采用硫酸和硝酸对多壁碳纳米管进行化学功能化。用两种不同的酸比率进行官能化。用傅里叶变换红外光谱、X射线光子光谱、热重分析、元素分析、扫描电子显微镜（SEM）和透射电子显微镜对功能化纳米管进行了表征。碳纳米管（CN）的磺化将碳纳米管的电导率增加至1.25 X 10-1 S/cm。样品的SEM显微照片显示，由于颗粒之间的氢键增加，CN以更大的形式存在。CN的zeta电位随着磺化量的增加而增加。
Multi-walled carbon nanotubes (MWCNTs) were chemically functionalized by using sulfuric acid and nitric acid. The functionalization was done with two different acid ratio. The functionalized nanotubes were characterized with Fourier Transform Infrared Spectroscopy, X-Ray Photon Spectroscopy, Thermal Gravimetric Analysis, Elemental Analysis, Scanning Electron Microscopy (SEM), and Transmission Electron Microscopy. Sulfonation of carbon nanotubes (CN) increased the electrical conductivity of carbon nanotubes up to 1.25 x 10-1 S/cm. The SEM micrographs of the samples showed that CN was observed in more bulky form due to the increasing hyrogen bonding between the particles. The zeta potential of the CN increased with increasing sulfonation amount.
