Abstract
The present invention relates to antimicrobial compositions comprising graphene-silver cation nanocomposites and uses for same as an antimicrobial agent. The antimicrobial agent is particularly useful as a disinfectant or for use as a coating to confer antimicrobial activity to a substrate. The antimicrobial agent can further be used to enhance filtration efficiency in PPE, face masks, and filters in air filtration (HVAC) systems, and other airflow membranes and filters to reduce the transmission of microbial pathogens.
Claims17
An antimicrobial nanocomposite comprising graphene oxide (GO) and silver cations (Ag+) bound to the GO as Ag(1)-complexes, wherein the silver cations (Ag+) are bound to the GO by complex bonds, and wherein the nanocomposite is effective at killing coronavirus.
