摘要
聚苯胺(PANI)作为一种导电高分子材料具有较高的比电容、良好的环境相容性以及易制得等优点在能源储存、传感器以及电磁屏蔽等领域有着广泛的应用前景。但是由于聚苯胺自身结构的原因传统化学法所制备的聚苯胺极易发生团聚从而造成聚苯胺分散性差的形貌,而这对聚苯胺用作超级电容器电极材料造成了不利的影响。因此对聚苯胺形貌的有效控制已经成为当前研究的重点。有鉴于此,本工作对ZIF-9进行热处理以及酸刻蚀,成功制备出了碳材料。并以其为PANI聚合反应基底以期望对PANI复合材料的形貌进行一定的控制。该方法制备的聚苯胺复合材料显示出一定的电化学性能。在当反应物浓度为0.05 M时达到最大放电比电容约为195 F·g^(-1)。
It is known to us all that polyaniline(PANI)is one kind of conducting polymer,which can be easily prepared.Due to it is high specific capacitance and good environmental compatibility,PANI has been applied in a wide range of fields,including energy storage,sensors,electromagnetic shielding and so on.However,the polyaniline prepared by traditional chemical method is easy to agglomerate,which results in the poor dispersion of polyaniline.This phenomenon has a negative effect when polyaniline is used as the electrode material of supercapacitor.Therefor it is more and more important to control the morphology of PANI.According to this,our work introduced the wet ball-milling into the chemical preparation of polyaniline,which can easily inhibit the agglomeration and dispersion process of PANI due to the contribution of the strong mechanical force during the polymerization process.The PANI composites prepared by this method show certain electrochemical properties.The capacity of PANI composites can reach about 195 F·g^(-1),when the reactant concentration is 0.05 M.
