| 摘 要： | 采用硝酸氧化法对多壁碳纳米管(MWNTs)进行了表面修饰,通过红外光谱和热重分析等测试手段对其结构特性进行了分析,并对多壁碳纳米管在水中的分散性进行了研究。结果表明,采用硝酸氧化法在多壁碳纳米管的侧壁成功引入了羧基官能团,羧基含量受硝酸浓度、氧化温度和时间的影响。表面修饰后的多壁碳纳米管在水中的分散性和稳定性明显提高。

| Abstract: | Multi-walled carbon nanotubes (MWNTs) were modified by the nitric acid oxidation method and the structural characteristics of MWNTs were analyzed by IR and TG.The dispersion of MWNTs in water was also studied.The results showed that there were some carboxyl groups on the side walls of MWNTs after nitric acid oxidation,and the content of carboxyl groups was affected by the concentration of nitric acid,oxidizing temperature and time.The modified MWNTs had higher dispersibility and stability in water. |
