Abstract

Interfacial polymerization is an innovative technique for the fabrication of polymeric films. However, the majority of studies on interfacial polymerization has focused on liquid/liquid interfaces, and little work has been done on vapor/liquid interfaces. In this paper, we present the fabrication of free-standing polypyrrole/polyaniline (PPy/PANI) composite films by interfacial polymerization at a vapor/liquid interface using FeCl as an oxidant. The obtained PPy/PANI composite films were characterized using Fourier transform infrared spectroscopy, X-ray diffractometry, and scanning electron microscopy. It was found that the PPy/PANI composite films consist of PANI particles evenly distributed on porous PPy film. The influence of FeCl concentration on the morphology of the resulting composite films was investigated. The PPy/PANI composite films show an excellent Cr(vi) adsorption capacity of 256.41 mg g, much higher than that of PPy-based absorbents prepared from chemical and electrochemical polymerization routes. This work thus suggests a new route for the fabrication of PPy/PANI films with highly enhanced Cr(vi) adsorption capacity for practical applications.

摘要

界面聚合是一种制备聚合物薄膜的创新技术。然而，大多数关于界面聚合的研究都集中在液/液界面，而在气/液界面方面的工作很少。在本文中，我们展示了以FeCl为氧化剂，通过在气/液界面进行界面聚合来制备独立的聚吡咯/聚苯胺（PPy/PANI）复合薄膜。使用傅里叶变换红外光谱、X射线衍射和扫描电子显微镜对所得的PPy/PANI复合薄膜进行了表征。结果发现，PPy/PANI复合薄膜由均匀分布在多孔PPy薄膜上的PANI颗粒组成。研究了FeCl浓度对所得复合薄膜形态的影响。PPy/PANI复合薄膜表现出256.41 mg g的优异Cr(Ⅵ)吸附容量，远高于通过化学和电化学聚合路线制备的基于PPy的吸附剂。因此，这项工作为制备具有高度增强的Cr(Ⅵ)吸附容量的PPy/PANI薄膜以用于实际应用提供了一条新途径。
