Membrane surface modification method to make hydrophobic and Hydrophobic Membrane manufactured using thereof

摘要

The present invention is characterized in that an ultraviolet (UV) light-curable polymer solution (20) having a polyurethane acrylate and an initiator inside the surface of the hydrophilic separation membrane (10) and a cavity is first cured by ultraviolet Wherein the water-repellent material (30) is further coated on the surface of the coated surface through the surface and voids to form a hydrophobic surface modification method of the hydrophilic separation membrane, and a membrane- Thereby providing a suitable hydrophobic separation membrane.
