摘要: 利用液相还原的方法在碳纳米管表面包覆金属银。通过扫描电子显微镜(SEM)对包覆层进行表征和分析,探讨了浓度、温度对包覆层均匀性的影响规律。结果表明,AgNO3、PVP、葡萄糖浓度为均001 mol·L-1,反应温度为80 ℃时,碳纳米管表面形成了完整均匀的银包覆层。

Abstract: The method of aqueous reduction is used to prepare a layer of sliver on the surface of carbon nanotubes (CNTs). The cladded carbon nanotubes are characterized by scanning electron microscopy (SEM). The effects of concentration and temperature on uniformity of the coating layer were explored. The results showed that a complete cladding layer was formed on the surface of CNTs when AgNO3, PVP, glucose concentrations were all 001 mol·L-1, and the reaction temperature was 80 ℃.
Key words: carbon nanotubes; surface modification; aqueous reduction method; silvercoated
