In situ synthesis of ZnO nanorods on cellulosic chains of cotton fabric was accomplished using natural plant source namely Keliab and zinc acetate. Hierarchical mechanism of nano ZnO generation and deposition on cellulosic chains of cotton fabric was discussed in details and several analytical techniques were used to characterize the formation of nano ZnO wurtzite structure. The morphology, crystal phase, and chemical structure of the fabric were characterized by scanning electron microscope, X-ray diffraction and energy dispersive X-ray spectroscopy. Further, interaction between ZnO and functional groups of cellulosic chains of cotton fabric was studied by Fourier transforms infrared spectroscopy. The influence of zinc acetate and Keliab solution on the self-cleaning activity of the treated cellulosic fabric was investigated with a central composite design based on surface response methodology. The treated fabrics showed self-cleaning activity toward methylene blue degradation under day light irradiation. The optimized treated sample showed high antibacterial efficiency against Staphylococcus aureus and Escherichia coli with enhanced tensile strength and higher crease recovery angle.
采用天然植物来源的诃子和乙酸锌，在棉织物的纤维素链上原位合成了 ZnO 纳米棒。详细讨论了纳米 ZnO 在棉织物纤维素链上生成和沉积的分级机制，并采用多种分析技术对纳米 ZnO 纤锌矿结构的形成进行了表征。通过扫描电子显微镜、X 射线衍射和能谱分析对织物的形貌、晶体相和化学结构进行了表征。此外，还通过傅里叶变换红外光谱研究了 ZnO 与棉织物纤维素链上官能团之间的相互作用。采用基于表面响应方法的中心复合设计研究了乙酸锌和诃子溶液对处理后纤维素织物自清洁活性的影响。在日光照射下，处理过的织物对亚甲基蓝的降解表现出自清洁活性。优化后的处理样品对金黄色葡萄球菌和大肠杆菌具有较高的抑菌效率，同时保持较高的拉伸强度和折痕回复角。
