【摘要】 以黏胶纤维和自制纳米金溶液为原料,采用浸渍吸附法制备不同载金量的载金黏胶纤维;采用扫描电镜、X-射线衍射等手段对载金黏胶纤维的表面结构进行表征和分析,研究了载金黏胶纤维的吸湿性能、力学性能及抗菌性能。结果表明,纳米金以单质金的形式均匀负载在黏胶纤维上,最高负载质量分数可达2 785 mg/kg;载金前后黏胶纤维的吸湿性能和力学性能变化较小;载金黏胶纤维具有良好的抗菌性能,当载金质量分数达到1 500 mg/kg时,载金黏胶纤维对大肠杆菌和金黄色葡萄球菌的抑菌率均可达90%以上。更多还原

【Abstract】 In this paper,gold-loaded viscose fibers were prepared via impregnation adsorption method by immersing viscose fibers into lab made nanogold solution. Structure of the gold-loaded viscose fiber was characterized by SEM and XRD.Moisture absorption,mechanical and antibacterial properties were investigated. The results showed that nano-gold evenly distributed on the surface of viscose fibers as metallic gold and the maximum load capacity was up to 2 785 mg / kg. The moisture absorption and mechanical properties of viscose fibers after gold-loading has almost no chang. The gold-loaded viscose fibers showed excellent antibacterial property. When nano-gold content reached to 1 500 mg / kg,the antibacterial rates against both E. coli and S. aureus were over 90%.更多还原
