Anti-microbial coating and method to form same
An anti-microbial coating formulation consisting essentially of triethanolamine and a silane.
1. An antimicrobial coating formulation comprising:
89.48 vol. % methanol;
5.26 vol. % triethanolamine; and
5.26 vol. % of a silane having a structure:
wherein the volume percentages are based on the total volume of the formulation.
2. The antimicrobial coating formulation of claim 1 , wherein:
said antimicrobial coating formulation, when dried on a surface, exhibits a 6.5 log reduction in murine norovirus 4 hours after initial inoculation of murine norovirus on said surface.
3. The antimicrobial coating formulation of claim 2 , wherein said surface is formed from stainless steel.
4. An antimicrobial coating formulation consisting essentially of:
a silane having a structure:
a mixture of Peroxotitanium acid and Peroxo-modified anatase sol;
and triethanolamine.
5. The antimicrobial coating formulation of claim 4 , wherein:
said antimicrobial coating formulation, when dried on a surface, exhibits a ≥2.91 log reduction in murine norovirus 4 hours after initial inoculation of murine norovirus on said surface.
6. The antimicrobial coating formulation of claim 5 , wherein said surface is formed from stainless steel.
7. The antimicrobial coating formulation of claim 2 , wherein drying on a surface comprises allowing at least 90 wt. % of the methanol liquid carrier to evaporate to provide a deposition consisting essentially of said silane and triethanolamine.
8. A method to prepare an antimicrobial surface, comprising:
disposing on a surface an antimicrobial coating formulation comprising 5.26 vol. % triethanolamine, 89.48 vol % methanol, and 5.26 vol. % of a silane having a structure:
wherein the volume percentages are based on the total volume of the formulation;
allowing said methanol to evaporate to form a coating consisting essentially of said silane;
disposing a mixture of Peroxotitanium acid and Peroxo-modified anatase sol in a water carrier onto said surface; and
allowing said water carrier to evaporate to form a Titanyl-Oxide coating consisting essentially of said mixture of Peroxotitanium acid and Peroxo-modified anatase sol.
9. The method of claim 8 , wherein:
said silane coating is first formed on said surface;
said Titanyl-Oxide coating is formed over said silane coating.
10. The method of claim 8 , wherein:
said Titanyl-Oxide is first formed on said surface;
said silane coating is formed over said Titanyl-Oxide coating.
11. A method to prepare an antimicrobial surface, comprising:
disposing an antimicrobial coating formulation consisting essentially of a silane, triethanolamine, and a mixture of Peroxotitanium acid and Peroxo-modified anatase sol, in a liquid carrier on a surface, wherein said silane has the structure:
and
allowing said liquid carrier to evaporate.
