Antibacterial Activity and Conductivity Properties of Nanocomposites based on Cellulose Acetate Nanofibers and Copper Nanoparticles

in this work, nanocomposites comprising copper nanoparticle in cellulose acetate (CA)matrices have been prepared. In this manner, Copper nanoparticles prepared by its saltreduced by sodium borohydride at various concentration. Then this nanoparticle solution wasmixed with polymer solution and electrospun by electrospinning device. The abovenanocomposite has been successfully detected by SEM, EDAX, FT-IR and UV-VisSpectroscopy and indicated that not only nanocopper and cellulose nanofiberhave createdgood chemical interaction but also a relatively suitable size and distribution has been yieldedin the fibers. The resulted nanocomposite conductivity by four-probe method showed aremarkable conductivity produced by nanocopper distribution in the tissue of nanocompositesincreasing as concentration rises. In addition, it has been realized that the abovenanocomposites have good antibacterial properties against Staphylococcus aureus (grampositive)and also Escherichia Coli and Klebsiellapneumonia (gram-negative) bacteria.
