Key words: rapid expansion of supercritical suspensions, carbon nanotubes, dispersion

The influence of temperature, pressure, dispersion medium, type of single-walled carbon
nanotubes (CNTs) on the degree of CNTs deagglomeration after rapid expansion of
supercritical suspensions (RESS) treatment was studied. It is shown by Raman
spectroscopy and scanning electron microscopy that the highest degree of dispersion in
the RESS process is provided by the use of nitrogen.
