It is a challenge to realize high strength, toughness, and energy storage, as well as excellent capacitive self-recovery, fatigue-resistant, and self-healing performances simultaneously in a single all-in-one supercapacitor aiming for wearable electronics. Herein, based on the self-crosslinking and molecular template, a supramolecular poly(vinyl alcohol)/poly (N-hydroxyethyl acrylamide) (PVA/PHEA) hydrogel electrolyte (HGE) decorated by polyaniline (PANI) was prepared by in situ rapid polymerization of high-concentration aniline on the PVA/PHEA gel containing H2SO4. The multiple hydrogen bonds, rapid polymerization, and decoration endowed PANI-decorated PVA/PHEA HGE-based all-in-one flexible supercapacitor with the integrated high performances, which include high specific capacitance, good cycling stability, high strength, excellent toughness, rapid self-recovery, excellent fatigue-resistant, and self-healing capabilities, as well as high capacitance retention during or after the large deformations or after the self-healing. Thus, the current work presents a novel and promising strategy to design the integrated high-performance supercapacitors aiming for wearable electronics.

聚苯胺修饰的超分子水凝胶具有坚韧，抗疲劳和自愈性能，适用于多合一柔性超级电容器。
在面向穿戴式电子设备的单一多合一超级电容器中，同时实现高强度，韧性和能量存储以及出色的电容自恢复，抗疲劳和自修复性能是一项挑战。在此，基于自交联和分子模板，通过原位快速聚合制备由聚苯胺（PANI）修饰的超分子聚（乙烯醇）/聚（N-羟乙基丙烯酰胺）（PVA / PHEA）水凝胶电解质（HGE）。高浓度苯胺在含H2SO4的PVA / PHEA凝胶上的分离 多重氢键，快速聚合和修饰赋予了PANI装饰的PVA / PHEA HGE基多合一柔性超级电容器的综合性能，包括高比电容，良好的循环稳定性，高强度，优异的韧性，快速的自我恢复，出色的抗疲劳和自我修复能力，以及在大变形期间或之后或自我修复之后的高电容保持率。因此，当前的工作提出了一种新颖而有前途的策略，以设计针对可穿戴电子设备的集成高性能超级电容器。
