Composition and method to form a self decontaminating surface

摘要

A method to prepare a self-decontaminating surface, where that method includes dissolving tartaric acid in water, adding titanium (IV) isopropoxide to the tartaric acid solution to form a coating composition in water, and casting that coating composition onto a surface to form a coating having anti-microbial function.

主权项

1. A coating disposed on a surface, formed by the method consisting of:
dissolving tartaric acid in water; forming an opaque gel by adding titanium (IV) isopropoxide to said tartaric acid solution to form an 18 weight percent loading of tartaric acid and titanium (IV) isopropoxide in water; diluting said gel with water to form a 10 weight percent loading of tartaric acid and titanium (IV) isopropoxide in water; casting said 10 weight percent aqueous gel onto a surface to form a coating; inoculating said surface with MRSA bacteria, wherein: said inoculated surface comprises an initial MRSA concentration; said inoculated surface shows greater than a log 5.6 reduction in MRSA concentration after 2 hours.
