▎ 摘  要

NOVELTY - The film has a graphene oxide and carbon quantum dots in water is dispersed according to a certain ratio to form a composite suspension. The pH value of the composite suspension is adjusted to form a stable and dispersed carbon quantum dot-graphene oxide composite sheet suspension. Filtration is configured to form graphene oxide-quantum dot composite film. USE - Graphene oxide-carbon quantum dot composite hydrophilic and oleophobic film used in mining process. ADVANTAGE - The composite membrane of the film has high self-cleaning characteristics, has a simple preparation method, cheap and readily available raw materials, easy adjustment, and is beneficial to large-scale industrial production. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the graphene oxide-carbon quantum dot composite hydrophilic and oleophobic film.
