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.
Claims27
A method of modifying a surface of an object, comprising:
- coating the object with a first solution comprising a micrograft initiator and at least one compound selected from a hydrophilic polymer, a hydrophobic polymer, a biofunctional compound, or a combination thereof;
- exposing the object to infrared radiation, microwave radiation or high voltage polymerization, thereby producing a graft to the surface;
- coating the object with a second solution containing a cellulose compound;
- and
- exposing the object to a heat source to dry and/or cure the object.
A method of modifying a surface of an object, comprising:
- coating the object with a first solution comprising a micrograft initiator, wherein the micrograft initiator comprises a mixture of carboxymethylcellulose, polyaniline in N-methyl pyrrolidinone, p-toluenesulfonic acid in acetonitrile, a peroxide, and water, and at least one compound selected from a hydrophilic polymer, a hydrophobic polymer, a biofunctional compound, or a combination thereof;
- exposing the object to infrared radiation, microwave radiation or high voltage polymerization, thereby producing a graft to the surface;
- coating the object with a second solution containing a cellulose compound;
- and
- exposing the object to a heat source to dry and/or cure the object.
A method of modifying a surface of an object, comprising:
- coating the object with a first solution comprising a micrograft initiator, wherein the micrograft initiator comprises a mixture of polyvinyl alcohol, polyaniline dissolved in N-methyl pyrrolidinone, copper perchlorate in tetrahydrofuran, ethylene glycol, a peroxide, and water, and at least one compound selected from a hydrophilic polymer, a hydrophobic polymer, a biofunctional compound, or a combination thereof;
- exposing the object to infrared radiation, microwave radiation or high voltage polymerization, thereby producing a graft to the surface;
- coating the object with a second solution containing a cellulose compound;
- and
- exposing the object to a heat source to dry and/or cure the object.
