Abstract

The supercapacitive properties of the polythiophene (PTh) and its composites with iron dust synthesized by chemical oxidative polymerization are investigated. The UV–Vis, FTIR, TGA, XRD, SEM, and EDX were used to characterize the composites. Iron (Fe) dust is inserted into PTh matrix as confirmed by FTIR, UV–Vis, EDX, and XRD analysis. The TGA shows that composites have higher thermal stability than pure PTh. The SEM reveals highly porous and packed morphology of the composites as compared to pure PTh. Cyclic voltammetry (CV), galvanostatic charge–discharge (GCD), and electrochemical impedance spectroscopy (EIS) show that a 1:1 ratio by mass of PTh and Fe composite displayed greater specific capacitance than pure PTh. The high specific capacitance of the composite material (428.46 F/g at 1 A/g) suggested that the material is suitable for supercapacitor electrode. Cyclic stability is also tested for 1000 cycles at a current density of 1 A/g with excellent retention of 88.89%.

利用化学氧化聚合法合成的聚噻吩/铁粉复合材料的电化学特性

研究了通过化学氧化聚合法合成的聚噻吩（PTH）及其与铁粉的复合材料的超级电容特性。复合材料的表征采用了紫外可见光、傅立叶变换红外光谱、热重分析、X射线衍射、扫描电镜和电离辐射显微镜。傅立叶变换红外光谱（FTIR）、紫外可见光光谱（UV-Vis）、电离辐射 X 射线衍射（EDX）和 X 射线衍射（XRD）分析证实，铁（Fe）粉尘被加入到 PTh 基体中。热重分析表明，与纯 PTh 相比，复合材料具有更高的热稳定性。扫描电子显微镜（SEM）显示，与纯 PTh 相比，复合材料具有高多孔性和填充形态。循环伏安法（CV）、电静态充放电法（GCD）和电化学阻抗光谱法（EIS）显示，按质量比为 1:1 的 PTh 和铁复合材料比纯 PTh 显示出更大的比电容。复合材料的高比电容（1 A/g 时为 428.46 F/g）表明该材料适用于超级电容器电极。此外，在电流密度为 1 A/g 的条件下，还进行了 1000 次循环稳定性测试，结果表明其保持率达到 88.89%。

期刊介绍： The Journal of Solid State Electrochemistry is devoted to all aspects of solid-state chemistry and solid-state physics in electrochemistry. The Journal of Solid State Electrochemistry publishes papers on all aspects of electrochemistry of solid compounds, including experimental and theoretical, basic and applied work. It equally publishes papers on the thermodynamics and kinetics of electrochemical reactions if at least one actively participating phase is solid. Also of interest are articles on the transport of ions and electrons in solids whenever these processes are relevant to electrochemical reactions and on the use of solid-state electrochemical reactions in the analysis of solids and their surfaces. The journal covers solid-state electrochemistry and focusses on the following fields: mechanisms of solid-state electrochemical reactions, semiconductor electrochemistry, electrochemical batteries, accumulators and fuel cells, electrochemical mineral leaching, galvanic metal plating, electrochemical potential memory devices, solid-state electrochemical sensors, ion and electron transport in solid materials and polymers, electrocatalysis, photoelectrochemistry, corrosion of solid materials, solid-state electroanalysis, electrochemical machining of materials, electrochromism and electrochromic devices, new electrochemical solid-state synthesis. The Journal of Solid State Electrochemistry makes the professional in research and industry aware of this swift progress and its importance for future developments and success in the above-mentioned fields.
