Surface modification of polymer insulator by plasma surface treatment

In this study, composite materials were put to dry interfacial treatment by use of plasma technology. It has been presented that the optimum parameters for the best wettability of the samples at the time of generation of plasma were oxygen atmosphere, 0.1 torr of system pressure, 100 W of discharge power, and 3 minutes of discharge time. The contact angles of the samples treated under the optimum conditions and the samples that had not been treated at all were 78/spl deg/ and 72/spl deg/, respectively.
