Abstract
The bulk polymerization of N-vinylcarbazole (NVC) at an elevated temperature in the presence of carbon nanotubes (CNTs) leads to the formation of new type of composite materials, whose morphology and properties were characterized by field-emission scanning electron microscopy (FE-SEM), Fourier transform infrared (FTIR) spectroscopy, Raman spectroscopy, X-ray photoelectron spectroscopy (XPS), thermogravimetric analysis, and electrical property measurements. Using both multi-walled CNTs (MWCNTs) and singlewalled CNTs (SWCNTs), the efficiency of CNTs to initiate the NVC polymerization was investigated by focusing on three major aspects: the degree of polymerization, the morphology, and the properties of resulting nanocomposites. Results showed that SWCNTs were much efficient to initiate NVC polymerization than MWCNTs, and the morphology of resulting nanocomposites revealed the wrapping as well as grafting of some PNVC chains on the SWCNTs surface, whereas the morphology of the PNVC/MWCNTs nanocomposite showed only homogeneous wrapping of MWCNTs outer surface by PNVC polymers.
