中文摘要：

利用非共价修饰的方法,先在碳纳米管表面包裹上表面活性剂十六烷基三甲基溴化铵（CTAB）和聚丙烯酸钠（PAA）,然后原位修饰上铜和银纳米粒子,制备出MWCNT/CTAB/PAA/M（M：Cu或Ag）纳米复合材料,最后通过XRD、SEM和TEM等技术对其进行表征。结果表明,利用这种简单的层层自组装方法能够在碳管上均匀地修饰金属纳米粒子,并且这两种金属纳米粒子的尺寸都小于5 nm。

英文摘要：

Metal nanoparticles（copper or silver） were loaded on the sidewall of MWCNTs by an in situ wet chemical synthesis approach via layer by layer non-covalent functionalization of MWCNTs with cetyltrimethyl ammonium bromide（CTAB） and sodium polyacrylate（PAA）.The resultant of MWCNT/CTAB/PAA/M（M=Cu,Ag） nanocomposites were characterized by XRD,SEM and TEM techniques.The results showed that the CNTs were well modified with the metal nanoparticles and the mean sizes of the particles were less than 5 nm.
