Evaluation of the effect of acid-base nature of inorganic filler on the performance properties of epoxypolymer composite materials

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.
