| 摘 要： | 采用沉淀析出法,通过加入去溶剂化试剂硫酸钠制备壳聚糖(CS)纳米粒子;通过电化学沉积法制备了Cu2O/CS纳米复合材料.研究表明,随着反应条件的改变,Cu2O能够在CS纳米颗粒上形成针状或球形等不同形貌.电化学沉积机理通过透射电子显微镜、X射线光电子能谱技术对二者的结合机制进行了探讨,为Cu2O/CS纳米复合材料的制备和应用研究提供了理论依据.

| Abstract: | Chitosan （CS） nanoparticles were prepared with the precipitation method by adding sodium sulfate; Cu2O/CS nano-composites were prepared by electrochemical deposition. Experiments 3howed that with the change of the reaction conditions, Cu2O nanoparticles could form needle-like or spherical formations on the surface of chitosan nanoparticles. The electrochemical deposition mechanism was studied with the help of electron microscopy and X-ray photoelectron spectroscopy and it provided the theoretical basis for the preparation and application of the nanocomposite Cu2O/CS. |
