The fabrication of as-spun copper (II) sulfate polyacrylonitrile (PAN) composite nanofibers, copper hydroxide nanowires (Cu(OH)₂ NWs), copper oxide nanowires (CuO NWs), and copper nanoparticles (Cu NPs) incorporated in/on PAN nanofibers were presented. SEM, TEM, FTIR, XRD, and XPS confirmed the success of the syntheses. The surface wettability was also investigated for all samples. All copper composite nanofibers exhibited considerable antibacterial properties against Escherichia coli (E. coli) and Bacillus subtilis (B. subtilis) and were compared to each other to investigate the mechanistic actions of different copper species. The results of the antibacterial assays suggested that the antibacterial effects of copper-containing samples were dependent on the release of soluble copper, including copper ions (Cu²⁺), the shape of the nano copper, and the copper content of the composite nanofibers.

PAN中掺入的初生硫酸铜（II）聚丙烯腈（PAN）复合纳米纤维，氢氧化铜纳米线（Cu（OH）₂ NWs），氧化铜纳米线（CuO NWs）和铜纳米颗粒（Cu NPs）的制造提出了纳米纤维。SEM，TEM，FTIR，XRD和XPS证实了合成的成功。还研究了所有样品的表面润湿性。所有铜复合纳米纤维对大肠杆菌（E. coli）和枯草芽孢杆菌（B. subtilis）均具有显着的抗菌性能。）并相互比较以研究不同铜物种的机械作用。抗菌测定的结果表明，含铜样品的抗菌效果取决于可溶性铜的释放，包括铜离子（Cu ²⁺），纳米铜的形状和复合纳米纤维的铜含量。
