Synthesis and Properties of Self-healing Polymers and Electrically Conductive Composites Based on Hydrogen-bonding [PDF]
, 2015 通过模仿生物体自愈合的特性，人工合成可自行感知和修复损伤的聚合物材料是一项富有深远意义的研究。目前聚合物材料在加工和使用过程中容易受到各种外界因素的破坏并产生难以监测的微裂纹，而这些微裂纹正是材料性能退化的起点。作为一种新颖的智能仿生材料，自修复聚合物能够感知并修复这类损伤，避免材料受到进一步破坏，延长材料使用寿命，消除安全隐患，节约维修成本。然而，目前研究的自修复高分子材料大多为绝缘体，使得其在导电领域中的应用受到限制。随着导电高分子材料在电子器件、传感器、能源、信息、航空等领域的广泛应用 ...
