▎ 摘　　要

NOVELTY - Composite material comprises molybdenum disulfide/reduced graphene oxide three-dimensional composite material and polyether ether ketone (PEEK). USE - The composite material is useful for preparing a total heat exchanger in fresh air purifier or air purifier (claimed). ADVANTAGE - The composite material: has high wear resistance and high thermal conductivity; and is simple to prepare. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the composite material comprising (1) dispersing graphene oxide to obtain graphene oxide dispersion liquid; mixing molybdenum source and the sulfur source with graphene oxide dispersion liquid to perform hydrothermal reaction to obtain molybdenum disulfide/reduced graphene oxide three-dimensional composite material; and (2) mixing the pretreated PEEK with the molybdenum disulfide/reduced graphene oxide three-dimensional composite material obtained in step (1), granulating, cold pressing and sintering to obtain PEEK/MoS2/reduced graphene oxide composite material.
