摘要:以聚丙烯酰胺链交联形成三维网状结构,通过大豆蛋白纳米粒子与聚丙烯酰胺之间的静电引力,将大豆蛋白引入聚丙烯酰胺交联网络中,经磷酸溶液置换,得到一种水凝胶电解质。大豆蛋白纳米粒子与聚丙烯酰胺分子链之间的协同作用,使得水凝胶在80%应变时进行100次的循环压缩后未发生结构断裂或损坏;以水凝胶电解质为固体电解质,以聚吡咯-碳纳米管纸为电极,组装成对称结构的全固态超级电容器。组装的全固态超级电容器具有优异的电化学性能,最大能量密度为6.2 W·h/kg,最大功率密度为398.4 W/kg。更重要的是,器件整体可承受80%的压缩应变而未产生断裂或损坏,并表现出良好的电容稳定性.
A hydrogel electrolyte was developed,in which polyacrylamide(PAAm)chains were cross-linked to form network structure,soybean protein(SPI)nanoparticles were coagulated around the polymer chains,and phosphoric acid(H3PO4)was incorporated by displacement.The synergistic effect of SPI nanoparticles and PAAm chains makes that the hydrogel electrolyte could maintain structural integrity even after 100 compression cycles at 80%strain;a symmetric all-solid-state supercapacitor was then assembled by using the hydrogel electrolyte as solid electrolyte and two identical polypyrrole-carbon nanotubes papers(PPy-CNTs)as electrode.The assembled supercapacitor possesses excellent electrochemical performance,delivering the maximum energy density of 6.2 W·h/kg and the maximal power density of 398.4 W/kg,which places in the region of standard supercapacitors.More importantly,the device could endure 80%compression strain without fracture or damage,and remain the high capacitance retention,showing a good capacitive stability.
