Facile fabrication and characterization of poly(tetrafluoroethylene)@polypyrrole/nano-silver composite membranes with conducting and antibacterial property

► We prepared two kinds of poly(tetrafluoroethylene)@ polypyrrole/nano-silver composite membranes. ► Both of them have suitable for gas/solid isolation with bi-functionality of conducting and antibacterial property. ► They can annihilate the bacteria filled in the air at the same time of air filtration due to the existence of nano-silver.
