NOVELTY - Preparation of nickel 2,3,6,7,10,11-hexaiminotriphenylene/graphene-based composite aerogel involves weighing graphene oxide, adding deionized water, stirring and dispersing to obtain a graphene oxide dispersion (A), weighing dispersed nickel 2,3,6,7,10,11-hexaiminotriphenylene powder (A) in acetonitrile, ultrasonically dispersing to obtain nickel 2,3,6,7,10,11-hexaiminotriphenylene dispersion (B), adding the dispersion (A) into the dispersion (B), adding aqueous ammonia, ultrasonically dispersing, magnetically stirring to obtain a mixed solution, transferring the mixed solution to a lined reaction kettle, placing in a heating furnace, hydrothermally reacting in the heating furnace to obtain composite hydrogel product, washing the obtained product with water, dialyzing, pre-freezing, freezing, and drying. USE - Preparation of nickel 2,3,6,7,10,11-hexaiminotriphenylene/graphene-based composite aerogel used in electrode material of supercapacitor (all claimed). ADVANTAGE - The method provides composite aerogel having excellent charge transmission performance and conductivity, and provides supercapacitor electrode material having excellent electrochemical performance.
