不同掺杂聚苯胺膜对乙醇气体的吸附性能

Adsorption Capabilities Of Ethanol Gas on the Different Doped Polyaniline Films

摘要: 采用恒电流法制备不同掺杂的聚苯胺膜，通过循环伏安法对不同掺杂聚苯胺膜的吸附性能进行了研究，并采用扫描电子显微镜分析了不同掺杂聚苯胺膜的表面形貌特征。结果表明：3种不同掺杂的聚苯胺膜（PAn)对乙醇分子都有吸附性能，其中质子酸掺杂的PAn和纳米ZnO掺杂的PAn对乙醇分子的吸附性能较好，而KCl掺杂的PAn吸附性能相对较差，其吸附性能与掺杂前后聚苯胺膜的结构有关。

Abstract: Different doped polyaniline films were prepared by galvanostatic method at low current density. The adsorption properties of different doped polyaniline films were studied using cyclic voltammetry, and the surface morphology was analyzed using scan electron microscopy. The results indicate that three different doped polyaniline films(PAn) have different adsorption properties to ethanol molecules. Compared with KCl/PAn, PAn and ZnO/PAn have better adsorption capabilities. The adsorption properties are relative with the structure of the polyaniline films.
