Claim Text:
1. A method of imparting hydrophilicity to a surface of a material, which comprises: providing a base material comprising a surface; applying and chemically fixing a siloxane oligomer represented by Chemical Formula 1 to the surface of the base material to form a siloxane-modified surface; and applying a glycidol compound represented by Chemical Formula 2 to the siloxane-modified surface and carrying out a reaction therebetween to form an organosiloxane coating comprising a N,N-bis(hydroxyalkyl)aminoalkyl group: wherein in Chemical Formula 1, R A is a single bond or a C1 to C5 alkylene group, and n ranges from 2 to 30; wherein in Chemical Formula 2, each R is the same or different, and is independently hydrogen, a C1 to C3 alkyl group, or a C1 to C3 hydroxyalkyl group, and L is a substituted or unsubstituted C1 to C3 alkylene group.
