摘要

Poly(ethylene glycol) methyl ether methacrylate?(PEGMA) was grafted on fluorosilicone acrylate rigid gas permissible contact lens surface by means of argon plasma induced polymerization to improve surface hydrophilicity and reduce protein adsorption.The surface properties were characterized by contact angle measurement,x-ray photoelectron spectroscopy(XPS) and atomic force microscopy respectively.The surface protein adsorption was evaluated by lysozyme solution immersion and XPS analysis.The results indicated that a thin layer of PEGMA was successfully grafted.The surface hydrophilicity was bettered and surface free energy increased.The lysozyme adsorption on the lens surface was reduced greatly.
