Abstract
A zwitterionic resin is manufactured by a manufacturing method which includes the following steps. A first thermal process is performed on a first crosslinking agent and a choline having hydroxyl group or amino group to form a first mixture, in which the first crosslinking agent includes an isocyanate group. A second thermal process is performed on the first mixture, a second crosslinking agent, a chain extender, and an amino acid to form the zwitterionic resin, in which the chain extender includes a polyol.
Claims7
A manufacturing method of a zwitterionic resin, comprising:
- performing a first thermal process on a first crosslinking agent and a choline having hydroxyl group or amino group, such that a first mixture is formed, wherein the first crosslinking agent comprises an isocyanate group, wherein the choline having hydroxyl group or amino group comprises a chemical structure represented by formula (3) or formula (4),
- wherein X− represents Cl−, OH−, or a tartaric group;
- and
- performing a second thermal process on the first mixture, a second crosslinking agent, a chain extender, and an amino acid, such that the zwitterionic resin is formed, wherein the chain extender comprises a polyol.
