Abstract

A method of deterring biofouling of a surface comprising attaching an adduct having formula (I) or noradrenalin to the surface. Formula (I) being defined as compounds that have the formula A-L-R wherein A is i) a C6 or C10 substituted aryl ring, or ii) a C1-C9 substituted or unsubstituted heteroaryl ring: L is a linking group, and R is a primary amino moiety comprising unit.

First claim

What is claimed is:

1. An anti-fouling surface comprising noradrenaline conjugated to a polymer, the polymer including a vinyl resin, a vinyl ester, a vinyl chloride, a polymer of methacrylic acid, or a polymer of 2-hydroxyethyl methacrylate; wherein,
the polymer is grafted to the surface and the polymer attaches the noradrenaline to the surface, the surface being a marine or aquatic surface that contacts fresh water, brackish water, or salt water during use, the anti-fouling surface being resistant to settling and cementation of marine life on the surface.

2. The anti-fouling surface of claim 1 , wherein the anti-fouling surface is resistant to settling and cementation of mollusks, crustaceans, Bryozoa, and/or polychaet.

3. The anti-fouling surface of claim 2 , wherein the anti-fouling surface is resistant to settling and cementation of oysters.

4. The anti-fouling surface of claim 2 , wherein the anti-fouling surface is resistant to settling and cementation of barnacles.

5. The anti-fouling surface of claim 1 , wherein the polymer is a component of a marine paint or varnish.

6. The anti-fouling surface of claim 1 , wherein the surface is at least a portion of the hull of a ship, a propeller, a seismic streamer, a dock, an oil rig, a gas rig, a pipeline, a power plant water intake system, a heat exchanger, a grid, a fish net, or a cage.

7. The anti-fouling surface of claim 1 , wherein the surface comprises metal, wood, concrete or plastic.

8. The anti-fouling surface of claim 1 , wherein the surface is a metal surface.

9. An anti-fouling surface comprising noradrenaline conjugated to a polymer, the polymer comprising —COOH or —OH side groups, the noradrenaline being conjugated to the polymer via reaction between the noradrenaline and the —COOH or —OH side groups; wherein,
the polymer is grafted to the surface and the polymer attaches the noradrenaline to the surface, the surface being a marine or aquatic surface that contacts fresh water, brackish water, or salt water during use, the anti-fouling surface being resistant to settling and cementation of marine life on the surface.

10. The anti-fouling surface of claim 9 , wherein the anti-fouling surface is resistant to settling and cementation of mollusks, crustaceans, Bryozoa, and/or polychaet.

11. The anti-fouling surface of claim 10 , wherein the anti-fouling surface is resistant to settling and cementation of oysters.

12. The anti-fouling surface of claim 10 , wherein the anti-fouling surface is resistant to settling and cementation of barnacles.

13. The anti-fouling surface of claim 9 , wherein the polymer is a component of a marine paint or varnish.

14. The anti-fouling surface of claim 9 , wherein the surface is at least a portion of the hull of a ship, a propeller, a seismic streamer, a dock, an oil rig, a gas rig, a pipeline, a power plant water intake system, a heat exchanger, a grid, a fish net, or a cage.

15. The anti-fouling surface of claim 9 , wherein the surface comprises metal, wood, concrete or plastic.

16. The anti-fouling surface of claim 9 , wherein the surface is a metal surface.

17. The anti-fouling surface of claim 9 , wherein the surface further comprises a phenolic resin, a silicone polymer, a chlorinated rubber, a coal tar, an epoxy resin, a polyamide resin, a vinyl resin, an elastomer, an acrylate polymer, a fluoropolymer, a polyester, a polyurethane, or a latex.

18. The anti-fouling surface of claim 9 , wherein the polymer is a polymer of methacrylic acid, or a polymer of 2-hydroxyethyl methacrylate.
