Review of recent achievements in self-healing conductive materials and their applications

Self-healing materials have attracted increasing attention because of their wide range of applications. It can be expected to offer obvious advantages in conductive materials with self-healing properties, which are regarded as promising candidates for the fabrication of self-healing electronics, energy storage devices, sensors, anticorrosive coating and conductive adhesives. In this review, we focused on recent efforts to develop self-healing conductive composites including their preparation methods, properties and applications. The self-healing conductive materials were presented based on different conductive mediums, such as metal, carbon, conductive polymer, ionic liquids. In addition, their novel applications of the self-healing conductive materials in conductive coatings, energy storage devices and sensors are highlighted. Finally, the future challenges of conductive materials with self-healing properties are proposed.
