摘要

Abstract

Flexible electronic devices based on reversible bonds for self-curing capabilities arouses extensive interest. However

most of the composite conductive elastomers have the problems of poor mechanical properties and slow recovery of mechanical properties during multiple stretching

which hinder their stability in continuous operation. In this study

hyperbranched-MWCNTs/hyperbranched-PDMS self-healable conductive elastomers inspired by cephalopods were successfully developed. The prepared conductive elastomer exhibited good self-healing ability (91%) at room temperature excited by multiple reversible interactions. The prepared elastomer showed outstanding mechanical properties and anti-fatigue ability

so that it can cope with more arduous tasks. Moreover

the elastomer was sensitive to the change of stress states and can be used as a stable strain sensor. Therefore

the self-repairing conductive elastomer has potential practicability in the fields of human-computer interaction

motion monitoring

soft robot and so on.
