摘要：
We found that the cationic polysaccharide chitosan is an efficient dispersion agent for single-walled carbon nanotubes (SWNTs). The spectroscopic properties of chitosan-SWNTs dispersion are different from sodium dodecyl sulfate (SDS)-SWNTs dispersion in acidic conditions. It has been revealed that chitosan is efficiently protective against the protonation of SWNTs. The dispersion behavior of SWNTs in chitosan solutions will be discussed.
