Antimicrobial Performance of Sole Leather Loaded with Zinc Oxide Nanoparticle

ABSTRACT

Natural leather still represents great importance among the materials used by humans in modern times, although it is the oldest-known fiber used by humans. Adding new features to the leather, such as bacteria and fungi resistance, electrical conductivity and magnetic properties, is an ambitious goal for leather developers. In our study, production and characterization of anti-microbial sole leather coated with zinc oxide nanoparticles were achieved. For this purpose, the ZnONPs have been prepared through green synthesis and the prepared nanomaterial loaded on the sole leather by a padding mangle. The surface morphology of the nano coated sole leather was studied using a scanning electron microscope (SEM). Antimicrobial performance of the treated leather to some microorganisms was evaluated by applying the qualitative agar disc diffusion method. The SEM image of the treated leather samples showed successive leather coating, and the nanoparticles completely adhere to the leather surface. The nano-treated leather samples showed significant resistance to the tested bacteria and fungi. Results are promising for the utilization of zinc oxide nanoparticles as additives for sole leather coating. Accordingly, the study succeeded in producing a natural microorganism-resistant sole leather, which can be used in the production of healthy and microorganisms-resistant shoes.

摘要

天然皮革在现代人类使用的材料中仍然占有重要地位，尽管它是已知人类使用的最古老的纤维. 为皮革添加新的功能，如抗细菌和真菌、导电性和磁性，是皮革开发商的一个雄心勃勃的目标. 在我们的研究中，实现了用氧化锌纳米颗粒涂覆的抗微生物鞋底革的生产和表征. 为此，通过绿色合成制备了ZnONPs，并通过填充机将制备的纳米材料负载在鞋底皮革上. 采用扫描电子显微镜（SEM）对纳米涂层鞋底革的表面形貌进行了研究. 采用定性琼脂扩散法评价了处理后皮革对某些微生物的抗菌性能. 处理后的皮革样品的SEM图像显示连续的皮革涂层，并且纳米颗粒完全粘附在皮革表面. 纳米处理的皮革样品对测试的细菌和真菌表现出显著的耐药性. 研究结果对纳米氧化锌作为鞋底涂料添加剂的应用前景广阔. 因此，本研究成功地生产出了一种天然的抗微生物鞋底革，可用于生产健康、抗微生物的鞋.
