摘要
利用非离子表面活性剂 Triton X-100 通过化学氧化工艺制造了一种多孔结构的共聚物聚（苯胺-邻苯二胺）。使用了不同比例的单体（1:9、5:5 和 9:1），并通过傅立叶变换红外光谱（FTIR）和扫描电镜-电子显微镜（SEM-EDX）技术分析了结构和表面形态。此外，还进行了紫外线、X 射线衍射和 BET 表面积测量。循环伏安法和电化学阻抗等电化学技术用于评估电化学电容性能。由等摩尔单体混合物组成的共聚物显示出较高的表面积，有助于扩大电解质离子的扩散。因此，在电流密度为 5 mA cm-2 时，通过电静态充放电研究确定了所开发共聚物的比电容为 989 F g-1，100 次循环后电容保持率为 84.94%。
Synthesis of copolymer of aniline-o-phenylenediamine using nonionic surfactant Triton X-100: analysis of electrical conductivities and supercapacitor properties
A porous structure of copolymer poly (aniline-co–o-phenylenediamine) has been fabricated by chemical oxidation process with nonionic surfactant Triton X-100. Different ratios of monomers (1:9, 5:5 and 9:1) have been utilized; structure and surface morphology has been analyzed by FTIR and SEM–EDX techniques. The UV, XRD and BET surface area measurement were also done. The electrochemical techniques such as cyclic voltammetry and electrochemical impedance were used to evaluate electrochemical capacitance performances. The copolymer comprising equimolar mixture of monomers displayed high surface area that helps to amplify the diffusion of electrolyte ions. Hence, the specific capacitance of developed copolymer has been determined as 989 F g−1 at 5 mA cm−2 current density from galvanostatic charge–discharge studies with retainability of 84.94% capacitance after 100 cycles.
