The effect of electrothermopolarization (ETP) on the structure and electrophysical properties (electret, dielectric) of polymer nanocomposites based on HDPE and hafnium oxide nanoparticles has been studied. The possibility of significant change in dielectric properties of HDPE/HfO2 polymer nanocomposites at 3-7% nanoparticle concentration has been confirmed. The interactions of the polymer and nanoparticles are considered and the results of changes in the structure of HDPE/HfO2 polymer nanocomposite in its volume and interphase zone before and after electrothermopolarization are presented. Spectroscopic studies of nanocomposites show that the introduction of nanoparticles is compatible in the presence of polyethylene. Results acquired via an optical microscope with magnification revealed that the nanocomposite HDPE/HfO2 had a variety of morphology from oval, spherical, polygon, to irregular shapes depending on their snitches HDPE and HfO2. HfO2 affects the structure of the nanocomposites, which is observed by SEM, AFM, DSC and confirmed by infrared spectroscopy (FTIR).
