In this study, Ag₂O was synthesized on polyethylene terephthalate fabrics by using an ultrasonic technique with Ag ion reduction in an aqueous solution. The effects of pH on the microstructure and antibacterial properties of the fabrics were evaluated. X-ray diffraction confirmed the presence of Ag₂O on the fabrics. The fabrics were characterized by Fourier transform infrared spectroscopy, ultraviolet⁻visible spectroscopy, and wettability testing. Field-emission scanning electron microscopy verified that the change of pH altered the microstructure of the materials. Moreover, the antibacterial activity of the fabrics against was related to the morphology of Ag₂O particles. Thus, the surface structure of Ag₂O particles may be a key factor of the antibacterial activity.
在本研究中，通过在水溶液中采用银离子还原的超声技术，在聚对苯二甲酸乙二酯织物上合成了Ag₂O。评估了pH对织物微观结构和抗菌性能的影响。X射线衍射证实了织物上存在Ag₂O。通过傅里叶变换红外光谱、紫外可见光谱和润湿性测试对织物进行了表征。场发射扫描电子显微镜证实pH的变化改变了材料的微观结构。此外，织物对……的抗菌活性与Ag₂O颗粒的形态有关。因此，Ag₂O颗粒的表面结构可能是抗菌活性的关键因素。
