Dispersion Behavior and Spectroscopic Properties of Single-walled Carbon Nanotubes in Chitosan Acidic Aqueous Solutions
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 c...

Summary: | 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. |
