Abstract
The present invention relates to novel chemical solutions suitable for forming polymer brushes on a surface of a solid part. The present invention further relates to methods of forming polymer brushes on the surface of a solid part using the novel chemical solutions as well as solid parts having polymer brushes coated onto the surface and uses of such solid parts.
Claims36
A reaction composition for forming polymer brushes on a surface of a solid part comprising:
- at least one polymerisation composition, and at least one activation agent;
- one or more monomers provided as one or more of (i) a part of the polymerisation composition, (ii) a part of the activation agent, or (iii) a discrete composition;
- wherein the at least one polymerisation composition comprises one or more dormant transition metal catalysts derived from Cu and Fe and selected from Cu2O, CuO, Cu, CuSO4*5H2O, FeO, Fe2O3, and Fe3O4, in combination with a ligand capable of coordinating with the transition metal;
- wherein the at least one activation agent comprises one or more oxygen scavengers;
- wherein the at least one polymerisation composition and the at least one activation agent are provided as discrete compositions;
- and
- wherein the reaction composition is in contact with the solid part comprising polymerisation initiators immobilised on the surface.

A method of forming polymer brushes on a solid part comprising the steps of:
- providing the solid part having polymerisation initiators immobilised on a surface of said solid part,
- mixing a polymerisation composition and an activation agent, further comprising one or more monomers provided as one or more of (i) part of the polymerisation composition, (ii) part of the activation agent, or (iii) a discrete composition, to form a reaction composition of,
- wherein the polymerisation composition comprises one or more dormant transition metal catalysts derived from Cu and Fe and selected from Cu2O, CuO, Cu, CuSO4*5H2O, FeO, Fe2O3, and Fe3O4, in combination with a ligand capable of coordinating with the transition metal,
- wherein the activation agent comprises one or more oxygen scavengers, and the method further comprises
- bringing the reaction composition and the solid part into contact either mixed prior to contact with the solid part, or mixed upon contact with the solid part, thereby initiating surface polymerisation on the solid part, whereby polymer brushes are formed via the polymerisation initiators on the surface of the solid part.
