Abstract

Green synthesis of selenium nanoparticles (SeNPs) using aqueous ginger extract was prepared for finishing of cellulosic fabrics in presence or absence of titania nanoparticles (TiO₂NPs) for antibacterial and self-cleaning applications. The synthesized nanoparticles were evaluated using transmission electron microscopy (TEM), UV–visible (UV–VIS), and dynamic light scattering (DLS) measurements. The prepared SeNPs@Ginger and TiO₂/SeNPs@Ginger suspensions were used to finish 100% cotton (CO), 50/50% cotton/polyester (CO/PET), linen, and viscose fabrics using pad/dry/curing method for acquiring antibacterial and self-cleaning properties. The finished fabrics were investigated using FTIR, scanning electron microscopy, and energy dispersive X-ray spectroscopy. Antibacterial performance of the finished fabrics against two strains of both Gram-positive and Gram-negative bacteria was evaluated using colony counting method. The results indicated enhanced bacterial inhibition ranging from 42.96 to 86.36% depending on the kind of finished fabrics and tested bacterial species. The photodegradation of dyed fabrics with methylene blue (MB) dye under sunlight irradiation showed sharp decrease of color strength (K/S) from about 6.75 to 0.54 for SeNPs@Ginger finished fabrics and from 7.79 to 0.44 for TiO₂/SeNPs@Ginger treated ones. The photodegradation of methylene blue dyed fabrics showed enhanced self-cleaning performance of the finished fabrics.

生态友好合成硒和二氧化钛纳米颗粒介导的抗菌和自清洁纤维素织物

利用生姜水提物制备绿色合成纳米硒（SeNPs），用于纤维织物在有或没有二氧化钛纳米粒子（TiO2NPs）的情况下进行抗菌和自清洁。通过透射电子显微镜（TEM）、紫外可见（UV-VIS）和动态光散射（DLS）测量对合成的纳米颗粒进行了评价。制备的SeNPs@Ginger和TiO2/SeNPs@Ginger悬浮液用于100%棉（CO）、50/50%棉/聚酯（CO/PET）、亚麻和粘胶织物，采用垫/干/固化法整理，获得抗菌和自清洁性能。利用红外光谱、扫描电镜和能量色散x射线能谱对织物进行了研究。采用菌落计数法评价织物对革兰氏阳性菌和革兰氏阴性菌的抑菌性能。结果表明，根据织物种类和细菌种类的不同，细菌抑制率在42.96% ~ 86.36%之间。亚甲基蓝（MB）染料染色织物在日光照射下的光降解表明，SeNPs@Ginger整理后织物的色强（K/S）从6.75左右急剧下降到0.54，TiO2/SeNPs@Ginger处理后织物的色强（K/S）从7.79下降到0.44。对亚甲基蓝染色织物进行光降解后，织物的自清洁性能得到增强。

期刊介绍： Cellulose is an international journal devoted to the dissemination of research and scientific and technological progress in the field of cellulose and related naturally occurring polymers. The journal is concerned with the pure and applied science of cellulose and related materials, and also with the development of relevant new technologies. This includes the chemistry, biochemistry, physics and materials science of cellulose and its sources, including wood and other biomass resources, and their derivatives. Coverage extends to the conversion of these polymers and resources into manufactured goods, such as pulp, paper, textiles, and manufactured as well natural fibers, and to the chemistry of materials used in their processing. Cellulose publishes review articles, research papers, and technical notes.
