Excellent mechanic and elastic properties of carbon nanotubes (CNT's) make them an attractive candidate as a component of composite materials. Because of the tendency of CNT's to bundle together the main issue is to obtain composite materials with homogeneous distribution of the CNT's in a metal matrix. In our studies we used Raman spectroscopy to identify CNT's in a Ni-CNT's composite. The Ni-CNT's composite were produced by two kind of deposition techniques, i.e., the chemical reduction and the electrodeposition. To achieve well dispersion, functionalised nanotubes were used. Raman spectra of the composite materials were compared with results from scanning electron microscopy (SEM), and transmission electron microscopy (TEM). New peaks obserwd in Raman spectra beetwen 800 cm-1 and 1200 cm-1 can be interpreted as interaction the COOH groups with the Ni atoms or deformation of the nanotubes in Ni matrix.
