▎ 摘  要

NOVELTY - The preparation method of porous graphene composite material involves adding nano-graphene and polydimethylsiloxane to a muffle furnace and then heating at 230-240 degrees C for 60-80 minutes, adding sodium chloride to the mixture and then stirring for 30-40 minutes, dispersing the mixture in PVC solution and then filtering, ball milling the filtrate, adding distilled water to the mixture and then stirring at 500-600 rpm for 4-5 hours, refrigerating the mixture at -20 degrees C to 18 degrees C for 8-12 hours, and freeze-drying for 12-24 hours. USE - The method is useful for preparation of porous graphene composite material (claimed). ADVANTAGE - The method enables preparation of porous graphene composite material with high yield and excellent hydrophobicity.
