▎ 摘　　要

NOVELTY - An integrated carbon nanotube grafted graphene conductive composite material is a three-dimensional network structure, and nickel metal nanoparticles used as nodes to connect graphene and carbon nanotubes. USE - The integrated carbon nanotube grafted graphene conductive composite material is useful in conductive elastomer (claimed) used in stretchable electrode and flexible wearable equipment. ADVANTAGE - The integrated carbon nanotube grafted graphene conductive composite material has excellent conductivity, is simple, low in cost and environmentally-friendly, and can be prepared by a simple method, which uses inexpensive raw materials, and avoids the traditional oxidation-reduction method for preparing the strong acid waste liquid in process of graphene. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: preparation of the integrated carbon nanotube grafted graphene conductive composite material, which involves mixing glucose monohydrate, ammonium chloride and divalent nickel inorganic acid salt with deionized water, drying, grinding to obtain mixed powder, adding to a binary salt system comprising sodium chloride and potassium chloride, preheating, transferring the preheated material to a tubular furnace for heat-preservation under an argon atmosphere, then switching to an acetylene gas channel, continuously heat-preserving, then switching to an argon gas channel, cooling to room temperature, cleaning, and drying; and a conductive elastomer, which comprises an elastic polymer substrate containing the integrated carbon nanotube grafted graphene conductive composite material.
