Abstract：Toaddress theproblems of insufcient conductivityof carbon-based materials and limited charge transport of organic framework materials，the study proposed a design technology for DAAQ-COFs/GA composite aerogels.Through alkali-regulated surface charges，CTAB electrostatic modification，and hydrothermal self-assembly，molecular-level compounding of covalent organic frameworksand graphene was achieved.The results showed that the material had a specific surface area of 425.3m2/g and formed a hierarchical porous structure，with a specific capacitance of 378 F/g at 1 A/ g ;it retained 81.5% of the capacitance at 7O A/g and achieved a capacity retention rate of 87.8% after 20 OoO cycles，which was significantly superior to that of single components.This verified the enhancement efect of the“conductive network-active framework”synergistic mechanism on electrochemical performance.
