摘要
以苯胺(ANi)为单体,过硫酸铵(APS)为氧化剂,氧化石墨烯(GO)为模板,调节ANi与GO原料质量比从0.5到100,采用原位聚合法制备了一系列不同组分含量的聚苯胺/氧化石墨烯(PANi/GO)复合材料。采用傅里叶变换红外光谱、X射线衍射谱、扫描电镜和循环伏安法对制备复合材料的结构、微观形貌和循环伏安性能进行了研究,着重考察了原料配比对PANi/GO复合材料结构、微观形貌及能量存储的影响。研究表明:ANi单体成功原位聚合在GO表面上;ANi/GO质量比对PANi/GO复合材料的比电容影响明显;随着ANi/GO质量比的增加,所制备复合材料的比电容先增加后减小。当ANi/GO质量比为10、扫描速率为10 m V·s^(–1)时,复合材料的比电容达到最大值162.2 F·g^(–1)。
A series of polyaniline/graphene oxide(PANi/GO)composites were prepared via in situ polymerization using aniline(ANi)as monomer,GO as templates,ammonium persulfate(APS)as an oxidant,and the mass ratio of ANi to GO was from0.5to100.The structure,morphology and cyclic voltammetry performance of the composites were studied by FT-IR,XRD,SEM and cyclic voltammetry(CV).The effects of ANi/GO feed ratios on the structure,morphology and energy storage of PANi/GO composites were investigated in detail.The results indicate that ANi is polymerized on the surface of the GO,and the specific capacitance of the composites is significantly influenced by the feed ratios of ANi to GO.With the increasing of ANi/GO mass ratio,the specific capacitance of the resulting composites increases at first and then decreases,and reaches the maximum value of162.2F·g-1at the mass ratio of10and scanning rate of10mV·s-1.
