METHODS OF MATERIAL HYDROPHILIZATION BY SILOXANES CONTAINING NITRILOPOLY (METHYLENEPHOSPHONIC ACID) OR DERIVATIVES THEREOF

摘要

An article having a hydrophilic surface of a material, including a base material having a surface; and a siloxane oligomer represented by Chemical Formula 1 chemically affixed to the surface of the base material wherein the organosiloxane coating comprises a reaction product of a siloxane oligomer represented by Chemical Formula 1 or a polysiloxane derived therefrom, with a phosphonic acid compound represented by Chemical Formula 2:;;herein in Chemical Formula 1, R1, R2, and R3 are the same or different, and are each independently hydrogen or a C1 to C3 alkyl group, A is a single bond or a C1 to C5 alkylene group, and n ranges from 2 to 3;;GN[CH2PO3H2]2  Chemical Formula 2;wherein in Chemical Formula 2, G is —CH2PO3H2, a group represented by Chemical Formula 3, or a group represented by Chemical Formula 4 as described herein.

1. An article having a hydrophilically-modified surface, wherein the article comprises:
a base material; and an organosiloxane coating chemically fixed on a surface of the base material, wherein the organosiloxane coating comprises a reaction product of a siloxane oligomer represented by Chemical Formula 1 or a polysiloxane derived therefrom, with a phosphonic acid compound represented by Chemical Formula 2:wherein in Chemical Formula 1,
R1, R2, and R3 are the same or different, and are each independently hydrogen or a C1 to C3 alkyl group, A is a single bond or a C1 to C5 alkylene group, and n ranges from 2 to 30;
GN[CH2PO3H2]2  Chemical Formula 2wherein in Chemical Formula 2,
G is —CH2PO3H2, a group represented by Chemical Formula 3, or a group represented by Chemical Formula 4:wherein in Chemical Formula 3,
m is an integer ranging from 2 to 8; andwherein in Chemical Formula 4,
a and b are the same or different and are each independently integers ranging from 2 to 6.
