Popis: | The effect of fillers, metal oxide nanoparticles (Fe3O4, ZnO), on the thermal oxidation resistance of polyethylene inhibited by the phenolic antioxidant Irganox 1010 was studied. The distribution of nanoparticles in the polymer matrix was carried out by ultrasound, and the samples were formed by thermal pressing. Thermal oxidation resistance was determined by the duration of the induction oxidation period of film samples. It is shown that the pressure of the press during the formation of the material has a significant effect on the thermal oxidation resistance of the inhibited composite, both filled with nanoparticles of Fe3O4, ZnO, and unfilled. The nature of the effect of the concentration of the nanofiller on the thermal oxidation resistance of the samples depends on the metal oxide used. An increase in the concentration of the filler Fe3O4 leads to a decrease in the thermal oxidation resistance of the polymer; when using ZnO, this dependence is inverse. The oxidation of the prepared nanocomposite film samples formed under high pressure conditions revealed synergistic effects of nanofillers and antioxidants. |
