Abstract
An open-cell foam structure that is impregnated with a disinfectant and used to remove pathogens from air, water, and surfaces, and kill the pathogens.
Claims12
A method of killing pathogens, comprising:
- providing a structure that comprises an open-cell polymer foam;
- incorporating biochar into the open-cell polymer foam or coupling biochar to the structure;
- impregnating the open-cell polymer foam of the structure with a hydronium-based disinfectant that is configured to kill pathogens;
- and
- exposing the disinfectant-impregnated open-cell polymer foam of the structure to the pathogens such that the disinfectant-impregnated open-cell polymer foam of the structure contacts and kills the pathogens.

A method of remediating pathogens, comprising:
- providing a structure that comprises an open-cell polymer foam;
- incorporating biochar into the open-cell polymer foam or coupling biochar to the structure;
- exposing the structure to at least one of air and water such that the open-cell polymer foam of the structure contacts pathogens;
- and
- either before or after the exposing step, applying to the open-cell polymer foam of the structure a hydronium-based disinfectant that is configured to kill pathogens that come into contact with the open-cell polymer foam of the structure.
