Abstract
The disclosure provides a surface-modified contact lens including a lens body, a first modification layer inside the lens body, and a second modification layer on a surface of the lens body, in which the first modification layer and the second modification layer are connected through the surface, the first modification layer and the second modification layer comprises a hydrophilic polymer, and a thickness of the first modification layer from the surface of the lens body is in a range of 1 nm to 100 nm.
Claims20
A surface-modified contact lens, comprising:
- a lens body;
- a first modification layer inside the lens body;
- and
- a second modification layer on a surface of the lens body, wherein the first modification layer and the second modification layer are connected through the surface, the first modification layer and the second modification layer comprise a hydrophilic polymer, and a thickness of the first modification layer from the surface of the lens body is in a range of 1 nm to 100 nm.
A method of preparing a surface-modified contact lens, comprising:
- immersing a lens body in a first solution comprising an organic free radical initiator having a charged structure or a hydrogen-bond donor, wherein the organic free radical initiator is absorbed by the lens body;
- transferring the lens body into a second solution comprising a hydrophilic monomer;
- and
- reacting the organic free radical initiator with the hydrophilic monomer to form a first modification layer inside the lens body and a second modification layer on a surface of the lens body, wherein the first modification layer and the second modification layer are connected through the surface.
A method of modifying a surface of a polymeric material, comprising:
- immersing the polymeric material in a first solution comprising an organic free radical initiator having a charged structure or a hydrogen-bond donor, wherein the organic free radical initiator is absorbed by the polymeric material;
- transferring the polymeric material into a second solution comprising a hydrophilic monomer;
- and
- reacting the organic free radical initiator with the hydrophilic monomer to form a first modification layer inside the polymeric material and a second modification layer on the surface of the polymeric material, wherein the first modification layer and the second modification layer are connected through the surface.
