【摘要】 本文采用平板式电容耦合射频(RF,13.56MHz)等离子体源,以丙烯胺(allylamine)为聚合单体,氩气为辅助气体,沉积含胺基的功能薄膜。实验研究了等离子体放电功率对聚合物表面结构、稳定性和功能团含量等的影响。利用傅立叶变换红外光谱(FTIR)、X射线光电子能谱(XPS)和视频光学接触角测量仪(DSA100),对同一条件下聚合胺基薄膜的结构、成分进行了细致的分析。结论是:等离子体PECVD方法能有效的聚合富含胺基的薄膜,且胺基的含量随功率增加而增大,一定范围内,功率越大,薄膜的化学结构与单体更相近,功能团密度越多,而且制备的薄膜的稳定性较好。更多还原

【Abstract】 Using allylamine monomer,amine-containing functional films are prepared by plasma-enhanced vapor chemical deposition (PECVD).We explore the influences of the applied power on the film properties.The structure of coatings,deposited under the same conditions,is analyzed by Fourier transform infrared (FTIR) spectroscopy,X-ray photoelectron spectroscopy (XPS) as well as water contact angle (WCA).The conclusions show that plasma -enhanced vapor chemical deposition (PECVD) can polymerize rich amine-containing functional films with good stability,and the discharge power has great influences on the film properties.更多还原
