Abstract
The surface modification by atmospheric pressure barrier discharge is effective in the improvement of adhesion performance of plastics. The remote plasma processing has several advantages against the direct plasma processing. They are free from the problem of surface damage and the charge accumulation and have larger freedom of setup of the system. However, it is necessary to improve the processing performances such as range of remote processing distance, reduction of contact angle and so on.
In this paper, we have investigated processing performances of the remote surface reforming. We used polyethylene film as the reforming object. It was found that the followings are very effective as processing condition; (1) use of nitrogen gas, (2) high speed gas flow and, (3) longer processing time.
