Hydrophilic material and method of manufacturing the same.

摘要

A hydrophilic material having excellent hydrophilicity and fitness to living bodies and used for porous membranes or the like and also a method of manufacturing the same. The hydrophilic material is formed by subjecting at least part of the surfaces (1a) of a substrate (1) of a polymer material to a plasma treatment to thereby produce a polymer radical and graft polymerizing therewith a block copolymer containing a hydrophilic monomer (2) supplied in the gasious phase and a subsequently supplied hydrophobic monomer (3).
