Silver ion exchange fillers incoporated with mixed matrix membrane for antibacterial application

The objective of this work is to investigate silver ion exchanged fillers in the mixed matrix membrane for antibacterial application. Flat sheet Polyethersulfone (PES) mixed matrix membrane (MMM) was fabricated and characterized. MMM was fabricated using a dry/wet phase inversion technique. The work...
