Formable aquatic coverings for preventing biofouling
The instant invention describes an anti-biofouling structure for placement onto structures or surfaces that are exposed to aquatic environments. Embedded within the anti-biofouling structure are agents that can diffuse out of the structure and prevent the formation and/or accumulation of plant and animal species build-up that creates biofouling. The instant invention also describes a system for preventing biofouling of an object stored in an aquatic environment which includes the anti-biofouling structure, and a protective cover element constructed and arranged to fit various structures, such as boat propellers.
1. An anti-biofouling structure for securement around or onto an object exposed to an aquatic environment, the structure comprising:
a flexible covering material formed from a plurality of interwoven fibers that form a lattice-like configuration that allows passage of at least some of said aquatic environment therethrough;
wherein said covering material comprises at least one anti-fouling agent coated thereon or embedded therein and configured to interact with the at least some of said aquatic environment;
wherein said covering material is securable about at least a portion of said object to cover the at least a portion of the object to reduce formation of biofouling organisms along the at least a portion of said object that is covered, and
wherein the anti-biofouling structure is formable so as to be capable of being expanded three-dimensionally, radially, longitudinally, or combinations thereof for positioning at least partially around the object to mirror a contour of the portion of the object being covered.
2. The anti-biofouling structure of claim 1 , wherein the anti-fouling agent is microencapsulated.
3. The anti-biofouling structure according to claim 1 , wherein the anti-biofouling structure is in the form of a rolled up sheet.
4. The anti-biofouling structure of claim 3 , wherein the anti-fouling agent is microencapsulated.
5. The anti-biofouling structure of claim 3 , wherein the anti-fouling agent is applied to the covering material via a spray-on application.
6. The anti-biofouling structure of claim 3 , wherein the covering material further comprises one or more fastening elements for securing the covering material around or onto the object, wherein the one or more fastening elements comprises at least one of loop and hook type fasteners, snaps, buttons, glue strips, or zippers.
7. The anti-biofouling structure of claim 6 , wherein the one or more fastening elements are configured to secure to the covering material such that the covering material is configured to secure to itself.
8. The anti-biofouling structure of claim 1 , wherein the anti-fouling agent is applied to the covering material via a spray-on application.
9. The anti-biofouling structure of claim 1 further comprising one or more fastening elements for securing the covering material around or onto the object, wherein the one or more fastening elements comprises at least one of loop and hook type fasteners, snaps, buttons, glue strips, or zippers.
10. The anti-biofouling structure of claim 9 , wherein the one or more fastening elements are configured to secure to the covering material such that the covering material is configured to secure to itself.
11. A system for reducing biofouling of an object in an aquatic environment, the system comprising:
the object; and
the anti-biofouling structure according to claim 1 secured to the object.
12. The system of claim 11 , wherein the anti-fouling agent is microencapsulated.
13. The system of claim 11 , wherein the anti-fouling agent is applied to the covering material via a spray-on application.
14. The system of claim 11 , wherein the anti-biofouling structure further comprises one or more fastening elements for securing the covering material around or onto the object, wherein the one or more fastening elements comprises at least one of loop and hook type fasteners, snaps, buttons, glue strips, or zippers.
15. The system of claim 14 , wherein the one or more fastening elements are configured to secure to the covering material such that the covering material is configured to secure to itself.
