摘要

本研究报告了一种简单实用的方法，即通过浸渍工艺用二硫代氨基甲酸盐（DTC-Ct）、二硫代氨基甲酸盐-铜（Cu-Ct）和二硫代氨基甲酸盐-镍（Ni-Ct）复合物强化棉织物，从而制备出耐用的抗菌织物。傅立叶变换红外分析表明，强化织物中存在与纤维素官能团相对应的特征峰。扫描电子显微镜（SEM）显微照片显示，在强化织物中，未经处理的棉花表面由封闭堆积的光滑质地转变为包裹着金属复合物的粗糙质地。电离辐射 X 图像证实了浸渍的成功，在未经处理的棉花中，C 和 O 的峰值很突出，而在强化后的样品中则观察到了 S、Cu 和 Ni 的额外信号。与未处理棉织物的粗糙表面相比，TEM 图像显示强化棉织物中存在不规则的球形纳米颗粒。经处理的棉织物中，DTC-Ct、Cu-Ct 和 Ni-Ct 的平均粒径范围分别为 2.20-7.32、3.83-28.50 和 2.70-7.32 nm。未经处理的棉织物没有固有的抗菌特性，而强化棉织物对伤寒沙门氏菌、产气肠杆菌、痢疾志贺氏菌和肺炎克雷伯氏菌等菌株的抗菌效果增强，其中 Ni-Ct 强化棉织物的抗菌效果最佳。此外，还通过洗涤测试评估了添加剂在棉织物上附着的耐久性，结果表明，即使经过多次洗涤，棉织物上的附着力仍然很强，在长达五个洗涤周期中都能观察到持续的抗菌抑制作用。

Fortification of cotton fabrics with dithiocarbamate-metal complexes to prepare durable antimicrobial fabrics

In this study, a simple and practical method is reported to fortify cotton fabrics with dithiocarbamate (DTC-Ct), dithiocarbamate-Cu (Cu-Ct) and dithiocarbamate-Ni (Ni-Ct) complexes via impregnation process to prepare durable antimicrobial fabrics. FTIR analysis indicates the presence of characteristic peaks corresponding to cellulose functional groups in the fortified fabrics. SEM micrographs illustrate the transition from a closed-packed, smooth surface in untreated cotton to a rough texture enveloped with metal complexes in fortified fabrics. EDX images confirm successful impregnation, with prominent peaks due to C and O in the untreated cotton, while additional signals of S, Cu, and Ni were observed in the fortified samples. TEM images revealed irregular, spherical nanoparticles within fortified cotton, compared with the rough surface of untreated fabrics. The average size of the treated cotton fabric fell within the range of 2.20–7.32, 3.83–28.50, and 2.70–7.32 nm for DTC-Ct, Cu-Ct and Ni-Ct, respectively. Untreated cotton fabric exhibits no inherent antibacterial properties, whereas fortified cotton fabrics demonstrate enhanced antibacterial efficacy against strains including Salmonella typhi, Enterobacter aerogenes, Shigella dysenteriae, and Klebsiella pneumonia, with Ni-Ct-fortified cotton proving most effective. Furthermore, the durability of additive adhesion to cotton fabrics was evaluated through washing tests, revealing robust adherence even after multiple cycles, with sustained antimicrobial inhibition observed for up to five wash cycles.

期刊介绍： Polyhedron publishes original, fundamental, experimental and theoretical work of the highest quality in all the major areas of inorganic chemistry. This includes synthetic chemistry, coordination chemistry, organometallic chemistry, bioinorganic chemistry, and solid-state and materials chemistry. Papers should be significant pieces of work, and all new compounds must be appropriately characterized. The inclusion of single-crystal X-ray structural data is strongly encouraged, but papers reporting only the X-ray structure determination of a single compound will usually not be considered. Papers on solid-state or materials chemistry will be expected to have a significant molecular chemistry component (such as the synthesis and characterization of the molecular precursors and/or a systematic study of the use of different precursors or reaction conditions) or demonstrate a cutting-edge application (for example inorganic materials for energy applications). Papers dealing only with stability constants are not considered.
