Abstract
The paper considers the possibility of controlling the interfacial interactions of molecules of polar oligomers and the substrate by forming modified supramolecular structures as a result of acid-base interaction of components of the polymer matrix with the surface of nanodispersed oxides. The effect of aluminum oxide on the properties of ED-20 epoxy resin in the presence of the iso-ITA hardener has been studied: microstructure of oxide samples and acid-base properties of the oxide have been studied; the free energy of the surface and the work of adhesion of the material have been determined from the contact angle.
