Abstract

We present results of Raman studies of CNT-Ni films obtained in two steps method. In the first step an initial nanocomposite Ni-C film (produced by PVD method) was prepared. This initial film has multiphase composite-like structure with nanograins of fullerenes, amorphous carbon and nickel. In the second step CNTs were obtained by CVD method. In this process the initial films were placed in a quartz tube reactor where pyrolysis process were performed in xylene. Decomposition of xylene at 650°C was occurred. Products of this CVD decomposition process take part in nanotubes growth on Ni nanograins. These nanograins play a role of a catalyser of the growth process. SEM observations showed that form of nanotubes obtained with the various CVD process parameters is similar. Raman studies of initial films (obtained PVD process) confirm the presence of fullerenes C₆₀ in and some forms of graphite–like objects in the samples. Raman spectra of MWCNTs films contained: bands characteristic for carbon nanotube’s vibrations.
