  • Title: Rapid microwave synthesis of chitosan modified carbon nanotube composites.
    Author: Yu JG, Huang KL, Tang JC, Yang Q, Huang DS.
    Journal: Int J Biol Macromol; 2009 May 01; 44(4):316-9. PubMed ID: 19022285.
    Abstract:
    Chitosan modified multi-walled carbon nanotube composites were synthesized under microwave irradiation. The resultant chitosan modified multi-walled carbon nanotube composites were purified by twice adjusting of pH value of the solution and centrifugating in succession. The surface functional groups of chitosan modified multi-walled carbon nanotube composites are confirmed by Fourier transform infrared spectroscopy and UV-vis spectroscopy. Transmission electron microscopic images further show the morphologic changes of the carbon nanotubes. Thermal gravimetric analysis shows that the chitosan content in the chitosan modified multi-walled carbon nanotube composites is much higher than conventional methods. The whole reaction procedure can be completed in 1 h under microwave irradiation.
