Abstract

The research delves into the effects of dielectric barrier discharge air plasma on the antibacterial properties of Ocimum sanctum and Camellia sinensis leaf extract-coated corn fabric. Plasma treatment improved corn fabric hydrophilicity by activating the binding of hydrophilic functional groups on the fabric surface. XPS analysis showed increased O/C ratio and -COOH, -CO functional groups post-treatment. FTIR analysis revealed the reduction of lignin and other non-cellulosic impurities. Plasma treatment enhanced the fabric's surface properties, allowing for better adhesion and uniform coating of the bioactive extracts. Antibacterial efficacy was tested against the two most common disease-causing bacteria, Escherichia coli and Staphylococcus aureus, and was confirmed through qualitative and quantitative antimicrobial tests. SEM analysis showed reduced bacterial content on plasma-treated fibres. The antimicrobial finish's durability was assessed after five laundry cycles. The results indicated that incorporating plant extracts into plasma-treated corn fabric provided long-lasting and effective antibacterial strength. A proposed reaction mechanism suggests interactions between the plasma-treated fabric, plant actives and binding agent. This study highlights the synergistic effects of plasma treatment and natural extracts in producing sustainable and bioactive fabric materials with potential applications in medical and healthcare settings.

利用介质阻挡放电等离子体和植物提取物对玉米织物进行协同表面处理，提高抗菌性能

该研究深入探讨了介质阻挡放电空气等离子体对涂有金缕梅和山茶叶提取物的玉米织物抗菌特性的影响。等离子处理通过激活织物表面亲水官能团的结合，改善了玉米织物的亲水性。XPS 分析显示，处理后的 O/C 比和 -COOH, -CO 官能团有所增加。傅立叶变换红外分析显示木质素和其他非纤维素杂质减少。等离子处理增强了织物的表面特性，使生物活性提取物具有更好的附着力和均匀的涂层。抗菌效果针对两种最常见的致病细菌--大肠杆菌和金黄色葡萄球菌进行了测试，并通过定性和定量抗菌测试得到了证实。扫描电镜分析表明，经过等离子处理的纤维上细菌含量减少。经过五个洗衣周期后，对抗菌整理剂的耐久性进行了评估。结果表明，在经过等离子处理的玉米织物中加入植物提取物，可提供持久有效的抗菌能力。所提出的反应机制表明，经过等离子处理的织物、植物活性成分和结合剂之间存在相互作用。这项研究强调了等离子处理和天然提取物在生产可持续生物活性织物材料方面的协同效应，有望应用于医疗和保健领域。

期刊介绍： Industrial Crops and Products is an International Journal publishing academic and industrial research on industrial (defined as non-food/non-feed) crops and products. Papers concern both crop-oriented and bio-based materials from crops-oriented research, and should be of interest to an international audience, hypothesis driven, and where comparisons are made statistics performed.
