Brief Communications


Films of polymer/silica nanocomposites based don isotactic polypropylene and high density polyethylene are prepared via solvent-crazing in the tetrahydrofurane solution of molecular silica sol. This method allows us to disperse SiO2 particles with a diameter of 5–15 nm in a volume of polymer matrices homogeneously and at the nanometer level. The possibility of producing a fragmented riffled silica coating onto polymer surfaces is presented.
