HYDROPHILIZATION-TREATED SUBSTRATE AND METHOD FOR PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a hydrophilization-treated substrate by which a hydrophobic material can be coated with a hydrophilic polymer without unevenness.

SOLUTION: The method for producing the hydrophilization-treated substrate comprises (1) a step of dipping the hydrophobic material in a coating solution containing the hydrophilic polymer dissolved therein and (2) a step of taking out the hydrophobic material from the interior of the coating solution and dipping the hydrophobic material in an insoluble solution of the hydrophilic polymer before completely drying the coating solution. In the method for the production, the hydrophobic material has a plurality of through-hole micropores and is a polyolefin resin. The hydrophilic polymer is a polyamide.
