In the current work, the polypropylene composites filled with a M-T-ZnOw@Ag filler with antibacterial and antistatic properties was firstly synthesized. The composites and the fabricated nanocomposites were characterized using SEM, TEM, XRD, FTIR and XPS techniques. With the addition of M-T-ZnOw@Ag, the antibacterial and antistatic properties of composite materials are greatly improved by the synergistic effect of AgNPs and T-ZnOw. When the filler content is 10 wt%, the antibacterial activity of the composite material against Gram negative (Escherichia coli) and Gram positive (Staphylococcus aureus) bacterial were 100%. And the surface resistivity was reduced to 5.5 × 10¹⁰ Ω, fell by nearly 7 orders of magnitude compare with the neat PP. Furthermore, the composites showed better mechanical properties. The maximum impact strength of the composites is 56.3% higher than the neat PP. We believe the composite material with antibacterial and antistatic properties could greatly expand the application range of polypropylene materials.

在目前的工作中，首次合成了填充具有抗菌和抗静电性能的 MT-ZnOw@Ag 填料的聚丙烯复合材料。使用 SEM、TEM、XRD、FTIR 和 XPS 技术对复合材料和制备的纳米复合材料进行表征。随着MT-ZnOw@Ag的加入，AgNPs和T-ZnOw的协同作用大大提高了复合材料的抗菌和抗静电性能。当填料含量为10wt%时，复合材料对革兰氏阴性（大肠杆菌）和革兰氏阳性（金黄色葡萄球菌）细菌的抗菌活性为100%。并且表面电阻率降低到 5.5 × 10 ¹⁰Ω，与纯 PP 相比下降了近 7 个数量级。此外，复合材料表现出更好的机械性能。复合材料的最大冲击强度比纯 PP 高 56.3%。我们相信具有抗菌和抗静电性能的复合材料将大大扩展聚丙烯材料的应用范围。
