Abstract

The present disclosure provides a coated structure for forming a hydrophilic film on a surface. The coated structure includes a carrier substrate and a superhydrophilic material layer. The carrier board has a surface, and the superhydrophilic material layer is coated on the surface of the carrier board. The superhydrophilic material layer is composed of a zwitterionic compound having a chemical formula of (I):

wherein R1 and R2 are individually hydrogen or a C1-C5 alkyl group, and n is an integer of 1-20. A method for antifouling treatment using a coated layer and a method for fouling-resistant treatment using a coated layer are also provided herein.

First claim

What is claimed is:

1 . A coated structure for forming a hydrophilic film on a surface, comprising:
a carrier board having a surface; and a superhydrophilic material layer coated on the surface of the carrier board, the superhydrophilic material layer comprising a zwitterionic compound having a structure of chemical formula I:

wherein R 1 and R 2 are individually hydrogen (H), methyl group (—CH 3 ), ethyl group (—C 2 H 5 ) or propyl group (—C 3 H 7 ), and n is an integer of 1-20.

2 . The coated structure of claim 1 , wherein a material of the carrier board comprises metal selected from the group consisting of silver, gold, copper, iridium, nickel, germanium, mercury, palladium, ruthenium, zinc, iron, barium, yttrium, gallium, cadmium, indium and a combination thereof.

3 . The coated structure of claim 1 , wherein a material of the carrier board comprises metal selected from the group consisting of mercury telluride (HgTe), cadmium telluride (CdTe), cadmium sulfide (CdS), silver sulfide (AgS), palladium sulfide (PdS), zinc sulfide (ZnS), gallium arsenide (GaAs), indium phosphide (InP), yttrium barium copper oxide (YBaCuO x ) and a combination thereof.

4 . The coated structure of claim 1 , wherein a material of the carrier board comprises stainless steel.

5 . The coated structure of claim 1 , wherein the zwitterionic compound has a structure of chemical formula II:

6 . The coated structure of claim 1 , wherein the zwitterionic compound has a structure of chemical formula III:

7 . The coating structure of claim 1 , wherein the zwitterionic compound is adsorbed on the carrier board by a thiol group (—SH).

8 . The coating structure of claim 1 , wherein a coating density of the zwitterionic compound on the carrier board is greater than or equal to 15 ng/cm 2 .

9 . The coating structure of claim 1 , wherein a coating density of the zwitterionic compound on the carrier board is greater than or equal to 30 ng/cm 2 .

10 . A method for antifouling treatment using a coated structure, the coated structure comprising:
a carrier board having a surface; and the superhydrophilic material layer of claim 1 coated on the surface of the carrier board.

11 . A method for fouling-resistant treatment using a coated structure, the coated structure comprising:
a carrier board having a surface; and the superhydrophilic material layer of claim 1 coated on the surface of the carrier board.
