摘    要:金属纳米粒子一纤维素复合材料是一种具有生物相容性和抗菌性的可再生纳米材料,由于其应用功能广泛而备受关注。本文首次研究了不使用还原剂条件下’采用微波原位合成法在丁EMPO(2,2,6,6一四甲基哌啶氧化物自由基)选择性氧化黄麻纤维上简便、快速制备银纳米粒子。微波加热5min,纤维上的银纳米粒子平均尺寸为50.0±2.0hm,而加热10min则为90.0±4.7nm。该多功能黄麻一银纳米粒子复合物具有优异的热稳定性和高结晶度。

关 键 词:黄麻纤维  TEMP0  选择性氧化  银纳米粒子  原位合成

In situ growth of silver nanoparticles on TEMPO-oxidized jute fibers by microwave heating
Abstract: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-l-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.
Keywords:jute fibers  TEMPO  selective oxidation  silver nanoparticles  in situ growth
