Polyaniline has been widely used in high-performance pseudocapacitors, due to its low cost, easy synthesis, and high theoretical specific capacitance. However, the poor mechanical properties of polyaniline restrict its further development. Compared with polyaniline, functionalized carbon materials have excellent physical and chemical properties, such as porous structures, excellent specific surface area, good conductivity, and accessibility to active sites. However, it should not be neglected that the specific capacity of carbon materials is usually unsatisfactory. There is an effective strategy to combine carbon materials with polyaniline by a hybridization approach to achieve a positive synergistic effect. After that, the energy storage performance of carbon/polyaniline hybridization material has been significantly improved, making it a promising and important electrode material for supercapacitors. To date, significant progress has been made in the synthesis of various carbon/polyaniline binary composite electrode materials. In this review, the corresponding properties and applications of polyaniline and carbon hybrid materials in the energy storage field are briefly reviewed. According to the classification of different types of functionalized carbon materials, this article focuses on the recent progress in carbon/polyaniline hybrid materials, and further analyzes their corresponding properties to provide guidance for the design, synthesis, and component optimization for high-performance supercapacitors.
聚苯胺由于其低成本、易合成和高理论比电容而被广泛应用于高性能赝电容器中。然而，聚苯胺的机械性能较差限制了其进一步的发展。与聚苯胺相比，功能化碳材料具有优异的物理和化学性质，如多孔结构、优异的比表面积、良好的导电性和可及的活性位。然而，不应忽视的是，碳材料的比容量通常不能令人满意。通过杂化方法将碳材料与聚苯胺结合是一种有效的策略，可以实现正协同效应。此后，碳/聚苯胺杂化材料的储能性能得到了显著提高，使其成为超级电容器有前途和重要的电极材料。迄今为止，在合成各种碳/聚苯胺二元复合电极材料方面已经取得了重大进展。在这篇综述中，简要回顾了聚苯胺和碳杂化材料在储能领域的相应性质和应用。根据不同类型功能化碳材料的分类，本文重点介绍了碳/聚苯胺杂化材料的最新进展，并进一步分析了它们的相应性质，为高性能超级电容器的设计、合成和组件优化提供了指导。
