Cellulose fibers deposited with metallic nanoparticles as one kind of renewable, biocompatible and antimicrobial nanomaterials evoke much interest because of their versatility in various applications. Herein, for the first time, a facile, simple and rapid method was developed to fabricate TEMPO (2,2,6,6-tetramethylpiperidine-1-oxyl radical) selectively oxidized jute fibers in situ deposited with silver nanoparticles in the absence of reducing reagents. The average size of silver nanoparticles deposited on the fibers is 50.0 ± 2.0 nm by microwave heating for 5 min and 90.0 ± 4.7 nm for 10 min heating sample, respectively. The versatile jute-silver nanoparticles nanocomposites with superior thermal stability and high crystallinity would be particularly useful for applications in the public health care and biomedical fields.
纤维素纤维负载金属纳米颗粒作为一种可再生、生物相容和抗菌的纳米材料,由于其在各种应用中的多功能性而引起了广泛的关注。在此,首次开发了一种简便、快速的方法,在没有还原剂的情况下,在 TEMPO(2,2,6,6-四甲基哌啶-1-氧自由基)选择性氧化的黄麻纤维原位沉积银纳米颗粒。通过微波加热 5 分钟和 10 分钟分别制备了负载在纤维上的银纳米颗粒的平均尺寸为 50.0 ± 2.0nm 和 90.0 ± 4.7nm。具有优异热稳定性和高结晶度的多功能黄麻-银纳米粒子纳米复合材料将特别适用于公共保健和生物医学领域的应用。
