In this study, CuO-ZnO composite was synthesized via the sol-gel method using oxalic acid to form the medium complex and its applications in antibacterial have been conducted with B. cereus, E. coli, S. aureus, Salmonella, and P. aeruginosa. Then, nanopowder of CuO-ZnO was coated on shoe insoles and their antibacterial effect with S. aureus was tested. The nanocomposite products were characterized by XRD, XPS, SEM, TEM, and UV-Vis. The results showed that the CuO-ZnO composite has the average particle size in a range of 20-50 nm, the point of zero charge of 7.8, and the bandgap of 1.7 eV. XPS result shows the composite structure with Cu2+ in the product. The minimum inhibitory concentration (MIC) of CuO-ZnO nanocomposite was 0.313 mg·mL-1 for S. aureus and Samonella, 0.625 mg·mL-1 for E. coli, and 5 mg·mL-1 for B. cereus and P. aeruginosa. The shoe insoles coated with 0.35 wt.% of CuO-ZnO nanocomposite also had high antibacterial activity against S. aureus, and this antibacterial nanocomposite was implanted durably on the surface of the shoe insoles.

溶胶-凝胶法合成抗菌鞋内底包覆的CuO-ZnO纳米复合材料
在这项研究中,使用草酸通过溶胶-凝胶法合成了CuO-ZnO复合材料,形成了介质配合物,并已在蜡状芽孢杆菌,大肠杆菌,金黄色葡萄球菌,沙门氏菌和P.进行了抗菌应用。铜绿。然后,将纳米粉末CuO-ZnO涂覆在鞋垫上,并测试其对金黄色葡萄球菌的抗菌作用。通过XRD,XPS,SEM,TEM和UV-Vis对纳米复合产品进行了表征。结果表明,CuO-ZnO复合材料的平均粒径在20-50 nm范围内,零电荷点为7.8,带隙为1.7 eV。XPS结果显示了Cu 2+的复合结构在产品中。CuO-ZnO纳米复合材料的最低抑菌浓度(MIC)对金黄色葡萄球菌和沙门氏菌为0.313 mg·mL -1,对大肠杆菌为0.625 mg·mL -1,对蜡状芽孢杆菌和P为5 mg·mL -1 。绿脓杆菌。涂覆有0.35重量%的CuO-ZnO纳米复合材料的鞋垫还具有对金黄色葡萄球菌的高抗菌活性,并且该抗菌纳米复合物被持久地植入到鞋垫的表面上。
