摘要：
Multi-walled carbon nanotubes (MWNTs) were functionalized via oxidative polymerization of 3-3'(vinylcarbazole) (PVK). Thin films of PVK-functionalized MWNTs (PVK-MWNTs) were fabricated by the Langmuir-Schaefer (LS) technique and characterized by spectroscopic, microscopic, electrical and electrochemical techniques before and after doping with iodine. I/V characterization showed an increase in the conductivity of the PVK-MWNTs and I-2-doped PVK-MWNTs compared with the PVK and I-2-doped PVK, respectively. The electrochemical characterization showed the formation of an I-2-doped PVK-MWNT complex. These nanostructured PVK-MWNT films revealed an increase in the current density under illumination of about 500 nA cm(-2).
