Antibacterial activity of a polymer nanocomposite containing water-soluble poly(ethylene oxide) (PEO), water insoluble poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP), and MoO₃ nanowires or MoO₃ microparticles as antibacterial active substances is reported. The UV-vis absorption method was used for the illumination of dissolving of the MoO₃ particles of different size and morphology in water. Dissolving of MoO₃ nanowires (1 mg ml^-1) decreases pH bellow 3.6 in only 3 min and below 3 in 15 min, while dissolving of the PEO/PVDF-HFP/MoO₃ nanowires coating (5 mg ml^-1) decreases pH bellow 3.6 in 90 min. These coatings completely destroy the Staphylococcus epidermidis ATCC 12228 bacterial strain within 3 h. The proposed applications are antibacterial protective coatings of contact surfaces.

含MoO3纳米线的聚合物共混物，具有对表皮葡萄球菌ATCC 12228的抗菌活性

据报道，含有水溶性聚环氧乙烷（PEO），水不溶性聚偏二氟乙烯-共六氟丙烯（PVDF-HFP）和MoO ₃纳米线或MoO ₃微粒作为抗菌活性物质的聚合物纳米复合物具有抗菌活性。 。紫外可见吸收法用于照明不同大小和形态的MoO ₃颗粒在水中的溶解。溶解MoO ₃纳米线（1 mg ml ^-1）仅在3分钟内降低pH值3.6，在15分钟内降低3以下，而溶解PEO / PVDF-HFP / MoO ₃纳米线涂层（5 mg ml ^-1）降低pH波纹管3.6在90分钟内。这些涂层完全破坏了表皮葡萄球菌ATCC 12228细菌菌株在3小时内。提出的应用是接触表面的抗菌保护涂层。
