The important breakthrough mouthful of water separation technology development, compared with traditional water-oil separating material, the water-oil separating with special wellability
Material has high efficiency and high selectivity.At present, the water-oil separating material with special wellability mainly includes oil removing and water removal
Two classes.Using super-hydrophobic special wetability, can make that oil is passed through and water does not pass through completely, be mixed so as to efficiently separate profit
Compound, has many researchs to be applied to water-oil separating by super-hydrophobic so far, Chinese patent CN1387932A, CN1721030A,
Disclosed in CN101518695A and CN101708384A with super-hydrophobic oil-water separation mesh film and its system with super oleophylic function
Preparation Method.Equally, using super hydrophilic special wetability, can make that water is passed through and oil does not pass through completely, realize that profit is mixed
Compound is efficiently separated, and Chinese patent CN105413236A, CN102974226A, CN105056770A, CN103893999A are public
Open with super hydrophilic with the oil-water separation mesh film of superoleophobic function and preparation method thereof.
Selection versatile material, process simplification improves stability, reduces cost, realizes the big rule of water-oil separating material
The developing direction of mould preparation and application water-oil separating field.Compared with metal nethike embrane or other hard materials, paper base material has
It is soft, the advantages of easily shape, there is unique advantage for the preparation of water-oil separating material, but be prepared by base material with paper products
The report that super hydrophobic material is used for water-oil separating is few.(the ACS Appl.Mater.Interfaces., 2010,2,677- such as Lu
683) Nano particles of silicon dioxide is sticked into ordinary filter paper surface, the super-hydrophobic/super-oleophilic filter paper of preparation using polystyrene
The greasy dirt of floating on water can be removed, but nano-particle is sticked into its surface using polymer, it is molten in some organic solvents
Polymer is unstable in liquid, easily causes nano-particle and comes off, and influences its separative efficiency and Reusability.Chinese patent
