AB  - Membrane fouling problem impedes widespread application of polyvinylidene 
      fluoride (PVDF) membrane for water treatment. This study proposed a novel 
      strategy to endow hydrophobic PVDF ultrafiltration (UF) membrane with good 
      antifouling and antibacterial activity. The novel strategy includes 3 steps: 
      polydopamine (PDA) modification, Ag catalytic activation and electroless Cu 
      plating. Via this strategy, copper nanoparticles (CuNPs) were in situ immobilized 
      on PVDF membrane. The adhesive PDA layer not only facilitated to firm attachment 
      of CuNPs, but also increased surface hydrophilicity. Scanning electron microscope 
      (SEM) and X-ray photoelectron spectroscopy (XPS) analyses confirmed successful 
      immobilization of CuNPs, which improved surface hydrophilicity and absolution 
      value of negative zeta potential as compared with the pristine PVDF membrane. 
      Meanwhile, the modified Cu/PDA/PVDF membrane had relatively high conductivity, 
      significantly improving antifouling performance when 0.30 V cm(-1) of external 
      electrical field was applied. Antibacterial tests revealed that the modified 
      membrane possessed significantly enhanced antibacterial activity against live E. 
      coli. The novel modification strategy in this study gave important implications 
      for membrane fabrication, and the modified membrane possessed attractive 
      potential in water treatment.
