摘要
采用γ射线辐照的方法对pp膜进行了表面处理,并且对pp膜的表面张力、接触角以及油墨的附着力进行了测试。结果显示,随着辐照剂量的增加(0-25kGy)pp膜的表面张力逐渐增加;膜与油的接触角先减小后增加,在辐照剂量为5kGy时达到最小值(15.5°),而与水的接触角逐渐减小;油墨的附着力明显增加。
γ radiation was used in processing pp films. Surface tension of films, contact angle, and absorbability of ink were tested and discussed. The results showed that with the increasing of γ radiation dose, surface tension and absorbability of ink increased, but the contact angle to water decreased, and the contact angle to oil reached the minimum （ 15.5° ）.
