Structure and magnetic properties of mechanochemically synthesized UHMWPE/ferrite composites as precursors for electromagnetic shielding materials

Abstract

In this paper, a study of composite materials based on ultrahigh molecular weight polyethylene (UHMWPE) and magnesium ferrite particles - precursors for electromagnetic shielding materials was carried out. Scanning electron microscopy, X-ray diffraction, Mossbauer and FTIR spectroscopy have been applied to study the influence of structural, morphological and magnetic state of ferrite particles on the composite polymer materials formed by the method of mechanochemical activation in mixtures of ferrites with UHMWPE. It was revealed that synthesis method type showed a significant effect on the size, morphology, crystal structure (inversion parameter) and magnetic properties of ferrite particles. All of these studied parameters determine their functional properties as an independent material, and their properties in the composition of the functional polymer composite material.
