| 摘要 |
A method of forming a coating on a substrate surface which coating comprises SiOx groups by plasma treatment of the surface, wherein the substrate comprises a blend of an organic polymeric material and an organosilicon-containing additive which is substantially non-miscible with the organic polymeric material. The organic polymeric material preferably comprises a poly-olefin, and the organosilicon-containing additive preferably comprises polydimethylsiloxane, alpha,omega-dihydroxypolydimethylsiloxane, alpha,omega-divinylpolydimethylsiloxane, or a copolymer of polydimethylsiloxane and polyethylene. The plasma treatment may comprise oxygen-containing gas plasma treatment, and the substrate is preferably heated and the plasma pulsed during plasma treatment. The method can enhance the surface barrier, antioxidant and/or the adhesive properties of the substrate.
