  • Patent number: 10828400
    Abstract: A substrate subject to degradation at temperatures above 100° C. is coated with a nanostructured ceramic coating having a thickness in excess of 100 nm, formed on a surface of the substrate, wherein a process temperature for deposition of the nanostructured coating does not exceed 90° C. The coating may be photocatalytic, photovoltaic, or piezoelectric. The coating, when moistened and exposed to ultraviolet light or sunlight, advantageously generates free radicals, which may be biocidal, deodorizing, or assist in degradation of surface deposits on the substrate after use. The substrate may be biological or organic, and may have a metallic or conductive intermediate layer.
