【Abstract】 Couples of PTFE samples have been treated in oxygen plasma vessel. The treated couples include compression-shearing ones and tensile. After bonded with epoxy adhesive and cured at room temperature in a week, their compression-shearing strength and tensile strength have been tested. The sample’s contact angles have been examined before and after oxygen plasma modification, meanwhile the morphology has also been investigated by means of AFM.更多还原
