▎ 摘　　要

NOVELTY - A triphenylphosphine-based porous organic polymer and graphene aerogel composite, comprises reduced graphene oxides, aromatic diamine and tri-(4-formylphenyl) phosphine. The aromatic diamine contains p-benzidine, p-phenylenediamine and p-4,4'-diamino-p-terphenyl. USE - Triphenylphosphine-based porous organic polymer and graphene aerogel composite is used as anode material of supercapacitor. ADVANTAGE - The triphenylphosphine-based porous organic polymer and graphene aerogel composite provides supercapacitors with excellent electrochemical performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the preparation of triphenylphosphine-based porous organic polymer and graphene aerogel composite which involves adding reduced graphene oxides and aromatic diamine, solvent, ultrasonically stirring, adding acetic acid and tri - (4-formylphenyl) phosphine solution and continuously stirring to form suspension. The solvent is mixture of trimethylbenzene and 1, 4-dioxane or 2-methylpropan-2-ol and o-dichlorobenzene in the volume ratio of 1:3 - 3:1. The mol ratio of tri-(4-formyl phenyl) phosphine to aromatic diamine is 2: 3. The mass ratio of tri-(4-formyl phenyl) phosphine to reduced graphene oxides is 1:3 - 3:1. The reaction concentration of the tri-(4-formyl phenyl) phosphine in the turbid liquid is 0.005 - 0.05 mol/L. The concentration of acetic acid solution in the turbid liquid is 0.1-1 mol/L, freezing suspension liquid by liquid nitrogen, vacuumizing, unfreezing and sealing and leaving still, obtaining the crude product, filtering and washing with N, N-dimethyl formamide, extracting by tetrahydrofuran and vacuum drying.
