▎ 摘　　要

NOVELTY - A composite material based on multilayer graphene is mixture of multilayer graphene and activated carbon. The multilayer graphene is loaded on activated carbon by macromolecule material. USE - The composite material based on multilayer graphene is used for absorbing volatile organic compound (VOC) (claimed). ADVANTAGE - The material can be regenerated and reused under certain condition, realizes fast and high-efficient adsorption of low-concentration VOC, and solves problem that adsorbent has low indoor environment removing effect, incomplete and slow adsorption rate of low-concentration air pollutant. The method has simple preparation method and low cost, and does not generate secondary pollution. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing composite material based on multilayer graphene comprising dispersing multilayer graphene in polymer material solution to obtain multilayer graphene dispersion, placing activated carbon for 2-4 hours to obtain initial composite material, and activating at 100-150degrees Celsius for 2-4 hours under vacuum environment.
