interfacial adhesion

The most typical behaviour features of polymer nanocomposites filled with dispersed calcium carbonate were considered. The quantitative analysis was carried out within the frameworks of structural model: the cluster model of polymers amorphous state structure and fractal analysis. It has been shown that all changes of the considered nanocomposites properties were defined by polymeric matrix structure variations, which are due to nanofiller introduction.

It has been shown that aggregation (tangled coils formation) of carbon nanotubes begins at their very small contents. This factor strongly reduces reinforcement degree of polymer/carbon nanotube nanocomposites. Estimation of the main parameters that influenced elasticity modulus of the mentioned nanocomposites was fulfilled. Theoretical calculations showed high potential of nanocomposites filled with nanotubes.
