NOVELTY - Phosphaalkene-graphene composite material is porous foam material, which is obtained by combining phosphaalkene and graphene composite. USE - Phosphaalkene-graphene composite material. ADVANTAGE - The phosphaalkene-graphene composite material enables to prepare in simple manner, has good electric conductivity, thermal conductivity, stability and flexible, large specific surface area, good mechanical performance, high yield, good product quality, easy operation and low requirement of equipment. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing phosphaalkene-graphene composite material, which involves: (A) adding the phosphaalkene and graphite oxide in the vacuum ball mill; (B) adding the dispersion liquid to obtain mixed suspension of phosphaalkene and graphite oxide; (C) soaking the porous matrix in the obtained mixed suspension and volatilizing under protective gas; (D) heating to 500-1100 degrees C for 1-48 hours to obtain phosphaalkene-graphene composite material precursor; and (E) soaking in acidic liquid to remove the porous matrix to obtain phosphaalkene-graphene composite material.
