Polarization processes and electric properties in polypropylene / nanoclay compositions of Na+ monthmorillonite type


The work investigates the electret properties and the process of polarization of nanocomposites based on polypropylene (PP) and nanoclays of the Na+ montmorillonite type. Knowing the magnitude of the compensation voltage of the electret, found from the experiment, according to the known formula, the values of the surface density of charges σ accumulated on the surface of electrets during electrothermopolarization are calculated. Due to the fact that polyolefins containing nanoclay additives have electret properties, it is of scientific and practical interest.
