摘　　要：通过CVD法制备碳纳米管,并用浓硝酸和浓硫酸对其酸化处理,然后使用CTAB进行修饰,最后通过结合胶实验进行橡胶补强的研究。实验表明:经过酸化处理,碳纳米管上产生较强的羟基基团,并能将CTAB吸附在碳纳米管周围;CTAB修饰后的碳纳米管的结合胶量比普通炭黑更高。In this experiment, carbon nanotubes （CNTs） prepared by chemical vapor deposition （CVD） were acidized by concen- trated nitric acid and concentrated sulfurie acid. Bound rubber experiment was carried out to investigate the rubber reinforcement by modified CNTs with CTAB. The results indicated that the acidized CNTs have a lot of hydroxyl groups which could absorb CTAB on the surface of CNTs, and the modified CNTs with CTAB have higher content of bound rubber than general carbon black.
