| 摘 要： | 在多壁碳纳米管（MWCNTs）表面上修饰壳聚糖,然后以其为模板,以NaOH为沉淀剂,FeCl3.6H2O和CoCl2.6H2O为铁源和钴源,采用水热法在MWCNTs上修饰CoFe2O4纳米粒子。用X-射线粉末衍射、场发射透射电镜、红外吸收光谱以及超导量子干涉磁强计研究了所制备的多壁碳纳米管/壳聚糖/CoFe2O4复合材料的组成、形貌以及磁性,并探讨了反应温度以及FeCl3.6H2O和CoCl2.6H2O浓度对产物的影响。

| Abstract: | The multiwalled carbon nanotube(MWCNT)/chitosan/CoFe2O4 nanocomposites were synthesized by the hydrothermal method using chitosan-wrapped MWCNTs as template,sodium hydroxide as precipitant,FeCl3·6H2O and CoCl2·6H2O as metal ion sources.The resultant nanocomposites were characterized by XRD,TEM,FT-IR spectra and superconducting quantum interference magnetometer.The effect of reaction temperature and charging capacity of FeCl3·6H2O and CoCl2·6H2O on the products were also studied. |
