摘　　要：常压下用等离子体来处理材料,使其表面能增强,对材料进行消毒、清洁等比真空等离子体技术有优势,为研究应用该技术,在实验室中开发了一套在常压下用空气做原料连续处理材料的等离体子体设备。试制了几种不同的电极结构,以使其产生均匀的等离子体,最后确定采用旋转轮做接地电极,铜平板做高压高频电极,耐热玻璃做绝缘介质的等离子体产生结构。试验了几种不同的绝缘材料做阻挡介质后综合考虑采用耐热玻璃做阻挡介质,并比较了产生的等离子体以及对材料的处理结果,证实经过等离子体处理之后材料的表面能大大增强。Industrial atmospheric pressure plasma treatment has unique advantages over vacuum plasma technology for material surface energy enhancement, surface cleaning and decontamination, sterilization, surface etching and related tasks. A roll-to-roll device was set up in laboratory to process films and fabrics at constant atmosphere pressure. In order to produce uniform plasma, different electrode structures were designed and tested, at last the drum as ground electrode and copper plate as high voltage electrode was selected, several different dielectric materials were selected, and Pyrex was selected as the barrier. Measurements of the surface energy by the sessile water drop and related tests show that the surface energy is raised after plasma treatment.
