Photogenerated fluphenazine radical cations for antiviral functionalization of polypropylene masks

Polymer International, EarlyView.
Fluphenazine impregnated into nonwoven polypropylene masks is photoexcited to a radical cation, which inactivates viruses on the polymer surface without causing damage to the masks. Abstract The incorporation of photoactive molecules into polymeric substrates offers a compelling route to introduce advanced functionality while preserving the host ...
