Abstract

Cutin-based devices, coatings and methods of producing such devices and coatings are presented herein. Cutin-like materials (CLMs) are presented which mimic and adapt coatings found in nature for the next generation of functional coatings. Cutin has several advantages including excellent UV resistance, natural resistance to bacteria and viruses, noncorrosive, and stability under abrupt changes in temperature and environment. CLMs can be engineered at the nanoscale and readily impregnated with metals and metal oxides materials.

First claim

What is claimed is:

1. A method of manufacturing cutin-like materials (CLM) for use in two-dimensional coatings and three-dimensional structures comprising:
providing CLM precursors in a solution;
adding substituted w-hydroxyl fatty acids to the solution;
adding glycerol or ferulate to the solution; and
adding an acid or base to the solution to catalyze a reaction between oxygen donor groups, the glycerol and the CLM precursors;
wherein the reaction promotes formation of CLM.

2. The method of claim 1 , wherein the CLM precursors are naturally derived.

3. The method of claim 2 , wherein the CLM precursors are derived from cutin found in cacti species selected from the group consisting of Opuntia ficus - indica, Agave Americana, Cereus peruvianus , and Rhipsalis species.

4. The method of claim 1 , wherein the CLM precursors are synthetically derived.

5. The method of claim 1 , wherein the CLM precursors are C 12 -C 20 aliphatic fatty acids.

6. The method of claim 5 , wherein the aliphatic fatty acids are linked together via esterification to result in areas of CLM.

7. The method of claim 1 , further comprising incorporating fatty acid iron or copper salts into the solution.

8. The method of claim 1 , further comprising incorporating metallic and dielectric materials into the solution to enhance surface reactivity and reflecting properties of the CLM.

9. The method of claim 8 , wherein the metallic materials are selected from the group consisting of iron (Fe) and gold (Au).

10. The method of claim 8 , wherein the dielectric materials are selected from the group consisting of silicon dioxide (SiO 2 ) and silicon nitride (Si 3 N 4 ).
