Application of the phase imaging and force modulation SPM techniques for description of the dispersion of multiwalled carbon nanotubes (MWCNTs) in polyol (polyester diol- PED) matrix is presented. The MWCNTs-PED mixture is used to prepare polyurethane (PUR) nanocomposites. Dispersion of MWCNTs in PUR depends on the dispersion of carbon nanotubes in polyol. It is very important to evaluate the degree of homogeneity of the investigated materials. The phase imaging and force modulation microscopy connected with tapping mode allow collecting not only topography images but also images of mechanical properties of a material (hardness, adhesion, friction). By using these SPM modes, it is possible to distinguish structural elements of the mixture and hence to obtain direct information about the distribution of MWCNTs in PED matrix.
