Abstract

We study the structure and thermomechanical and electrophysical properties of systems based on epoxy polymers, metal oxides ( Al2O3 or Fe2O3 ), and polyaniline. By the X-ray diffraction analysis, it is shown that, under the action of a constant magnetic field, the period of short-range ordering of the fragments of interstitial molecular links of the epoxy polymer increases. It is demonstrated that the coefficient of linear expansion for the composites formed in constant magnetic fields is much (two times) lower than for ones formed in the absence of magnetic fields; it is also shown that the composites with (PANI, Al2O3 ) and (PANI, Fe2O3 ) mixtures are characterized by the increase in conductivity by 3–4 orders of magnitude.
