The patent with the publication number CN103088227A reports a method of using ammonia water to treat the surface of foamed copper and absorbing stearic acid to prepare a surface-hydrophobic oil-water separation material. However, this method can only modify the relatively expensive foamed copper, and cannot The surface of the inert material is modified, and the application range is narrow
The patent with the publication number CN102698471A reports that polylactic acid is used to prepare a porous membrane and then surface-modify it to obtain a degradable oil-water separation membrane with hydrophobic properties. Although this material exhibits strong hydrophobic properties, due to the polymer Due to its poor mechanical properties, its pressure bearing capacity is not high, which limits its application
The patent with the publication number of CN102953268A reported that the sol-gel method was used to graft hydrophobic silica sol on the surface of polyester fabrics. The preparation process of this method is complicated, and the price of the required raw material ethyl orthosilicate is relatively high, which is not conducive to popularization and use.
