| Physicochemical properties of carbon nanotube surfaces by means of the special thermogravimetry (Q-TG), sorptometry and atomic force microscopy (AFM) methods were investigated. A numerical and analytical procedure for the evaluation of total heterogeneous properties (desorption energy distribution and pore-size distribution functions) on the basis of liquid thermodesorption from the sample surfaces under the quasi-equilibrium conditions and sorptometry techniques are presented. The desorption energy distribution was derived from the mass loss Q-TG and the differential mass loss Q-DTG curves of thermodesorption of pre-adsorbed polar and apolar liquid films. For the first time, the evaluation of the fractal dimensions of nanotubes using the sorptometry, Q-TG and AFM data are presented. |
