Most simple preparation of an inkjet printing of silver nanoparticles on fibrous membrane for water purification: Technological and commercial application

In this study, we describe a new approach of antibacterial water-filter generation which utilized inkjet printing to deposit silver nanoparticles onto an electrospun polyurethane fibrous membrane. It was found that the polyurethane fiber was uniformly fabricated and silver nanoparticles were evenly deposited onto the fibrous strands. As an in vitro test, our developed silver-nanoparticle modified polyurethane fibrous membrane showed significant inhibition against four kinds of pathogens that lead to fatal water borne diseases. These results indicate that our approach, which allows for simple, low-cost, mass production of filters, may be useful in the field of water environmental science.
