A crosslinked membrane based on renewable, degradable and environmentally friendly soybean protein isolate was formed by solution casting method. A series of gel polymer electrolytes were prepared with the crosslinked membranes saturated with 1 mol·L LiSO. The solid-state electric double-layer capacitors were fabricated with the prepared gel polymer electrolytes and activated carbon electrodes. The optimized solid-state supercapacitor delivered a single electrode specific capacitance of 115.17 F·g at a current density of 1.0 A·g, which was higher than the supercapacitor assembled with the commercial separator in 1 mol·L LiSO. The solid-state supercapacitor exhibited an outstanding cycling stability, indicating that the gel polymer electrolyte based on the crosslinked soybean protein isolate membrane could be a promising separator for a solid-state supercapacitor.
通过溶液浇铸法制备了一种基于可再生、可降解且环境友好的大豆分离蛋白的交联膜。用1 mol·L LiSO饱和的交联膜制备了一系列凝胶聚合物电解质。用制备的凝胶聚合物电解质和活性炭电极制造了固态双电层电容器。优化后的固态超级电容器在电流密度为1.0 A·g时的单电极比电容为115.17 F·g，高于在1 mol·L LiSO中用商业隔膜组装的超级电容器。该固态超级电容器表现出优异的循环稳定性，表明基于交联大豆分离蛋白膜的凝胶聚合物电解质可能是一种有前途的固态超级电容器隔膜。
