Abstract

Fiber based antibacterial materials have gained an enormous attraction for the researchers in these days. In this study, a novel Sericin Encapsulated Silver Nanoclusters (sericin-AgNCs) were synthesized through single pot and green synthesis route. Subsequently these sericin-AgNCs were incorporated into ultrafine electrospun cellulose acetate (CA) fibers for assessing the antibacterial performance. The physicochemical properties of sericin-AgNCs/CA composite fibers were investigated by transmission electron microscopy (TEM), field emission electron microscopy (FE-SEM), Fourier transform infrared spectroscopy (FTIR) and wide X-ray diffraction (XRD). The antibacterial properties of sericin-AgNCs/CA composite fibers against () and () were systematically evaluated. The results showed that sericin-AgNCs incorporated in ultrafine CA fibers have played a vital role for antibacterial activity. An amount of 0.17 mg/mL sericin-AgNCs to CA fibers showed more than 90% results and elevated upto >99.9% with 1.7 mg/mL of sericin-AgNCs against . The study indicated that sericin-AgNCs/CA composite confirms an enhanced antibacterial efficiency, which could be used as a promising antibacterial product.

摘要

如今，基于纤维的抗菌材料已引起研究人员的极大关注。在本研究中，通过单锅绿色合成路线合成了一种新型的丝胶蛋白包裹的银纳米簇（丝胶蛋白 - 银纳米簇）。随后，将这些丝胶蛋白 - 银纳米簇掺入超细静电纺丝醋酸纤维素（CA）纤维中，以评估其抗菌性能。通过透射电子显微镜（TEM）、场发射电子显微镜（FE - SEM）、傅里叶变换红外光谱（FTIR）和宽X射线衍射（XRD）研究了丝胶蛋白 - 银纳米簇/CA复合纤维的物理化学性质。系统评估了丝胶蛋白 - 银纳米簇/CA复合纤维对（）和（）的抗菌性能。结果表明，掺入超细CA纤维中的丝胶蛋白 - 银纳米簇在抗菌活性方面发挥了至关重要的作用。对于CA纤维，0.17 mg/mL的丝胶蛋白 - 银纳米簇显示出超过90%的抗菌效果，而对于（），1.7 mg/mL的丝胶蛋白 - 银纳米簇抗菌效果提升至>99.9%。该研究表明，丝胶蛋白 - 银纳米簇/CA复合材料具有增强的抗菌效率，有望成为一种有前景的抗菌产品。
