A method of coating a surface of an article, comprising
- depositing a composition including an anchoring polymer on a surface, and
- depositing a first hydrophilic polymer and a second hydrophilic polymer on the composition including the anchoring polymer.
An article comprising a coated surface, the coating comprising:
- an anchoring layer in contact with the surface of the article, the anchoring layer including an anchoring polymer;
- a first layer over the anchoring layer, the first layer including a first hydrophilic polymer;
- and
- a second layer over the first layer, the second layer including a second hydrophilic polymer;
- wherein the coating is insoluble at physiological pH.
