Effect of Plasma Surface Treatment on Electrical and Mechanical Properties of Poly(ethylene terephthalate ) Film
플라즈마 표면처리가 Poly(ethylene terephthalate) 필름의 전기적 및 기계적 성질에 미치는 영향
Abstract
In this study the electrical and mechanical characteristics of PET films ore analyzed after plasma surface treatment. After plasma treatment, the surface potential decay, surface potential and dielectric property were evaluated to analyze the electrical insulating property, and the tensile strength was measured as the mechanical characteristic. When plasma treatment was conducted for less than 10 minutes, it was found that the electrical insulating property was improved through evaporation of low molecular weight materials md cleaning of surface. However, for more than 10 minutes, the insulating property of plasma treated PET films was decreased due to excessive discharge energy. The tensile strength was hardly changed by Plasma treatment.
