  • SELF-DECONTAMINATING, SELF-DEODORIZING TEXTILES AND SURFACES AND METHODS OF MAKING AND USING THE SAME
    Publication number: 20220307194
    Abstract: An article comprising a substrate having a stimuli-responsive hydrogel polymer functionalized to or associated with a surface. The stimuli-responsive hydrogel polymer is at least partially hydrated by an aqueous disinfectant solution comprising a disinfectant. The disinfectant is formed-prior to hydrating the stimuli-responsive hydrogel polymer. At least a portion of the disinfectant is taken up, stored, or released as an aqueous solution or a gaseous vapor upon interaction with a stimulus.

  • Method and composition of humidity-controlled generation of chlorine dioxide in polymers and superabsorbent hydrogels
    Patent number: 11358863
    Abstract: A composition and method for chlorine dioxide production through reaction-diffusion chemistry that facilitates the in situ generation of chlorine dioxide, wherein a dry solid composition of hydroxymethanesulfinic acid monosodium salt dihydrate (abbreviated HMS) and a chlorine dioxide precursor are activated via the addition or absorption of water to produce chlorine dioxide. The dry solid chemical composition comprises dry, safe, transportable reagents that integrate with polymeric materials such as packaging and superabsorbent and stimuli-responsive hydrogel polymers to combine with water to produce chlorine dioxide.
    Type: Grant
