Abstract

Carbon-based materials, particularly graphite, have been extensively studied for their potential in fabricating flexible conductive fabrics with high electrical conductivity, which are attractive for wearable electronics. In this study, we investigated the effects of polar solvents, graphite concentration, and temperature on the electrical properties of conductive cotton fabrics. Our results show that the type of polar solvent and graphite concentration strongly influence the electrical conductivity of the fabrics. By controlling the graphite concentration, a wide range of conductive cotton fabrics with different conductivity values can be produced. Additionally, temperature resistance studies revealed that the fabrics exhibit both semiconductor and metallic behavior in the temperature range from room temperature to 160 °C. These interesting properties make the conductive cotton fabrics suitable for use as electrical components in circuits with resistive and inductive loads. Furthermore, we fabricated a supercapacitor with electrodes based on dispersed graphite and an electrolyte of sodium chloride salt dissolved in deionized water. Our findings suggest that conductive cotton fabrics have great potential for use in high-performance wearable electronics and energy storage devices.

革新电容器技术：基于石墨的导电棉织物作为超级电容器电容器

碳基材料，尤其是石墨，因其在制造具有高导电性的柔性导电织物方面的潜力而受到广泛研究，这种织物对可穿戴电子设备很有吸引力。在本研究中，我们研究了极性溶剂、石墨浓度和温度对导电棉织物电气性能的影响。结果表明，极性溶剂的类型和石墨浓度对织物的导电性有很大影响。通过控制石墨浓度，可以生产出多种不同导电率的导电棉织物。此外，耐温性研究表明，导电棉织物在室温至 160 °C 的温度范围内同时表现出半导体和金属特性。这些有趣的特性使导电棉织物适合用作带电阻和电感负载电路中的电气元件。此外，我们还制作了一种超级电容器，其电极基于分散石墨和溶解在去离子水中的氯化钠电解质。我们的研究结果表明，导电棉织物在高性能可穿戴电子设备和储能设备中具有巨大的应用潜力。

期刊介绍： Carbon Letters aims to be a comprehensive journal with complete coverage of carbon materials and carbon-rich molecules. These materials range from, but are not limited to, diamond and graphite through chars, semicokes, mesophase substances, carbon fibers, carbon nanotubes, graphenes, carbon blacks, activated carbons, pyrolytic carbons, glass-like carbons, etc. Papers on the secondary production of new carbon and composite materials from the above mentioned various carbons are within the scope of the journal. Papers on organic substances, including coals, will be considered only if the research has close relation to the resulting carbon materials. Carbon Letters also seeks to keep abreast of new developments in their specialist fields and to unite in finding alternative energy solutions to current issues such as the greenhouse effect and the depletion of the ozone layer. The renewable energy basics, energy storage and conversion, solar energy, wind energy, water energy, nuclear energy, biomass energy, hydrogen production technology, and other clean energy technologies are also within the scope of the journal. Carbon Letters invites original reports of fundamental research in all branches of the theory and practice of carbon science and technology.
