The contributors of paper gave information about nanoadhesion influence on structure and properties of particulate-filled polymer nanocomposites. It was shown the existence in polymer particulate-filled nanocomposites of nanoadhesion effect, which consists in enhanced level of polymeric matrix-nanofiller interaction. The nanoadhesion effect influences strongly on macroscopic properties of those nanocomposites, in which it was realised. Appreciation of nanoadhesion effect allows qualitatively and quantitatively to describe exactly nanocomposites reinforcement degree.
