Herein, poly(propylene) (PP) was hydrophilized with oxidating agents and solvents, followed by dip-coating with silver nanoparticles anchored GO sheets (Ag@GO) prepared by the in-situ method as reported in our previous study to obtain silver@graphene oxide-coated poly(propylene) (Ag@GO/PP). The impact of the modifying agents, dipping times, and coating concentrations on the antibacterial activities were studied accordingly via the inhibition zone method. The fabrics were re-hydrophobized with the reduction of Ag@GO and the functionalization with stearic acid (SA) to form silver@reduced graphene oxide-coated poly(propylene) (Ag@rGO/PP) and silver@graphene oxide/SA-coated poly(propylene) (Ag@rGO-SA/PP), respectively. Characterization of pretreated and modified PP samples was carried out by various modern analysis methods. Simultaneously, the cytotoxicity of the active layers, the release of Ag⁺ ions, and durability after washing were also investigated. The obtained results representing PP fabrics pretreated with HNO₃/isopropanol and dipped in Ag@GO concentration of 2 g/L four times prove a sufficient approach for improving hydrophilization and bio-compatibility for the PP samples. The fabrics greatly show an impressive interaction with precursors, mostly high antibacterial activity even after four washing cycles via appropriate releasing of Ag⁺ to ensure the safety in usage. They further suggest that the prepared fabrics could be utilized for actual application as a face mask.

用于抗菌应用的氧化石墨烯基银纳米粒子对聚丙烯织物的表面改性

在这里，聚（丙烯）（PP）用氧化剂和溶剂亲水化，然后用我们之前研究中报道的原位方法制备的银纳米颗粒锚定的GO片材（Ag@GO）浸涂以获得银@氧化石墨烯涂层的聚（丙烯）（Ag@GO/PP）。通过抑菌圈法研究了改性剂、浸渍时间和包衣浓度对抗菌活性的影响。织物通过还原 Ag@GO 和用硬脂酸 (SA) 功能化重新疏水化，形成银@还原氧化石墨烯包覆的聚丙烯 (Ag@rGO/PP) 和银@氧化石墨烯/SA-涂层聚（丙烯）（Ag@rGO-SA/PP），分别。通过各种现代分析方法对预处理和改性 PP 样品进行了表征。同时，⁺离子和洗涤后的耐久性也进行了研究。所获得的 PP 织物用 HNO ₃ /异丙醇预处理并浸入浓度为 2 g/L 的 Ag@GO 中四次的结果证明是提高 PP 样品的亲水性和生物相容性的充分方法。该织物与前体的相互作用非常显着，即使经过四次洗涤循环后，通过适当释放Ag ⁺以确保使用安全，大多数情况下仍具有很高的抗菌活性。他们进一步建议，制备的织物可用于实际应用作为面罩。
