A conducting polymer-based hydrogel (PPy/CPH) with a polypyrrole–poly(vinyl alcohol) interpenetrating network was prepared by utilization of a chemical cross-linked poly(vinyl alcohol)–H2SO4 hydrogel (CPH) film as flexible substrate followed by vapor-phase polymerization of pyrrole. Then an all-solid-state polymer supercapacitor (ASSPS) was fabricated by sandwiching the CPH film between two pieces of the PPy/CPH film. The ASSPS is mechanically robust and flexible with a tensile strength of 20.83 MPa and a break elongation of 377% which is superior to other flexible conducting polymer hydrogel-based supercapacitors owing to the strong hydrogen bonding interactions among the layers and the high mechanical properties of the PPy/CPH. It exhibits maximum volumetric specific capacitance of 13.06 F/cm3 and energy density of 1160.9 μWh/cm3. The specific capacitance maintains 97.9% and 86.3% of its initial value after 10 000 folding cycles and 10 000 charge–discharge cycles, respectively. The remarkable electrochemical and mechanical performance indicates this novel ASSPS device is promising for flexible electronics.

基于聚吡咯水凝胶的高机械柔性全固态聚合物超级电容器的设计与制造
利用化学交联的聚乙烯醇-H 2 SO 4制备了具有聚吡咯-聚乙烯醇互穿网络的导电聚合物基水凝胶（PPy / CPH）。将水凝胶（CPH）膜作为柔性基材，然后进行吡咯的气相聚合。然后，通过将CPH膜夹在两片PPy / CPH膜之间来制造全固态聚合物超级电容器（ASSPS）。ASSPS具有强大的机械强度和柔韧性，抗拉强度为20.83 MPa，断裂伸长率为377％，由于各层之间的强氢键相互作用和高机械性能，优于其他基于柔性导电聚合物水凝胶的超级电容器。 PPy / CPH。它具有13.06 F / cm 3的最大体积比电容和1160.9μWh/ cm 3的能量密度。在1万次折叠和1万次充放电循环后，比电容分别保持其初始值的97.9％和86.3％。出色的电化学和机械性能表明，这种新颖的ASSPS器件有望用于柔性电子产品。
