NOVELTY - Preparing graphene/sodium carboxymethyl cellulose composite material with high dielectric loss involves uniformly stirring the graphene slurry, adding sodium carboxymethyl cellulose into the uniformly stirred graphene slurry and continuously stirring, carrying out vacuum freezing treatment to the uniformly stirred composite material, performing vacuum degreasing treatment to the vacuum frozen composite material and performing high temperature graphitization treatment to the vacuum degreased composite material. USE - Method for preparing graphene/sodium carboxymethyl cellulose composite material with high dielectric loss used in electronic communication and radar search. ADVANTAGE - The method provides graphene/sodium carboxymethyl cellulose composite material with high dielectric loss. The method is simple and easy to realize.
