Metal-Containing Nanocomposites on the Basis of Isotactic Polypropylene

摘要

The influence of additions of nanofillers (NF) containing nanoparticles of copper oxide stabilized by a polymer matrix of polyethylene of high pressure, prepared by a mechanochemical method, on peculiarities of the structure and properties of mixed thermoplastic elastomers on the basis of isotactic polypropylene (PP) and ethylene propylene elastomer of double (EPM) and triple (EPDM) by the methods of X-ray diffraction (XRD), scanning electron microscopy (SEM), and thermographical (TGA) analyses has been investigated. It has been shown that an introduction of metal-containing NF in PP/EPDM leads to the formation of fine-spherulitic structure of the filled composition and thereby to improvement of fluidity and thermal-oxidative stability, and in the case of PP/EPM, the physicomechanical properties are improved, and the composition does not flow. Mixture of TPE on the basis of PP/EPM/NF can be processed only by the method of pressing and on the basis of PP/EPDM/NF both by the method of pressing and by the methods of casting under pressure and extrusion, which expands the sphere of its application.
