摘　　要：将原位聚合电解质单体N-羟甲基丙烯酰胺(NM)用于改性活性炭,考察其对炭材料结构组成和所构建固态超级电容器性能的综合影响。研究结果表明:NM可以在不破坏活性炭原始形貌结构的前提下,促进电解质前驱体溶液在所制备电极中的体相浸润,改善电极/固态电解质界面接触与相容性。同时,NM通过携带的羟基官能团还能够去除活性炭中的微量杂质,缓解界面副反应产生。相比改性前,活性炭经NM改性后具有更为优异的高压耐受能力,电极循环稳定性与功率特性均得到明显改善。In-situ polymerizable monomer N-methylolacrylamide(NM)was used to modify the activated carbon,and its influences on the structural composition of the carbon material and solid-state supercapacitor performances were investigated.Research results suggest that the introduction of the NM did not damage the original morphology and structure of activated carbon,but can promote the bulk phase infiltration of the electrolyte precursor solution in the prepared electrode,and improve the interface contact and compatibility between the active carbon electrode and in-situ polymerized solid-state electrolyte.Meanwhile,the NM carrying the hydroxyl functional group could remove trace amount of impurities in the activated carbon and thus alleviate the interface side reactions.Compared to the original counterpart,the NM-modified activated carbon delivers superior high-voltage tolerance,improved cycle stability and power characteristic.
