METHOD FOR THE FORMATION OF HYDROGEL MULTILAYERS THROUGH SURFACE INITIATED PHOTOPOLYMERIZATION

摘要

Multiple-layer hydrogels and methods of forming hydrogels having multiple layers are disclosed. The hydrogels are formed of prepolymerization solutions comprising monomers or macromers, particularly polyethylene glycol. The layers are covalently bonded, and the hydrogels may comprise two or more layers.
