Summary
Electrospun membranes offer nanoscale fibres, high porosity and interconnected pores, while metal nanoparticles - silver, copper, zinc oxide - kill microbes through their size, shape, ion release and generation of reactive oxygen species. This study combines the two, incorporating copper nanoparticles onto electrospun polyurethane fibres collected on a 50 mm cylindrical collector. The result is a membrane whose antimicrobial action is built into the fibre surface rather than applied as a coating that can wear away.

Linari system with 50 mm cylindrical collector
The membranes were produced on a Linari Engineering S.r.l. system (Pisa, Italy), depositing onto a metallic cylindrical collector of 50 mm diameter covered with aluminium foil - within the 1-100 mm range accepted by our Easy Drum rotary system.
