▎ 摘　　要

NOVELTY - The preparation of polymer/graphene foam material having electromagnetic shielding properties, involves dispersing graphene in organic solvent, adding polymer and dissolving to obtain mixed solution, pouring mixed solution into a scraper for coating and phase separation, drying to obtain polymer/graphene microfoamed film, laminating polymer/graphene microfoamed film with wave-transmitting material, and binding with glue to form sandwich structure. USE - Preparation of polymer/graphene foam material used in electromagnetic shielding application (all claimed). ADVANTAGE - The method enables preparation of polymer/graphene foam material with high electromagnetic shielding properties and wide application prospect. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) polymer/graphene foam material; and (2) usage of polymer/graphene foam material in electromagnetic shielding application.
