中文摘要：

利用丁二酸酰基过氧化物分解产生的羧酸自由基与多壁碳纳米管（MWCNTs）进行自由基加成反应，对其侧壁实现羧酸化，并依次对其进行酰氯化、胺化处理，获得侧壁酰胺化的MWCNTs．采用FT—IR，Raman以及UV—Vis光谱对其进行了表征．结果表明：碳管表面接枝上了羧酸基团，且数量较纯化后的碳管有较大幅度的增加，表征其结构缺陷的I（D＋2D）/IG比值增加了0．2，同时酰胺化的MWCNTs紫外可见光谱在320nm处出现了-CONH-键的π→π＊跃迁的吸收峰．

英文摘要：

The free radical addition reaction of multi-walled carbon nanotubes （MWCNTs） with succinic acid acyl peroxides resulted in the addition of carboxylic acid groups to the sidewalls of MWCNTs. And these carboxylic acid groups were converted to acid chlorides and then to amides. Characterizations were carried out by FTIR, Raman and UV-Vis spectroscopy. The results indicated that carboxylic acid groups were covalently attached on the sidewalls of MWCNTs, and the number of carboxylic acid groups was increased compared with the purified carbon nanotubes. The ratio of I（D＋2D）/IG, which represents the disorder value of MWCNTs, increased by 0.2, and the absorb peak appeared around 320nm on the UV-Vis spectra of acyl functionalized MWCNTs due to π→π＊ transition of -CONH-bond.
