DISPERSIVE ALUMINIUM FILLING MATERIAL INFLUENCE ON THE POLYPROPYLENE STRUCTURE AND PROPERTIES

Annotation

  Electret properties of composite polymer materials on the basis of polypropylene were investigated. Investigations were done by methods of thermostimulated and isothermal relaxation of potential and X-ray diffraction analysis. It is shown that aluminium powder adding in pure polymer improves electret stability of original polymer. By a low-angled X-ray dispersion method it was shown that aluminium surface possesses clearly defined fractal properties. Fractal dimensions values indicate that aluminium surface fractions are rough.
