Abstract: In this paper, ZnO/Ag composite antibacterial was firstly modified by using titanate coupling agent TC-27. Modified and unmodified ZnO/Ag antibacterial were then used as functional additives to add into the medical PVC to prepare antibacterial PVC. The effects of modification and the adding amount of antibacterial on the mechanical properties and antibacterial performances of the antibacterial PVC were investigated. Results indicated that the activation rate and lipophilicity of the modified composite antibacterial were enhanced, which induced tensile strength and elongation at break of antibacterial PVC superior to those of common PVC. The surface modification had little influence on antibacterial performances of the antibacterial PVC. When modified and unmodified ZnO/Ag composite were both added to 3wt%, the inhibition rates of the antibacterial PVC on E. coli and Staphylococcus aureus were both above 90%.
