Seaweed capped zinc oxide nanoparticles (SW-ZnO NPs) were prepared by simple chemical precipitation method of zinc nitrate in the presence of seaweed. The synthesized SW-ZnO NPs were characterised by FT-IR, UV-vis spectroscopy, XRD and BET analysis. These metal oxides were coated on cotton fabric using pad dry cure technique. The SW-ZnO NPs coated cotton fabrics, the surface morphology and chemical composition was analysed by HR-SEM with EDAX. The antibacterial activity of uncoated cotton, seaweed extract and SW-ZnO NPs coated cotton fabrics were investigated against Gram positive (S. aureus and S. pyogenes) and Gram negative (E. coli and K. aerogens). It showed that SW-ZnO NPs coated cotton fabric has higher antibacterial activity than other test samples against both bacteria's. Finally, a UV-protection property of the coated cotton fabric was also tested.
海藻包覆氧化锌纳米粒子（SW-ZnO NPs）是通过在海藻存在下的硝酸锌简单化学沉淀法制备的。合成的 SW-ZnO NPs 通过傅里叶变换红外光谱（FT-IR）、紫外可见光谱、X 射线衍射（XRD）和 BET 分析进行了表征。这些金属氧化物使用轧光干燥法涂覆在棉织物上。通过高分辨率扫描电子显微镜（HR-SEM）和能谱分析（EDAX）分析了 SW-ZnO NPs 涂覆棉织物的表面形貌和化学成分。对未经处理的棉、海藻提取物和 SW-ZnO NPs 涂覆棉织物进行了革兰氏阳性菌（金黄色葡萄球菌和酿脓链球菌）和革兰氏阴性菌（大肠杆菌和产气荚膜梭菌）的抗菌活性研究。结果表明，SW-ZnO NPs 涂覆棉织物对两种细菌的抗菌活性均高于其他测试样品。最后，还测试了涂覆棉织物的紫外线防护性能。
