Change of thermophysical parameters of polypropylene-metal oxide nanocomposite (polypropylene + ZrO₂) after electric field influence

In this work, the influence of an electric field on thermophysical properties of the PP+ZrO2 nanocomposites has been investigated. Changes in thermograms before and after applying an electric field (EFI) have been studied depending on the filler percentage in the polymer matrix. After EFI a new, weak maximum at the temperature range of 100–130°С of the thermograms for all concentrations of the filler was observed. Thermophysical parameters of the nanocomposite sample have been calculated for different values of electric field strengths that were applied are calculated depending on the effect of the ETP.
