Abstract:
A method of molding a polymeric material to create a desired texture therein using an alumina mold having a plurality of cylindrical pores disposed therein, the method comprising the steps of: a) providing a porous alumina master having a plurality of cylindrical pores dispersed therein, said plurality of cylindrical pores corresponding to projections to be imparted to a surface of a film; disposing a polymeric material between a film and the porous alumina master; and c) applying mechanical pressure to roll the porous alumina master into the polymeric material, wherein the texture imparted to the polymeric molding material comprises projections corresponding to the cylindrical pores of the porous alumina master. A release agent is applied to the porous alumina master prior to disposing the polymeric molding material between the porous alumina master and the film.
