Popis: It has been shown that graphene does not have any advantages over organoclay. The main characteristics of 2D nanofillers in a polymer matrix are not related to their initial properties. To realize the extremely high characteristics of polymer/2D nanofiller nanocomposites, it is necessary to create an optimal structure of the nanofiller in the polymer matrix. The aggregation degree and the aspect ratio of the tactoids of the 2D nanofiller are determined by the ratio of the nominal elasticity moduli of the nanofiller and the matrix polymer. The effective elasticity modulus of the nanofiller in the polymer matrix of the nanocomposite is determined by its rigidity.
