▎ 摘　　要

NOVELTY - Carbon/polymer based electromagnetic shielding material is claimed. The electromagnetic shielding material is prepared by melting graphene microchips and loading on polylactide to obtain carbon/polymer-based electromagnetic shielding material having graphene microchip content of 12-15 wt.%. USE - Used as carbon/polymer based electromagnetic shielding material. ADVANTAGE - The method has simple process, and is easy to perform. The electromagnetic shielding material has improved electromagnetic performance and electromagnetic shielding performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the carbon/polymer-based electromagnetic shielding material, comprising (i) drying graphene microchips and polylactide at 80 degrees C for 12 hours, and (ii) adding the dried graphene microchips and polylactide into a internal mixer, and mixing for 10-20 minutes to obtain final product.
