| 中文摘要: |
| 超级电容器具有功率密度高、充放电速度快、循环寿命长和维护成本低,在电动车动力电池领域具有潜在的应用前景。超级电容器性能主要受电极材料决定。聚苯胺具有易合成,高理论比容量和优异导电性能,在超级电容器电极材料中有很高应用价值。但是在长期使用过程中,体积容易发生膨胀或收缩,循环寿命差。为了解决这个问题,将聚苯胺与石墨烯复合可以扬长避短,充分利用两者之间的协同效应,赋予复合材料优异电化学电容性能。因此本文综述了超级电容器用石墨烯-聚苯胺复合材料的制备方法,包括原位聚合法、油水界面合成法、电化学合成法、层层自组装法等。提出三维网状石墨烯和对石墨烯-聚苯胺复合材料进行改性来提高复合材料的电化学电容性能的思路。 |
| 英文摘要: |
| Supercapacitors hold a great potential application in electric vehicles due to high power density, short charge-discharge time, long cycle life and low maintenance cost. The performance of supercapacitor is determined by electrode materials. Polyaniline has been largely reported for the use of supercapacitors because of high theoretical specific capacity, easy synthesis, low cost and good electrical conductivity. However, polyaniline occurs volume swelling and shrinkage during the long charge-discharge process, which leads to decreasing electrochemical capacitive performance. In order to deal with this problem, polyaniline compounded with graphene is a good way to improve the electrochemical capacitive properties, which is attributed to synergistic effect. Therefore, the synthetic methods for graphene-polyaniline composite were reviewed in this work, including in-situ polymerization, oil-water interfacial polymerization, electrochemical polymerization, layer-by-layer assembly method and et al. Three dimensional network graphene and modification for graphene-polyaniline composite were new ideas in order to improve the electrochemical capacitive properties of as-prepared composite. |
