Effect of static electricity and thickness of solution blow spun polyamide 6/AgNP nanofibrous membrane on nanoparticle filtration and microbiological activity

•Bactericidal filtration membranes were developed using solution blow spinning.•Four Ag nanoparticles were immobilized on the mats to test the antimicrobial activity.•The effect of static electricity on nanoparticle filtration was investigated.•High filtration efficiency of PM0.3 with low pressure drop was attained.•The membranes are promising for designing facemasks and air filtration systems.
