Abstract

The present application relates to an antimicrobial coated substrate with one or more surfaces and a TiO2 coating on at least one of the surfaces of the substrate, where the coating has a rhombohedral microstructure. Also disclosed is a process for preparing an antimicrobial coated substrate with one or more surfaces and methods of killing microbes.

Claims

An antimicrobial coated substrate comprising: a substrate with one or more surfaces and a TiO2 coating on at least one of the surfaces of the substrate, wherein the coating has a rhombohedral microstructure.
The antimicrobial coated substrate of claim 1, wherein the substrate is metal containing.
The antimicrobial coated substrate of claim 2, wherein the substrate is stainless steel.
The antimicrobial coated substrate of claim 1, wherein the substrate is plastic or glass.
The antimicrobial coated substrate of claim 1, wherein the TiO2 coating has an areal porosity of 0 to 95.
The antimicrobial coated substrate of claim 1, wherein the TiO2 coating has a thickness of 595 to 2044 nm.
The antimicrobial coated substrate of claim 1, wherein the TiO2 coating has a pencil hardness of 6B to HB.
The antimicrobial coated substrate of 1, wherein the TiO2 coating has an elastic modulus of 37.1 to 247 GPa.
The antimicrobial coated substrate of claim 1, wherein the TiO2 coating comprises an anatase or rutile crystal structure.
The antimicrobial coated substrate of claim 1, wherein the TiO2 coating comprises a brookite crystal structure.
The antimicrobial coated substrate of claim 9 wherein the TiO2 coating comprises 90 to 100% anatase and 0 to 10% rutile crystal structure.
The antimicrobial coated substrate of claim 1, said substrate is made from a material suitable for contact with foods.
A process for preparing an antimicrobial coated substrate, said process comprising: providing a substrate with one or more surfaces; applying a TiO2-containing sol-gel material to at least one surface of the substrate to produce a TiO2-containing sol-gel coated substrate; and sintering the TiO2-containing sol-gel coated substrate to produce an anti-microbial TiO2 coated substrate. 14.-33. (canceled)
The anti-microbial substrate prepared by the process of claim 13.
A method of killing microbes, said method comprising: providing a TiO2 film with a rhombohedral microstructure and contacting the TiO2 film with microbes under conditions effective to kill the microbes. 36.-49. (canceled)
A method of killing microbes, said method comprising: providing a surface containing, or capable of containing, microbes and placing, in contact with the surface, a TiO2 with a rhombohedral microstructure to kill the microbes. 51.-64. (canceled)
