摘要
采用水热法制备Ag掺杂量不同的Ag/TiO2纳米复合材料,通过原位聚合法制备PANI/Ag-TiO2纳米纤维复合材料,利用XRD、SEM、FT-IR等检测技术对复合材料的结构进行了表征。研究了光源、Ag掺杂量、不同实验菌种等因素对PANI/Ag-TiO2纳米纤维复合材料抗菌性能的影响。结果表明:在无光照射情况下,PANI/Ag-TiO2纳米纤维复合材料具有良好的抗菌性能,在长波紫外光照射情况下,抗菌性能进一步增强。在浓度1mg/mL时,在无需光照的情况下对4种实验菌种杀菌率均达到99.99%。
The nanocomposites of TiO2 doped with different Ag contents were prepared by hydrothermal process, and PANI/Ag-TiO2 fibrous nanocomposites were synthesized via in-situ polymerization. The structures of products were characterized by the detection techniques including XRD, SEM and FT-IR. The effects of light source, Ag doping content and types of bacterias on the antibacterial activity of PANI/Ag-TiO2 fibrous nanocomposites were investigated. The results show that the PANI/Ag-TiO2 fibrous nanocomposites have excellent antibacterial activity under the dark light, which is further improved under long-wave UV condition. With the concentration of 1 mg/mL, the sterilization rate to 4 kinds of bacterias of the PANI/Ag-TiO2 nanocomposites can reach 99.99% averagely under the dark light.
