Abstract

Supercapacitors have drawn a lot of interest as energy storage devices because of their high-power density, quick charge/discharge rates, and long cycle life. However, the creation of cutting-edge electrode materials is essential in order to further improve their performance. Nanostructures made of graphene-based conducting polymers have shown promise because they combine the special qualities of both graphene and conducting polymers. In the present research, we synthesized the composites of reduced graphene oxide and polypyrrole conducting polymer by in situ chemical polymerization by varying their mass ratio. The fabricated samples were characterized by FTIR spectroscopy, Raman spectroscopy, TEM, XPS, XRD, and cyclic voltammetry for further analyses for these nanostructures’ potential application in energy storage devices. Composite fabrication was verified through FTIR and Raman spectroscopy by confirming distinct peaks. TEM studies confirmed the presence of thin and randomly aggregated graphene oxide nanoparticles. XPS survey spectra identified carbon, nitrogen, and oxygen, with major peaks at 284 eV, 399 eV, and 531 eV, reflecting variations in C, N, and O. Cyclic voltammetry determined specific capacitance values of 4.66 F/g and 6.11 F/g for different mass ratios of polypyrrole and reduced graphene oxide.

用于高性能超级电容器应用的聚吡咯/还原氧化石墨烯复合材料的简易合成

超级电容器由于其高功率密度、快速充放电速率和长循环寿命而引起了人们的广泛关注。然而，为了进一步提高其性能，尖端电极材料的创造是必不可少的。由石墨烯基导电聚合物制成的纳米结构显示出了希望，因为它们结合了石墨烯和导电聚合物的特殊品质。本研究通过改变还原氧化石墨烯与聚吡咯导电聚合物的质量比，采用原位化学聚合的方法合成了还原氧化石墨烯与聚吡咯导电聚合物的复合材料。采用FTIR、拉曼光谱、TEM、XPS、XRD、循环伏安等方法对制备的样品进行表征，进一步分析了纳米结构在储能器件中的应用前景。通过红外光谱（FTIR）和拉曼光谱（Raman spectroscopy）证实了复合材料的制备。透射电镜研究证实了薄且随机聚集的氧化石墨烯纳米颗粒的存在。XPS调查光谱识别出碳、氮和氧，主要峰位于284 eV、399 eV和531 eV，反映了碳、氮和氧的变化。循环伏安法测定了不同质量比的聚吡咯和还原氧化石墨烯的比电容值分别为4.66 F/g和6.11 F/g。

期刊介绍： The Journal of Electronic Materials (JEM) reports monthly on the science and technology of electronic materials, while examining new applications for semiconductors, magnetic alloys, dielectrics, nanoscale materials, and photonic materials. The journal welcomes articles on methods for preparing and evaluating the chemical, physical, electronic, and optical properties of these materials. Specific areas of interest are materials for state-of-the-art transistors, nanotechnology, electronic packaging, detectors, emitters, metallization, superconductivity, and energy applications. Review papers on current topics enable individuals in the field of electronics to keep abreast of activities in areas peripheral to their own. JEM also selects papers from conferences such as the Electronic Materials Conference, the U.S. Workshop on the Physics and Chemistry of II-VI Materials, and the International Conference on Thermoelectrics. It benefits both specialists and non-specialists in the electronic materials field. A journal of The Minerals, Metals & Materials Society.
