Abstract
The present invention provides a coating comprising cinnamaldehyde, a cinnamaldehyde derivative, an essential oil, or an essential oil-derived compound; and a polyphenol, polyethyleneimine or poly(4-vinylaniline). The invention also provides a coating comprising cinnamaldehyde, a cinnamaldehyde derivative, an essential oil, or an essential oil-derived compound; a metal, metal-salt or metal-compound; and a polyphenol or a polyphenol-containing substance or solution. Substrates including the coatings applied thereto, and methods of preparing the coatings are also provided.
Claims20

- cinnamaldehyde, a cinnamaldehyde derivative, an essential oil, or an essential oil-derived compound;
- and
- a polyphenol, polyethyleneimine or poly(4-vinylaniline).
(canceled)
-13. (canceled)
A method of preparing a coating, said method including the steps of:
- providing an amount of cinnamaldehyde, a cinnamaldehyde derivative, an essential oil, or an essential oil-derived compound;
- mixing said cinnamaldehyde, cinnamaldehyde derivative, essential oil, or essential oil-derived compound with an amount of a polyphenol, polyethyleneimine or poly(4-vinylaniline);
- placing a substrate into the combined mixture for a predetermined period of time;
- removing the substrate from the mixture;
- washing, and subsequently drying the substrate to provide the same with the coating thereon.
A method of preparing a coating, said method including the steps of:
- providing a solution of cinnamaldehyde, a cinnamaldehyde derivative, an essential oil, or an essential oil-derived compound;
- providing a substrate on to which the coating is to be applied;
- functionalising the surface of the substrate via the deposition of a polymer thereon;
- immersing the polymer-coated substrate into the solution of cinnamaldehyde, cinnamaldehyde derivative, essential oil, or essential oil-derived compound for a predetermined period of time;
- removing the substrate from the solution;
- washing, and subsequently drying the substrate to provide the same with the coating thereon.
17-18. (canceled)
A coating, said coating comprising:
- cinnamaldehyde, a cinnamaldehyde derivative, an essential oil, or an essential oil-derived compound;
- a metal, metal-salt or metal-compound;
- and
- a polyphenol or a polyphenol-containing substance or solution.
