▎ 摘　　要

NOVELTY - A chitosan solution is dripped to aqueous solution of graphene oxide, stirred and precipitated, to obtain graphene oxide-chitosan dispersion. The graphene oxide-chitosan dispersion is ultrasonically processed, and alkali solution is added, to obtain uniform graphene oxide-chitosan dispersion solution. The dispersion solution is vacuum filtered, evaporation-induced self-assembled and regulated, to obtain bionic stratiform high-toughness integrated electroconductive graphene composite material. USE - Preparation of bionic stratiform high-toughness integrated electroconductive graphene composite material used for capacitor electrode, and aerospace and tissue engineering applications. ADVANTAGE - The method enables preparation of bionic stratiform integrated electroconductive graphene composite material having excellent tensile strength, mechanical strength, resilience characteristics, electroconductivity and toughness. DETAILED DESCRIPTION - A chitosan solution is dripped to aqueous solution of graphene oxide, stirred and precipitated, to obtain graphene oxide-chitosan dispersion. The graphene oxide-chitosan dispersion is ultrasonically processed, and predetermined amount of alkali solution is added, to obtain uniform graphene oxide-chitosan dispersion solution. The uniform graphene oxide-chitosan dispersion solution is vacuum filtered and evaporation-induced self-assembled, to obtain crosslinked layered graphene oxide composite. The crosslinked layered graphene oxide composite is regulated, to obtain bionic stratiform high-toughness integrated electroconductive graphene composite material.
