水溶性聚合物和两亲聚合物——10.两亲聚合物PAMC_(16)S的自组装有序膜

Water-Soluble and Amphiphilic Polymers: 10. Ordered films by self-assembly of an amphiphilic polymer PAMC_(16)S

摘要: 用自组装技术在金(纯金和经阳极氧化的金)表面上获得了新型两亲聚合物PAMC_(16)S的有序膜。用接触角测试,XPS谱和电化学分析等方法对自组装膜进行了表征。根据膜表面的润湿性,金表面的自组装膜是疏水的,亲水的磺酸基团连于金表面,而疏水的碳氢链从表面伸展出。XPS实验结果支持金表面上单层膜的疏水结构。聚合物单层膜复盖的金电极起到含有针孔缺陷的阻膈型电极的作用。单层膜在法拉第反应中显示很强的吸附稳定性,说明聚合物LB膜在潜在应用中有其特有的特点。

Abstract: Ordered films of a novel amphiphilic polymer PAMC_(16)S have been obtained on gold surfaces (clean gold and anodized gold) by self-assembly technique. The self-assembled films have heen characterized by contact angle measurements, XPS and electrochemical
