<p>Two (or more) continuous porous polymeric matrices are employed, one of which is microporous, in which the polymers matrices interpenetrate the porous areas of the other. Thus, the invention is a composite membrane made from two polymers. Thus, a composite of strong interpenetrating matrices is formed which exhibits properties of both polymers. For example, one polymer can impart strength, the other polymer improved radiation resistance, or one polymer can impart strength and the other improved reflectance of light.</p> |
