Awareness of microbial infection, hygiene, and personal health has increased in recent years, particularly in light of the pervasive pandemic encountered by the global community. This has prompted the development of antibacterial and superhydrophobic cotton fabric to address the pressing challenge. In this investigation, we report bio-mediated zinc oxide nanoparticles (ZnO NPs) synthesized using leaf extract and zinc acetate. Further, the chitosan-ZnO nanocomposite (CS-ZnO) was synthesized and subsequently deposited on cotton fabric (CF) a facile and cost-effective pad-dry-cure method to produce CS-ZnO-CF. The ZnO NPs, CS-ZnO, and CS-ZnO CF were characterized using FTIR, XRD, SEM-EDAX, TGA and AFM analysis. Additionally, we investigated the mechanical properties and water contact angle (WCA) of uncoated cotton (UCF) and CS-ZnO CF. The CS-ZnO-CF demonstrated good mechanical stability even after 50 abrasion cycles, good washing durability, and good super-hydrophobicity, with a high WCA (153.1°). The antibacterial study indicated that CS-ZnO and CS-ZnO-CF exhibited higher antibacterial activity than UCF against () and () bacteria. This study introduces a simple, environmentally friendly, and economically scalable method for producing multifunctional CS-ZnO CF, showcasing its potential for diverse applications.
近年来，人们对微生物感染、卫生和个人健康的认识有所提高，尤其是鉴于全球社会遭遇的普遍大流行。这促使了抗菌和超疏水棉织物的开发，以应对这一紧迫挑战。在本研究中，我们报告了使用叶提取物和醋酸锌生物介导合成的氧化锌纳米颗粒（ZnO NPs）。此外，合成了壳聚糖-氧化锌纳米复合材料（CS-ZnO），随后通过一种简便且经济高效的浸轧-烘干-焙烘方法将其沉积在棉织物（CF）上，以制备CS-ZnO-CF。使用傅里叶变换红外光谱（FTIR）、X射线衍射（XRD）、扫描电子显微镜-能谱分析（SEM-EDAX）、热重分析（TGA）和原子力显微镜（AFM）分析对ZnO NPs、CS-ZnO和CS-ZnO CF进行了表征。此外，我们研究了未涂层棉（UCF）和CS-ZnO CF的机械性能和水接触角（WCA）。即使经过50次磨损循环，CS-ZnO-CF仍表现出良好的机械稳定性、良好的洗涤耐久性和良好的超疏水性，水接触角高达153.1°。抗菌研究表明，CS-ZnO和CS-ZnO-CF对（）和（）细菌表现出比UCF更高的抗菌活性。本研究介绍了一种简单、环保且经济上可扩展的制备多功能CS-ZnO CF的方法，展示了其在多种应用中的潜力。
