  • Patent number: 8691376
    Abstract: UV resistant inorganic coatings which exhibit photochemical activity that destroys toxic biological and chemical agents are disclosed. The inorganic coatings include semiconductor metal oxide nanoparticles that are photo-chemically active dispersed in an inorganic binder. In one embodiment, anatase titanium dioxide nanoparticles are dispersed in a silicon dioxide or silicate binder. Applications may include spacecraft, aircraft, ships, military vehicles, high value equipment and buildings such as subway stations, hospitals, railroad stations and stadiums.
    Type: Grant
    Filed: February 20, 2008
    Date of Patent: April 8, 2014

  • Publication number: 20110220855
    Abstract: A dual action self-cleaning and self-decontaminating coating consisting of a superhydrophobic aspect capable of cleaning the surface by having water droplets moving along the surface remove contaminants and a photochemically active aspect capable of disinfecting the surface by producing hydroxyl radicals in the presence of UV radiation and moisture.
