摘要
利用rGO、PPY和CoNd-LDH三种材料,采取原位聚合法,制备PPY、PPY/rGO、PPY/CoNd-LDH、PPY/rGO/CoNd-LDH等新型复合材料。借助扫描电镜、X射线衍射分析、红外光谱和电化学分析等表征测试手段,分析材料的形貌、微观结构和电学性能。结果表明三元复合物电流密度1 A/g时的比电容达到594 F/g,相比纯PPY比电容提升184.2%,相比PPY/RGO,PPY/CoNd-LDH二元复合碳材料比电容提升74.7%和28%,并具有良好的循环稳定性。结果表明,PPY/RGO/CoNd-LDH复合材料是很有前途的超级电容器电极材料。
Three materials, rGO, PPY and CoNd-LDH, were used to prepare new composites such as PPY, PPY/rGO, PPY/CoNd-LDH and PPY/rGO/CoNd-LDH by in situ polymerization method. The morphology, microstructure and electrical properties of the materials were analyzed by means of characterization tests such as scanning electron microscopy, X-ray diffraction analysis, infrared spectroscopy and electrochemical analysis. The results show that the specific capacitance of the ternary complexes reaches 594 F/g at a current density of 1 A/g, which is 184.2% higher than that of pure PPY, 74.7% higher than that of PPY/RGO, and 28% higher than that of PPY/CoNd-LDH binary composite carbon materials, and has good cycling stability. The results indicate that PPY/ RGO/CoNd-LDH composites are promising electrode materials for supercapacitors.
