Abstract
The present invention relates to several novel compositions and methods employing infrared radiation, microwave radiation or high voltage polymerization for modifying the surfaces of materials to impart desired characteristics thereto. More particularly, the present invention relates to a method for modifying the surfaces of objects to increase the lubricity, hydrophilicity, hydrophobicity, or biofunctionality of the surface of the object.
Claims26
A method of modifying a surface of an object, comprising:
- coating the object with a micrograft initiator and a hydrophilic polymer, a hydrophobic polymer, or a biofunctional compound, or a combination of these;
- and,
- exposing the coated object to infrared radiation, microwave radiation or high voltage polymerization, thereby producing a graft to the surface.
A method of modifying a surface of an object, comprising:
- coating the object with (a) a micrograft initiator and (b) a hydrophilic polymer, a hydrophobic polymer, a biofunctional compound, or a combination of these;
- and,
- exposing the coated object to infrared radiation, microwave radiation or high voltage polymerization, thereby producing a graft to the surface, wherein the object is a medical device, surgical instrument or an implant.
A method of modifying a surface of an object, comprising:
- coating the object with (a) a rhicrograft initiator and (b) a hydrophilic polymer, a hydrophobic polymer, a biofunctional compound, or a combination thereof;
- wherein the micrograft initiator comprises (a) a first solution containing polyaniline dissolved in N-methyl pyrrolidinone, (b) a second solution containing copper, perchiorate or p-toluenesulfonic acid, and (c) a peroxide;
- and
- exposing the coated object to infrared radiation, microwave radiation or high voltage polymerization, thereby producing a graft to the surface.
