Abstract
We study the structure and thermomechanical properties of systems based on epoxy polymer, metal oxides, and polyaniline. It is shown that iron oxide in a mixture with polyaniline begins to reveal its crystalline structure in the composite for a fairly low concentration level (1.0 vol.%) unlike aluminum oxide, which does not reveal its structure even for its high contents. The investigations reveal a strong dependence of the microheterogeneous structure of composites on the type of metal atoms in oxides. By the method of thermomechanical analysis, we show that the composites based on the epoxy polymer and a mixture of polyaniline with one of the metal oxides ( Al2O3 or Fe2O3) are characterized by the abnormal expandability (α1 = 25%).
