Medical protective masks with both high antibacterial activity and filtration efficiency have gained wide interest due to sporadic respiratory disease outbreaks. Previous studies focused on improving a single function (antibacterial or filtration) of the mask performance. Herein, we developed silver nanoparticles-decorated PVDF membranes (AgNPs/PVDF) efficiency. Our results show that AgNPs/PVDF 99.98% 99.86% against E. coliand S. aureus, respectively. The bacterial is higher than 95%. PM0.26 can be maintained above 95% after continuous for 144 min. Adding AgNPs also promotes distinct hierarchical structure formation, which could improveme This study provides new methodology fabricate doped metal nanoparticles promising applications in personal equipment development.
