介质阻挡放电等离子体处理对麦秸秆表面润湿性能的影响
Influence of dielectric barrier discharge plasma treatment on wettability of wheat straw
摘要
Abstract
The surface of wheat straw was treated by dielectric barrier discharge ( DBD) plasma. The influence of dis-charge voltage, electrode space and treatment time on the wettability of wheat straw was investigated. The results showed that lower contact angle and higher surface free energy of the samples were achieved after being treated by DBD plasma, which means the wettability of wheat straw was improved, especially for exterior surface of wheat straw. In addition,along with the increase of discharge voltage, the decrease of the electrode space and the extension of treatment time, the con-tact angle of wheat straw showed the tendency of decreasing at first and then increasing, and the surface free energy showed the opposite tendency. The optimal treatment condition was:discharge voltage 30 V, treatment time 60 s, elec-trode space 6 mm.关键词
