Patent number: 11052385Abstract: The Invention describes integration of photocatalytic materials into composite surfaces in order to achieve antimicrobial properties. Aspects of the invention include types of photocatalytic materials and methods to achieve long lifetimes, high durability and mechanical robustness, for application to medical and sanitary uses, among others. In particular, the invention describes production of photocatalytic islands on a porous support substrate, and various methods to prevent full contact of a matrix material with the photocatalytic islands on the porous support substrate when forming the photocatalytic composite. Reducing the area of contact between the matrix material and the photocatalytic material improves the lifetime of the photocatalytic materials employed in the photocatalytic composite.Type: GrantFiled: December 6, 2018Date of Patent: July 6, 2021Assignee: Sonata Scientific LLCInventors: Peter C.
