酸处理

After removing the catalyzer by dense muriatic acid, carbon nanotubes are reacted with mix acid (vitriol:nitric acid=3:1 vol./vol.). By comparing the surface image of gained carbon nanotubes under the different condition, the best mix acid oxidation temperature is fixed on 140°C and the reaction time is 30min. The soluble carbon nanotubes were prepared by decorating of octadecylamine on the surface of nanotubes. Three processes of grafting were investigated in this research.
