Abstract:
1. A method of grafting a polyurethane layer to a hydrogel layer the method comprising the steps of: providing a first solution comprising either reactive hydrogel or end-functionalized polyurethane precursors; applying a second solution to the first solution wherein the second solution comprises end-functionalized polyurethane precursors if the first solution comprises hydrogel precursors and wherein the second solution comprises reactive hydrogel precursors if the first solution comprises polyurethane precursors; and polymerizing and crosslinking the solutions to form a laminated graft polymer comprising a polyurethane layer and a hydrogel layer.
