INVESTIGATIONS ON THE TEXTURE AND SURFACE CHEMICAL STRUCTURE OF THE HOLLOW ACTIVATED CARBON FIBER SNACF
空心活性碳纤维SNACF的织构和表面化学结构的研究

The texture and surfree chemical strneture features of hollow activeted carbon fiber SNACF have been investigated by using techniques TEM, SEM, XPS, IR, X-ray diffraction and chemical titration etc. The experimental results showed that the SNACF is an activated carbon fiber eontainning N and S possessing porosity and microcrystal line-carbon structure with basic functional groups and acid functional groups -COOH phenolic-Oil etc, as well as high- oxidized sulfur such as sulphonic acid functional groups on its surface.
