摘要
为了实现聚丙烯(PP)薄膜的功能化,需要在聚丙烯薄膜的惰性表面引入可反应的活性官能团。文章采用介质阻挡放电(DBD)等离子体技术对聚丙烯薄膜进行处理,并优化处理工艺参数,通过水接触角测试表征处理效果;然后接枝丙烯酸(AAc),通过FTIR和SEM对接枝产物进行分析。结果表明:当处理工艺参数为:电压100V、时间60s、气体流速1.5L/min时处理效果较好,并能较好地实现聚丙烯薄膜的丙烯酸接枝。
In order to functionalize polypropylene （PP）, it is necessary to introduce the activated functional group. In this paper, PP film was treated by DBD plasma technology, and the technological parameter was optimized. The modification results were characterized by water contact angle. Then, acrylic acid （AAc） was grafted. The grafted product was analyzed by FTIR and SEM. The results show that the treat effects are good under the following conditions： voltage 100 V, time 60 s, gas flow velocity 1.5 L/min. in addition, under such conditions, acrylic acid can well be grafted on polypropylene film.
