Abstract
Acid functionalized single walled carbon nanotubes were covalently grafted to chitosan by first reacting the oxidized carbon nanotubes with thionyl chloride to form acyl-chlorinated carbon nanotubes which are subsequently dispersed in chitosan and covalently grated to form composite material, CNT-chitosan, 1, which was washed several times to remove un-reacted materials. This composite has been characterized by FTIR, 13C NMR, TGA, SEM and TEM and has been shown to exhibit enhanced thermal stability. The reaction of 1, with poly lactic acid has also been accomplished to yield CNTchitosan-g-poly(LA), 2 and fully characterized by the above techniques. Results showed covalent attachment of chitosan and chitosan-poly lactic acid to the carbon nanotubes. © 2008 Elsevier B.V. All rights reserved.
