Surface modification of polymeric material

Abstract

Abstract PURPOSE:To modify the surface of a polymeric material so as to enable the control of the degree of grafting, without causing damage to substrate, by treating the surface of the polymeric material with corona discharge in open atmosphere, and carrying out the graft polymerization of a radically polymerizable monomer to the surface. CONSTITUTION:The surface of a polymeric material (e.g. polyethylene, nylon 6, etc.) is treated with corona discharge in open atmosphere to impose energy of 0.1m-Joule/cm<2>-100 Joule/cm<2> preferably for 0.01-10min, and is made to contact with one or more radically polymerizable monomers (e.g. styrene, acrylamide, etc.) in the form of vapor or solution. The monomers are grafted to the surface of the polymeric material e.g. by thermal polymerization, redox reaction, etc. to achieve the objective modification of the surface of the polymeric material.
