Abstract:
1. A process for growing a polyethylene glycol alkyl acrylate polymer film gradient on a substrate having a moiety accepting surface comprising the step of: (a) contacting at least one initiator molecule with the moiety accepting surface of a substrate to form an initiator coated substrate, said initiator molecule comprising at least one of (b) adding a first and second layer of liquid to a coating container, said first and second layer of liquid being added as separate discreet additions to said container; (c) inserting the initiator-coated substrate of step (a) into the coating container; and (d) allowing a sufficient amount of time for diffusion of the polyethylene glycol alkyl acrylate monomer to occur between said first and second liquid layers, wherein a polyethylene glycol alkyl acrylate gradient is grown on the surface of the initiator-coated substrate.
