导电自修复材料的研究进展

Research Progress of Conductive Self-healing Materials

导电高分子材料因具备良好的导电性、质轻和易加工特性而被广泛应用于航空、生物医学设备、化学生物传感器和能源等领域。然而,导电高分子材料在使用过程中不可避免地会产生微裂纹,从而破坏导电通路并使整个电子设备瘫痪。受生物体启发,设计和构筑具备自修复功能的导电高分子材料是研究的热点。本文介绍了导电自修复材料的最新研究动态,综述了自修复机理和材料的制备方法及应用前景,最后简要分析导电自修复材料目前存在的主要问题并展望其发展方向。

Conductive polymers are widely employed in aviation, biomedical equipment, chemical biosensor and energy field. However, the conductive polymers will inevitably produce micro-cracks in the course of usage, resulting in destroying conductive path and paralyzing the entire electronic device. The study of conductive self-healing materials, inspired by the self-repair of organism damage, has drawn great research interests. In this review, recent progress in the field of conductive self-healing materials was summarized, and the corresponding self-healing mechanism, preparation method and application were discussed thoroughly, and finally the main problems existing in conductive self-healing materials were briefly analyzed and the development direction was prospected.
