聚吡咯/氧化石墨烯复合材料的制备及电化学性能研究
|
摘要
分别采用物理球磨混合法、化学原位聚合法和化学原位聚合-还原法制备了聚吡咯/氧化石墨烯混合物、聚吡咯/氧化石墨烯(PPy/GO)和聚吡咯/还原氧化石墨烯(PPy/RGO)复合材料。通过三电极测试其电化学性能(循环伏安、恒流充放电和交流阻抗)。结果表明,通过化学原位聚合法制备的PPy/GO(304. 5 F/g)比电容远高于物理混合(16 F/g)和聚吡咯/还原氧化石墨烯(126. 4 F/g)。化学法原位聚合法制备PPy/GO最佳条件是冰浴条件下和加入表面活性剂对羟基苯磺酸钠。并通过X射线衍射(XRD)和扫描电子显微镜(SEM)对化学原位制备的PPy/GO组成、结构和形貌进行了表征。
Polypyrrole/graphene oxide mixtures,polypyrrole/graphene oxide( PPy/GO) composite and polypyrrole/reduced graphene oxide composite( PPy/RGO) are prepared by physical milling,chemical in-situ polymerization and chemical in-situ polymerization-reduction respectively. The electrochemical properties( cyclic voltammetry,galvanostatic charge and discharge,and AC impedance) are tested by three electrodes. The results show that the PPy/GO( 304. 5 F/g) prepared by chemical in-situ polymerization has much higher specific capacitance than physical mixing( 16 F/g) and polypyrrole/reduced graphene oxide( 126. 4 F/g). The chemical in-situ polymerization preferred condition is under ice bath condition and the addition of the surfactant sodium p-oxybenzenesulfonate. The structure and morphology of PPy/GO prepared by chemical in-situ polymerization are characterized by X-ray diffraction( XRD) and scanning electron microscopy( SEM).
