ABSTRACT

This study addresses the deposition with improved adhesion of TiO2:N/SiO2 mixture, with different concentrations of the nano-powders (NPs) (1:0,5; 1:1 and 1:1,5) on 100% cotton fabrics. The characteristics of the deposited thin films were investigated by scanning electron microscopy (SEM), Rutherford backscattering spectrometry (RBS), Raman scattering, FTIR, and UV-VIS absorption spectroscopy. To improve the treatment durability to the external factors, the different crosslinking methods were used. Photocatalytic activity of functionalized textile fabrics was evaluated by determining the photodegradation efficiency of the methylene blue (MB) dye and forest juice, measuring the color difference of the irradiated samples compared with non-irradiated samples. Washing durability of the samples was achieved qualitatively by determining the photocatalytic activity remaining on the textile fabrics after 1 and 5 washing cycles. The samples treated with the mixture of TiO2:N/SiO2 have demonstrated improved self-cleaning properties, the highest photocatalytic activity being obtained for the highest value of TiO2:N/SiO2 NPs molar concentrations equal to 1:1.

用 TiO2:N 和 SiO2 纳米粒子的混合物处理纺织材料以提高其自清洁性能

摘要

本研究解决了 TiO 2 :N/SiO 2附着力提高的沉积问题混合物,在 100% 棉织物上具有不同浓度的纳米粉末 (NPs) (1:0,5; 1:1 和 1:1,5)。通过扫描电子显微镜 (SEM)、卢瑟福背散射光谱 (RBS)、拉曼散射、FTIR 和 UV-VIS 吸收光谱研究了沉积薄膜的特性。为了提高对外部因素的处理耐久性,使用了不同的交联方法。通过测定亚甲蓝 (MB) 染料和森林汁液的光降解效率,测量辐照样品与未辐照样品的色差,评估功能化纺织品的光催化活性。通过测定 1 次和 5 次洗涤循环后织物上剩余的光催化活性,可以定性地实现样品的洗涤耐久性。2 :N/SiO 2已显示出改进的自清洁性能,最高的光催化活性是在 TiO 2 :N/SiO 2 NPs 摩尔浓度等于 1:1 的最高值时获得的。
