Preparation of Triazine Thiol Polymeric Nano-film by Electrochemical Polymerization on Aluminum Surface

通过电化学的方法,利用一种自设计合成的6-N,N-烯丙基氨基-1,3,5-三嗪-2,4-硫醇(简称DAN)在金属铝表面制备高分子纳米薄膜.通过反射吸收红外光谱(RA-IR)对此三嗪硫醇的高分子纳米薄膜(PDA)的化学结构进行了确定.同时对于铝表面形成的PDA薄膜进行了接触角、膜厚和膜重测定.测定结果显示:只有在亚硝酸钠作为支持电解质的条件下,在铝的表面形成了三嗪硫醇高分子纳米薄膜;并且形成的三嗪硫醇高分子纳米薄膜的膜厚及重量与电解时间和电位成正比.通过原子力显微镜对不同电解电位条件下形成的薄膜表面形态和表面粗糙程度进行了评价,表明通过恒电位法使用较高的电解电位在铝表面获得了均匀致密的PDA薄膜,为在铝表面制备有机介电薄膜提供了研究基础.
