摘要 利用氧气低温等离子体,在真空度为20 Pa,处理功率为30 W的条件下,对高密度聚乙烯(HDPE)薄膜进行了表面改性。研究结果表明:在20~200 s的处理时间内,单位面积的失重率随处理时间的增加线性增大,表面粗糙度也随着增加;处理后薄膜表面的接触角显著减小;接触角越小,剥离强度就越大;处理后能在薄膜表面形成羟基、羰基和羧基等各种极性基团。 Modify the thin film of HDPE(High Density Polyethylene) by using low temperature plasma of oxygen at 20 Pa of vacuum and 30 W of processing power.The results show that: between 20~200 s,the weight loss rate per area unit and surface roughness increase with the processing time;The contact angles of the film surface reduce dramatically after processing;the smaller the contact angle is,the greater the peel strength will be;the thin film surface will form some polar species such as hydroxyl,carbonyl and carboxyl after processing.
