Abstract
Disclosed are methods and compounds useful for forming coatings applied to porous and non-porous surfaces to make the surface antimicrobial and to protect against contaminants. The coatings are formed from phenolic compounds present in a solvent either alone or in combination with other compounds, such as metallic salts.
Claims25
A method of forming a coating on a substrate comprising the steps of:
- (a) providing a solution consisting of a phenolic compound and a low-valent metallic salt both placed in a solvent, wherein
- (i) the phenolic compound comprises phenolic molecules and the low-valent metallic salt comprises metal ions that chelate to link the phenolic molecules,
- (ii) the phenolic compound is present in the solution at a concentration between 0.001 mg/mL and 50 mg/mL, and
- (iii) less than 50% of the phenolic molecules are covalently polymerized;
- and
- (b) contacting at least part of a substrate with the solution, wherein the phenolic molecules create a coating disposed on the substrate.

A method of forming a coating on a substrate comprising the steps of:
- (a) contacting a substrate with a first solution, wherein the first solution consisting of phenolic compound comprising phenolic molecules in a first solvent;
- and
- (b) contacting the substrate with a second solution before the first solution dries on the substrate, wherein
- (i) the second solution comprises a low-valent metallic salt dissolved in a second solvent,
- (ii) the low-valent metallic salt comprises metal ions that chelate to link the phenolic molecules, and less than 50% of the phenolic molecules are covalently polymerized during the coating process, and
- (iii) the phenolic molecules create a coating disposed on the substrate.
