Abstract
A method for ultra-hydrophilic surface treatment of a polymer fiber substrate according to the present invention comprises the steps of: forming a thermosetting coating layer on the surface of a polymer substrate; forming a carboxylate group (—COO—) on the surface of the thermosetting coating layer; forming an amide bond (—CONH—) between the thermosetting coating layer and hydrogel monomers; and forming a hydrophilic polymer layer by crosslinking the hydrogel monomers.
Claims6
A filter for oil-water separation comprising a polymer fiber substrate, and a thermosetting coating layer and a hydrogel layer formed on the surface of the polymer fiber substrate,
- wherein the thermosetting coating layer and the hydrogel layer are bonded by forming acrylamide crosslink bond, and
- wherein the filter has a super-hydrophilicity with a contact angle to water in the air being 10° or less.
