为了探求碳纳米管在水性体系中的有效分散方法及分散性能，以阿拉伯胶（ GA）、曲拉通（ Tx100）、十六烷基三甲基溴化铵（ TB）、十二烷基磺酸钠（ SDS）4种表面活性剂（ SAA）为多壁碳纳米管（ MWNTs）的分散剂，采用SAA超声分散法及酸处理法制备了11种分散液。结合静置离心法研究了不同种类 SAA 单掺的分散效果，结果表明：单掺 GA 对MWNTs分散效果最好，离心170 min后才开始分层。首次采用紫外分光光谱吸光度法评价了不同种类SAA复掺及SAA掺量变化对MWNTs分散性能的影响，测试结果表明：复掺Tx100与GA效果最好；当GA掺量为0．45 g／L时效果最好；比较二者分散效果后知：GA 掺量为0．45g／L 的悬浮液分散效果最佳。采用傅里叶红外光谱（FTIR）检测混酸氧化后MWNTs表面的基团，分析可知：经混酸处理后，MWNTs表面成功引入了羟基和羧基等官能团。

In order to study the effective dispersion method and dispersion properties of carbon nanotubes in the a?queous system, four surfactants?gum arabic( GA) , triton xl00( Tx100) , cetyl trimethyl ammonium bromide( TB) , and sodium dodecyl sulfate( SDS) were individually or combinatorially employed as the dispersants to evaluate the dispersion of multi?walled nanotubes (MWNTs). Combined with ultrasonic treatment and acid treatment, eleven kinds of liquid dispersions were made with surfactant. Observing the dispersion with stewing?centrifugation method, the experimental results showed that GA had the best dispersion impact on MWNTs after the solution had been cen?trifuged for 170 minutes. The UV?vis was first used to evaluate the absorbency variation of MWNTs over time. The test results showed that Tx100 blended with GA had the best effect on MWNTs when the concentration of GA is 0.45g/L variation. The comparison results showed that the suspension of GA with concentration of 0.45 g/L had the best dispersibility. FTIR was used to measure the surface group of MWNTs and the results showed that there were hydroxide radical and carboxyl group on the surface of MWNTs when treated with mixed acid.
