摘要

利用 PECVD 技术合成了异戊二烯与丙烯酸的共聚物薄膜。通过这种方法，聚异戊二烯（PI）的可拉伸功能与聚（丙烯酸）（PAA）的亲水功能相结合，获得了润湿性可调的可拉伸薄膜。根据单体流速的不同，沉积速率在 9 至 5.5 nm/min 之间变化。水接触角 (WCA) 值分析表明，薄膜结构中 AA 单元越多，润湿性越好。通过拉伸释放测试评估了薄膜在实验室手套上的拉伸性，通过弯曲释放测试评估了薄膜在 PET 片材上的拉伸性。连续测试后，WCA 值没有明显变化，也没有观察到裂缝和失效，这表明共聚物薄膜具有拉伸性。

Synthesis and characterization of stretchable isoprene-acrylic acid copolymer thin films

Copolymer thin films of isoprene with acrylic acid were synthesized using PECVD. In that way, the stretchable functionality of polyisoprene (PI) was combined with the hydrophilic functionality of poly(acrylic acid) (PAA) to obtain stretchable thin films with adjustable wettabilities. Deposition rates were found to change between 9 and 5.5 nm/min depending on the monomer flowrates. The analysis of water contact angle (WCA) values indicated that films having more AA units in their structures were more wettable. The stretchability of the films was assessed on laboratory gloves through stretch-release test and on PET sheet through bend-release test. No significant changes in the WCA values with no observable cracks and failures after successive tests were indication of stretchability of the copolymer films.

期刊介绍： The aim of this international journal is to analyse and publicise the progress and current state of knowledge in the field of organic coatings and related materials. The Editors and the Editorial Board members will solicit both review and research papers from academic and industrial scientists who are actively engaged in research and development or, in the case of review papers, have extensive experience in the subject to be reviewed. Unsolicited manuscripts will be accepted if they meet the journal''s requirements. The journal publishes papers dealing with such subjects as: • Chemical, physical and technological properties of organic coatings and related materials • Problems and methods of preparation, manufacture and application of these materials • Performance, testing and analysis.
