLY(METHYL METHACRYLATE)-SILICA, -ALUMINA AND -SILICA-ALUMINA SOL-GEL NANOCOMPOSITES

The development of nanostructructured polymethilmethacrylate (PMMA) surfaces was studied by the incorporation of silica, alumina and silica-alumina, the former obtained by Sol-gel procedure. The materials were obtained in a polymer solution (acetone, isopropanol) and contains variable amounts of the...
