氧化石墨烯/聚吡咯/聚苯胺夹层复合材料的制备与储能研究

本文以吡咯（Py）、苯胺（ANi）为单体，氧化石墨烯（GO）为模板，采用原位依次聚合法制备氧化石墨烯/聚吡咯/聚苯胺（GO/PPy/PANi）夹层复合材料，并采用红外光谱法、循环伏安法、恒电流充放电法等手段对制备的夹层复合材料进行了结构和性能表征。红外光谱表明，GO仅作Py和ANi聚合的模板；循环伏安法和恒电流充放电法显示，在GO、Py、ANi的原料比为1:5:10时，材料的比电容最大，主要是基于氧化还原反应进行储能。本文所制备的夹层复合材料可作为超级电容器的电极材料，对解决能源危机与环境保护难题具有重要意义。

Preparation and energy storage research of graphene oxide/ polypyrrole/polyaniline sandwich composites

Abstract: Graphene oxide/polypyrrole/polyaniline (GO/PPy/PANi) sandwich composites were prepared by in-situ sequential polymerization, using pyrrole (Py) and aniline (ANi) as monomers, graphene oxide (GO) as a template. The structure and properties of the composites were investigated by infrared spectroscopy, cyclic voltammetry, constant current charge and discharge methods. Infrared spectroscopy showed that GO was only used as a template of polymerization of Py and ANi. Cyclic voltammetry and galvanostatic charge-discharge method indicated that the specific capacitance of the composite reached the maximum value when the feed ratio of GO/Py/ANi was 1/5/10. The composites were mainly based on redox reactions for energy storage. The composites can be used as electrode materials for supercapacitors, which are of great significance for solving the two major problems of energy crisis and environmental protection.
