Abstract:
1. A method for coating an object with a polymer layer comprising: placing the object into a container; filling the container 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 positively charged initiator; irradiating the container having the first solution and the object, resulting in the grafting initiator binding to the object; removing the first solution from the container; filling the container with a second solution comprising a polymerizable monomer having at least one free-radical polymerizable group; and irradiating the container having the second solution and the object, wherein the non-polymeric grafting initiator acts as a photoinitiator for a free-radical polymerization reaction, resulting in the polymerization of the polymerizable monomer and formation of a polymer layer on the object.
