用加热多壁碳管与浓硝酸混合物的方法制备了可溶性的多壁碳管 .在超声作用的帮助下可以把这种酸处理的多壁碳管分散在水中形成一种黑色的水溶胶 .此水溶胶可以与阳离子染料耐尔蓝发生相互作用 ,紫外和荧光光谱的变化表明这种作用的结果是耐尔蓝吸附于胶粒表面 ;进而导致溶胶出现共聚现象 ,并且用电化学方法表征了共聚物 .实验结果显示耐尔蓝通过静电作用和疏水作用吸附于多壁碳管胶粒表面 .
Soluble multi-walled carbon nanotubes were prepared by heating a mixture of multi-walled carbon nanotubes and concentrated nitric acid. This acid-treated multi-walled carbon nanotubes were dispersed in water with the aid of sonication to form a black aqueous sol. Hydrosol can interact with cationic dye Nile Blue, and the change of UV and fluorescence spectra shows that Nile Blue adsorbed on the surface of colloidal particles, which leads to the copolymerization of sol and the electrochemical characterization of copolymerization The experimental results show that Nile Blue adsorbs to the surface of multi-walled carbon nanotube particles through electrostatic interaction and hydrophobic interaction.
