▎ 摘　　要

NOVELTY - The filter has a silane coupling agent hydrolyzed in an aqueous ethanol solution. A ceramic filter is impregnated with a modified graphene oxide to modify a surface of the graphene oxide. A ceramic filter is impregnated with the modified graphene oxide ethanol solution. 3-glycidyloxyproply trimethoxysilane (GPTMS) is used as the silane binding agent. The graphene oxide is coated on the ceramic filter, and is reduced to form a hydrophobic and conductive structure. A reducing agent is added to distilled water at a ratio of 1/100. A graphene oxide-coated ceramic filter part is put into a solution. USE - Graphene ceramic composite filter for simultaneous removal of ultrafine dust and harmful gases. ADVANTAGE - The graphene ceramic composite filter has excellent heat resistance and chemical resistance. DESCRIPTION OF DRAWING(S) - The drawing shows an electron microscope observation image of ceramics A and B of a graphene ceramic composite filter for simultaneous removal of ultrafine dust and harmful gases.
