Abstract

The present invention relates to a method to prepare polymer woven fabric surface with selective oleophilicity or hydrophobicity and oil-oil separation and oil-water separation filter prepared by using the surface. The method to prepare the surface with selective oleophilicity or hydrophobicity according to the present invention includes steps comprising a step to form nano meter sized pores on the surface of the polymer woven fabric surface with micro sized pores through drying type etching; and a step to form selective oleophobic or hydrophobic film on the nano meter sized pores. It is possible to control hydrophobic/oleophobic property according to pore size, material or thickness of the film and this polymer surface with hybrid pores can be used in various areas such as an oil filter for car capable of selective separation of oil-oil mixture and water-oil mixture, disposal of waste oil, treatment of marine oil leakage, and pretreatment of crude oil refinement.
