Description

technical field

[0001] The present invention relates to an oil-water separation type composite airgel and a preparation method thereof, in particular to an oil-water separation type sodium alginate / graphene oxide composite airgel and a preparation method thereof, which has salt resistance, underwater super oleophobicity and The anti-oil pollution performance belongs to the technical field of preparation of biomass-based functional materials. Background technique

[0002] In the past few decades, oil spills and chemical spills have occurred frequently, causing great harm to the marine environment and ecosystems. Therefore, how to achieve efficient oil-water separation in the marine environment has become a topic of global concern. Oil-water separation belongs to the field of interfaces, and the development of functional materials with superoleophobic properties is an effective and facile strategy to solve this problem. So far, materials with superoleophobic properties in ai...
