  • Patent number: 10561763
    Abstract: Certain embodiments include materials that carry oxygen and emit molecular oxygen upon heating. The approach reported here uses thermal decomposition of organic endoperoxide compounds to produce singlet oxygen. In certain aspects the oxygen carrier comprises an organic compound either alone or contained in a polymeric carrier or other carrier material that is used to form a coating, layer, or bulk substance that can be a solid, a gel or a fluid. The oxygen-carrier is most conveniently prepared by oxidation of a precursor compound, the structure of which determines its thermal stability and thus how rapidly oxygen is released at any given temperature.
    Type: Grant
    Filed: August 16, 2017
    Date of Patent: February 18, 2020
    Assignee: THE BOARD OF REGENTS OF THE UNIVERSITY OF TEXAS SYSTEM
