Summary:A novel hybrid material, Cu-PAA/MWCNTs （copper nanoparticles deposited multiwalled carbon nano- tubes with poly （acrylic acid） as dispersant, was prepared and expected to obtain a more effective and well-dispersed disinfection material for water treatment. X-ray energy dispersive spectroscopy （EDS）, transmission electron microscopy （TEM）, the X-ray fluorescence （XRF）, X-ray photoelectron spectra （XPS）, Fourier transform infrared spectra （FT-IR）, Raman spectroscopy, and thermal gravi- metric analyzer （TGA） were used to characterize the Cu- PAA/MWCNTs. Escherichia coli （E. coil） was employed as the target bacteria. The cell viability determination and fluorescence imaging results demonstrated that Cu-PAA/ MWCNTs possessed strong antimicrobial ability on E. coil. The deposited Cu was suggested to play an important role in the antimicrobial action of Cu-PAA/MWCNTs.
