摘要
聚吡咯(PPy)是一种十分重要的导电聚合物,拥有优秀的导电性能和导热性能,因而被广泛应用于生物医学、储能科学和传感器的研究领域。由于PPy在循环工作过程中体积会发生一定的改变,GO片材料的复合使用对提高PPy的循环稳定性具有重要意义。通过TB改性GO,采用原位聚合方法通过含吡咯(Py)的改性GO悬浮液形成复合材料,将该材料进行电化学性能测试,发现得到的PPy-TB-GO复合材料具有高比电容和良好的循环稳定性,是极具潜力的超级电容器材料。
Polypyrrole(PPy)is a very important conductive polymer with excellent conductivity and thermal conductivity,which is widely used in biomedicine,energy storage science and sensor research.Because the volume of PPy will change in the process of cyclic operation,the composite use of go sheet material is of great significance to improve the cyclic stability of PPy.In this paper,GO was modified by TB,and the composite was formed by in-situ polymerization of GO suspension containing pyrrole(py).The electrochemical performance of the material was tested.It was found that PPy TB GO composite had high specific capacitance and good cycle stability,which was a potential super capacitor material.
