In this work are presented results of experiments on the synthesis of carbon nanostructures by the method of thermal chemical vapor deposition using copper films as catalysts. The effect of temperature and pressure on the nucleation and stable growth of carbon nanostructures were studied. To determine the optimal conditions for the synthesis, experiments were conducted at different temperatures (200-700 °C) and pressures (100-500 mbar). Experiments have shown that the lower temperature limit for stable growth of carbon nanostructures is 225 °C at pressure of 300 mbar. The morphology of obtained samples was investigated by means of ultrahigh resolution scanning electron microscopy. Likewise, obtained carbon nanostructures were investigated by Raman spectroscopy. Samples showed peaks D and G inherent carbon materials. Furthermore, peaks are present at 1428 cm-1 which correspond to the CH3 group.
