  • Self-decontaminating inorganic coatings containing semiconductor metal oxide nanoparticles
    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
    Assignee: Northrop Grumman Systems Corporation
    Inventors: John Douglas Weir, Ronald Gary Pirich, Donald DiMarzio, Dennis J. Leyble, Steven Chu
