高分子导电材料既具有金属的导电性又具有有机材料般的柔顺可加工性,在军事、能源、生物化学传感器等方面应用广泛。然而,其在制造使用过程中一旦发生破坏,就会造成电气元件的性能故障,甚至造成整个系统的瘫痪和报废。自愈合是人们模仿生物体损伤愈合的概念,解决材料损伤,延长材料使用寿命的新方法。本文综述了自愈合导电材料研究领域的最新动态,讨论了自愈合的机理和材料的制备方法,最后介绍了导电自愈合材料在超级电容器和电传感等方面的应用前景。我们相信导电自愈合材料的理论和应用研究会进一步推动电子器件领域的快速发展。
Polymer conductive material not only has the conductivity of metal but also has the organic material like soft workability, in the military, energy, biochemical sensors and so on. However, once it is destroyed in the process of manufacture and use, it will cause the performance failure of the electrical components and even cause the entire system to be paralyzed and scrapped. Self-healing is a new way of people to imitate the concept of organism wound healing, to solve the material damage and prolong the service life of the material. This review summarizes the recent developments in the field of self-healing conductive materials, discusses the mechanism of self-healing and the preparation of materials, and finally introduces the application prospects of conductive self-healing materials in supercapacitors and electrical sensing. We believe that the theory and application of conductive self-healing materials will further promote the rapid development of electronic devices.
