Modification of the track membrane surface by ultrathin films of polysiloxane block copolymers

Abstract

Modification of the surface of PETP (Dacron) track membranes by ultrathin films of polysiloxane block copolymers provides new composite membranes with a hydrophobic surface and retained pore space. It is demonstrated that a uniform distribution of a nanodimensional modifier (fullerene) in a polymer matrix can be achieved, which ensures a high strength of the composite layer.
