Abstract:
1. A method of preventing the biofouling of a material exposed to a marine environment comprising: dissolving a hydrogel comprising gelatin in water to form a viscous fluid wherein gelatin comprises between about 10% and 40% (w/v) of the hydrogel; applying the viscous fluid to a substrate; applying a cross-linking agent selected from the group consisting of formaldehyde, nordihydroguaiaretic acid, tannic acid, chrome sulfate, and sumac extract to the viscous fluid on the substrate to form an anti-adhesion agent wherein the cross-linking agent is between about 4% and 16% (w/v) of the hydrogel; cooling the substrate coated with the anti-adhesion agent to about 4° C.; and introducing the substrate to the marine environment.
