Abstract
Described herein is a method for coating an object with a polymer layer. The method includes contacting the object with a first solution comprising a non-polymeric grafting initiator comprising at least one photoinitiator group capable of generating a free radical active species upon absorption of electromagnetic energy, wherein the photoinitiator group is selected from the group consisting of an initiator that is insoluble in polar solvent; and a negatively charged initiator; irradiating the first solution and the object, resulting in the grafting initiator binding to the object; removing the first solution; contacting the object with a second solution comprising a polymerizable monomer having at least one free-radical polymerizable group; and irradiating the second solution and the object, wherein the non-polymeric grafting initiator acts as a photoinitiator for a free-radical polymerization reaction.
