不同应用环境下异质结纺织品抗菌性能的研究
Antimicrobial properties of heterojunction textiles in different application environments
摘要
Abstract
To explore the changes in antibacterial performance of heterojunction textiles in different application environments,Escherichia coli was used as representative bacteria to study the antibacterial rate of heterojunction textiles at different temperatures,pH,light intensity and wavelengths by the oscillation method.The results indicated that environmental factors significantly influenced the antibacterial performance of the heterojunction textiles.The bacteriostatic rate basically increased initially and then decreased with rising temperature.Within the pH range of 3.0～8.0,the heterojunction textiles exhibited strong antibacterial activity,peaking at pH 7.5,with acidic conditions being more favorable than alkaline environments.Light intensity significantly affected its antibacterial efficacy,as the bacteriostatic rate under dark conditions was 36%lower than that at 50 mW/cm2.Additionally,antibacterial effectiveness diminished with increasing wavelength.The heterojunction textiles showed no significant cytotoxicity toward HaCaT cells,and the amounts of released metal elements during oscillation remained below the actually measured levels of metal elements.Compared to untreated polyester fabric,the heterojunction textiles demonstrated significantly enhanced photocatalytic performance.Treated Escherichia coli showed distorted morphology with severe surface depression and significantly increased PI-stained fluorescent spots.After 50 washing cycles,the bacteriostatic rate still reached the AAA level,indicating exceptional antibacterial efficacy and stability.关键词
