| 摘 要： | 利用等离子体处理聚丙烯(PP)薄膜后在气相环境中引发丙烯酸在其表面接枝聚合.实验结果表明,接枝处理15 min即可使PP薄膜的接触角从97°降至32°,说明亲水性大幅提高.红外光谱和扫描电镜分析表明,丙烯酸已接枝在PP薄膜表面,生成了众多l～2 μm的凸起物.经l0 min沸水处理后,接枝PP薄膜的水接触角无明显增加,...

| Abstract: | Polypropylene (PP) film was treated by cold plasma and followed by a vapor phase graft polymerization of acrylic acid (AAc). It was found that 15 minutes grafting was sufficient enough to decrease the water contact angle (WCA) of PP film from 97&;#61616; to 32&;#61616;, which indicates a great improvement in its hydrophilicity. FTIR-ATR study confirmed the grafting of AAc on PP film. SEM observation clearly showed many bump-like substances in the size of around 1-2&;#61549;m. This modified hydrophilicity kept very well even after washing the grafted sample in boiling water for 10 minutes, which indicates that the ageing effect of merely plasma-treated PP film was overcome. By investigating the effect of reaction time and temperature on the degree of grafting, an optimum condition was found as grafting for 15min at 55&;#61616;C. Under the optimum condition, the degree of grafting and WCA of grafted sample reached 0.45% and 32&;#61616;, respectively. It was thought that this fast and effective method of graft polymerization in vapor phase could provide a strong experimental support to develop corresponding industrial applications in the field of surface modification. |
