A novel chitosan fiber core/gold shell structural organic-inorganic composite was presented via a facile and eco-friendly approach. The chitosan fiber and gold/chitosan composites were characterized with the assistance of scanning electron microscopy and transmission electron microscopy observations. The chitosan fibers used in this study were 50 nm to 5 microm in diameter and up to hundreds of micrometers in length. The gold shells were typically 20-50 nm in depth, and their lattice fringes obliquely intersecting at an angle of 60 degrees were displayed. The formation mechanism of the as-fabricated chitosan fiber core with gold as the shell structural composites was also schematically discussed.
通过一种简便且环保的方法制备了一种新型的壳聚糖纤维芯/金壳结构的有机-无机复合材料。借助扫描电子显微镜和透射电子显微镜观察对壳聚糖纤维和金/壳聚糖复合材料进行了表征。本研究中使用的壳聚糖纤维直径为50纳米至5微米，长度可达数百微米。金壳的深度通常为20 - 50纳米，并且展示出其晶格条纹以60度角倾斜相交。还示意性地讨论了所制备的以金为壳结构的壳聚糖纤维芯复合材料的形成机理。
