Abstract The TiO2 nanoparticles, PVA/TiO2 and PEG/TiO2 composites were syntheses by using the sol-gel method. For the characterization of synthesized TiO2, PVA/TiO2, and PEG/TiO2 composites, SEM-EDS, XRD, FTIR, and TGA measurements were used. Hardness measurements were done using Vickers hardness tester. The photocatalytic and antibacterial activities of TiO2 nanoparticles, PVA/TiO2 and PEG/TiO2 were determined using by Acid Black I dye and E. coli bacteria, respectively. As a result of photocatalytic and antibacterial experiments, PEG/TiO2 composite showed better activity compared to other samples. The dye decomposition of the PEG/TiO2 composite is 62.82% while the bacteria removal is 26.2%.

煅烧纳米二氧化钛/聚合物复合材料的热、光催化和抗菌性能

摘要 采用溶胶-凝胶法合成了TiO2纳米颗粒、PVA/TiO2和PEG/TiO2复合材料。为了表征合成的 TiO2、PVA/TiO2 和 PEG/TiO2 复合材料，使用了 SEM-EDS、XRD、FTIR 和 TGA 测量。使用维氏硬度计进行硬度测量。分别使用酸性黑 I 染料和大肠杆菌来测定 TiO2 纳米颗粒、PVA/TiO2 和 PEG/TiO2 的光催化和抗菌活性。作为光催化和抗菌实验的结果，与其他样品相比，PEG/TiO2 复合材料显示出更好的活性。PEG/TiO2复合材料的染料分解率为62.82%，细菌去除率为26.2%。
