摘要：
In this paper we considered three methods of carbon nanotube (CNT) synthesis: chemical vapor deposition in a fixed and fluidized bed rector, and pyrolysis of nebulized solutions of ferrocene in carbon precursor solvents. The latter method has a high CNT yield and allows multiwalled (MWCNTs) as well as single-walled nanotubes (SWCNTs) to be obtained. The samples were analyzed by scanning electron microscopy and Raman spectroscopy. The optimal technological conditions giving a maximum yield of CNTs were studied. A CNT-copper composite was obtained by electroplating or by electroless Cu deposition on the SWCNT layer. MWCNTs were grown on silica fibers and electrical properties of the composite were measured. It was found that electrical resistance of the composite is pressure dependent and its conductivity can be easily varied changing the conditions of synthesis.
