A Study of an Electrodeless Glow Discharge as a Means of Modifying the Surface of Polymers.

Abstract

A method of modifying the surface of materials for use in prosthetic devices in contact with blood has been developed by the deposition of glow discharge polymer. The effect of choice of monomer and of operational parameters on the chemical nature of the glow discharge polymer has been extensively elucidated. Good reproducibility has been demonstrated and tests by other contractors have indicated promising blood compatibility. The method therefore yields a very thin (50-1000 A), highly adhesive and cohesive coating that does not affect the bulk properties of the substrate. Surfaces with a wide range of chemical properties are accessible by this technique. In the last year of the project a barrier to leaching of plasticizer from poly(vinyl chloride) has been formed by glow discharge treatment and a change of chemical properties for tetramethyldisiloxane glow discharge polymer has been found with aging.
