The review deals with the reasons for the drastic difference between the theoretically derived expectations regarding the mechanical properties of polymer Nano composites and the experimentally obtained results. It is assumed that the most probable reason is the fact that we hardly deal with true Nano composites because in the composites prepared via blending of polymer matrix with the reinforcing Nano-size material the reinforcing elements are not the single Nano particles but their aggregates with sizes in the micrometer range. This situation is due to the fact that currently there are not effective techniques for proper dispersion of Nanomaterial into polymer matrix. The solution suggested is in avoiding the dispersion step in the composite preparation as the “concept of converting instead of adding” does. Two examples of true polymer Nano composites – the Nano fibrillar polymer–polymer and the Nano fibrillar single polymer composites – are described.
