▎ 摘  要

NOVELTY - Pressure-sensitive composite material comprises a three-dimensional graphene framework and a polymer attached to a three-dimensional graphene framework. The polymer is an aqueous polymer, which comprises 2-chlorobutadiene, styrene-acrylate emulsion or styrene-butadiene emulsion, and the mass ratio of the graphene framework and the polymer is 1: (1 to 9). USE - Pressure-sensitive composite material. ADVANTAGE - The pressure-sensitive composite material has improved conductivity with excellent pressure sensitivity, uses less reagents, has simple preparation process, low cost, and is easy to industrialize with expansion of production. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for producing pressure-sensitive composite material, which involves: (A) putting the graphene oxide in water, stirring and ultrasonicating to obtain the graphene oxide solution and placing it in a reaction kettle for hydrothermal reaction to obtain a three-dimensional graphene framework; and (B) immersing three-dimensional graphene framework in the polymer emulsion for a period of time, and then taking out and vacuum-drying to obtain the pressure-sensitive composite material.
