ABSTRACT:
A method is disclosed for making free standing multilayer films by depositing the films on a soluble substrate. The substrate solvent combination is chosen so that the solvent will not effect the multilayer materials. After deposition on the substrate, the multilayer films are cemented to a flat and smooth frame, in which a hole or window of the desired size and shape has been previously drilled. The adhesive, the films and the frame are insoluble in the chosen solvent for the substrate. After the adhesive is set, the substrate is dissolved leaving the multilayer film free standing within the frame. Also disclosed is a method for providing the films with a curvature.
