AB  - Antibacterial properties of engineered materials are important in the transition 
      to a circular economy and societal security, as they are central to many key 
      industrial areas, such as health, food, and water treatment/reclaiming. 
      Nanocoating and electrospinning are two versatile, simple, and low-cost 
      technologies that can be combined into new advanced manufacturing approaches to 
      achieve controlled production of innovative micro- and nano-structured non-woven 
      membranes with antifouling and antibacterial properties. The present study 
      investigates a rational approach to design and manufacture electrospun membranes 
      of polysulfone (PSU) with mechanical properties optimized via combinatorial 
      testing from factorial design of experiments (DOE) and endowed with antimicrobial 
      silver (Ag) nanocoating. Despite the very low amount of Ag deposited as a 
      conformal percolating nanocoating web on the polymer fibers, the antimicrobial 
      resistance assessed against the Gram-negative bacteria E. coli proved to be 
      extremely effective, almost completely inhibiting the microbial proliferation 
      with respect to the reference uncoated PSU membrane. The results are relevant, 
      for example, to improve antifouling behavior in ultrafiltration and reverse 
      osmosis in water treatment.
