Abstract


Background. The latest development in the field of materials to improve the physical and chemical properties is the use of physical modification of polymeric materials. Special attention attracts treatment of external constant magnetic or electric fields of polymeric materials during curing.

Objective.To determine the effects of different natural properties of metal oxides on dynamic mechanical properties of mezocomposites.

Methods. By dynamic mechanical analysis methodstudyof mezocomposite samples filled with oxides of metals, cured by the action of physical fieldswas conducted.

Results. Orientation influence of physical fields changes continuum of molecules involved in the reaction of polyaddition and in the formation of epoxy polymer structure, and leads to the growth of its free volume.  Acquiredelasticity modulus difference is stored in the temperature range of 293–340 K, and when the temperature increases, due to the transition to highly polyepoxy state, the orientation influences of physical fields are lost. Samples were formed under the influence of physical fields are characterized by much higherelasticity modulus values compared with samples formed under normal conditions. Temperature dependence modules losses of epoxy polymer and composites filled with oxides of metals cured under different conditions coincide.

Conclusions. Rationality involvement of acid-base properties to crystal structure aimed modification, thermophysical, dielectric and dynamic mechanical properties of mezocomposites is shown.
