摘要:
以聚苯胺水凝胶衍生碳为载体，通过在载体材料上原位生长二氧化锰，制备了聚苯胺水凝胶衍生碳/二氧化锰复合材料。通过X射线衍射、拉曼光谱、扫描电子显微镜及X射线光电子能谱仪对产物的化学结构、微观形貌和锰元素的价态进行了表征，并利用电化学技术对产物的超级电容性能进行了研究。研究结果表明，其具有较高的比电容（170 F·g-1）、良好的电化学响应及倍率特性、较低的阻抗，以及较好的循环稳定性（循环1 000次，比电容保持率为94.7%）。本文开发的聚苯胺水凝胶衍生碳/二氧化锰复合材料具有制备方法简单和纳米结构理想等优点，在高性能超级电容器电极材料领域具有良好应用前景。
Abstract:
The polyaniline hydrogel derived carbon/manganese dioxide composite（PHC/MnO2）was prepared by the in-situ synthesis of MnO2 on polyaniline hydrogel derived carbon. The chemical structure， micromorphology and valence state of Mn of products were characterized by X-ray diffraction，Raman spectrometry，field-emission scanning electron microscopy and X-ray photoelectron spectroscopy. Furthermore，the supercapacitive performance was studied by the electrochemical method. The results show that the prepared PHC/MnO2 possesses high specific capacitance （170 F·g-1），favorable electrochemical response and rate capability，low impedance，and good cycling stability（after 1 000 charge/discharge cycles，the specific capacitance retention is 94.7%）. Owing to the facile synthesis and ideal nanostructure，the PHC/MnO2 has bright prospect in the area of high performance electrode materials for supercapacitors.
