【摘要】 导电聚合物复合材料已广泛用于电学、电化学及能源储存设备的设计,而自修复材料则能够有效延长设备使用寿命,提高安全性及促进可持续性。本文利用原位聚合方法制备了一种具有良好自修复性能的聚合物/聚吡咯(MD/PPY)复合材料,该材料具有高的机械强度和良好的延展性。穿插在聚合物基体网状结构间的聚吡咯相互交联形成连续的电子传输通道,赋予材料以良好的导电性能。且由于聚吡咯的引入,抑制了聚合物在水溶液中溶胀性,使材料能够适用于多种工作环境。因此,该材料在制备自修复柔性导线及超级电容器等方面具有潜在的应用前景。更多还原

【Abstract】 Self-healing polymer composites with decent electrical properties, can significantly extend material’s lifespan, improve product safety, and ensure sustainability, are a promising class of polymeric materials for a range of technological applications, such as electrical, electrochemical, and energy storage devices. Here, one novel conductive polymer composite with superior self-healing properties is designed and fabricated through in-situ polymerization methods using commercial monomers and pyrrole. The continuous transporting path for electrons formed in the interpenetrating binary network structure enable the materials with excellent conductivity. The resultant materials with high mechanical strength can automatically repair the mechanical damage caused by deformation over time or accidental cutting. Combining with polypyrrole, the stability of the materials in water is greatly improved indicated that the materials could be used in diverse work environments. Thus, this kind of conductive polymer composite dominate their competition in stretchable self-healing conductive wires and supercapacitors.更多还原
