Abstract
The present invention is directed to a method for the production of a durably hydrophilic, non-leaching coating. A carbohydrate-salt mixture is formed by at least partially dissolving a water insoluble carbohydrate in an aqueous salt solution to form a carbohydrate-salt complex. The carbohydrate-salt mixture is applied to a substrate, and the substrate is rinsed with a solvent to form a coating.
Claims44
A method of producing a coating, the method comprising:
- forming a carbohydrate-salt mixture by at least partially dissolving a water insoluble carbohydrate in an aqueous salt solution to form a carbohydrate-salt complex;
- adding water to the carbohydrate-salt mixture to form a diluted carbohydrate-salt mixture to control the orientation and degree of aggregation of the carbohydrate-salt complex;
- adding a surfactant to the diluted carbohydrate-salt mixture;
- applying the diluted carbohydrate-salt mixture to a substrate;
- and
- rinsing the substrate with water to form a regenerated carbohydrate coating.
