We introduce the concept of structural affinity of the components of polymer/carbon nanotube nanocomposites quantitatively estimated in the framework of fractal analysis. The affinity of the components significantly affects the characteristics that are essential for nanocomposites, that is, the level of interfacial adhesion and the degree of aggregation of the nanofiller. This means that the degree of affinity completely determines the elastic modulus of the nanocomposite at a fixed concentration of the nanofiller. In turn, this indicator is determined by the structure of carbon nanotubes in the polymer matrix. The creation of high-modulus nanocomposites requires achieving full (or close to it) affinity of the components of these nanomaterials.
