Abstract
Provided is a hydrophilic coating composition, and more particularly, a hydrophilic coating composition including both a block copolymer and a random copolymer, each including repeating units of particular structures, wherein the hydrophilic coating composition may impart a hydrophilic property to the surface of a substrate when applied to the surface, while having excellent adhesiveness to the substrate.
Claims18
A hydrophilic coating composition, comprising:
- a block copolymer including a first repeating unit represented by the following Formula 1 and a second repeating unit represented by the following Formula 2;
- and
- a random copolymer including the first repeating unit represented by the following Formula 1 and the second repeating unit represented by the following Formula 2:
- wherein, in Formula 1, R1 is hydrogen or a hydrocarbyl group having 1 to 10 carbon atoms, X1 is oxygen or a bivalent amine group (—NR′—), wherein R′ is hydrogen or a hydrocarbyl group having 1 to 10 carbon atoms, and
- R2 is a zwitterionic group,
- wherein, in Formula 2, R3 is hydrogen or a hydrocarbyl group having 1 to 10 carbon atoms, X2 is oxygen or a bivalent amine group (—NR″—), wherein R″ is hydrogen or a hydrocarbyl group having 1 to 10 carbon atoms, and
- R4 is a silane moiety.
