SINOPSIS

It has been shown that the efficiency of transfer of mechanical stress applied to the specimen from the polymer matrix to the nanofiller is defined by the structure of carbon nanotubes. The use of the percolation model of reinforcement demonstrated that the considered polymer/carbon nanotubes nanocomposites belong to different types of these nanomaterials, i.e., true and intermediate nanocomposites that are reinforced by the interphase regions only and the interphase regions and the nanofiller, respectively. With the same nanofiller content, the increase of the modulus of elasticity is substantially higher for true nanocomposites compared to intermediate ones.
