Description
  • Práce je zaměřena na možnosti mikrofibrilární formace v polymerních směsích během vytlačování přes vytlačovací hlavu se semihyperbolickým sbíhavým kanálem. K tomuto účelu byly připraveny tři směsi polyetylen/polypropylen v poměrech (hm./hm.) 80/20, 70/30 a 60/40. Konečná struktura a vlastnosti vytlačených směsí byly analyzovány pomocí elektronového mikroskopu, širokoúhlé rentgenografie a diferenciální snímací kalorimetrie. Je ukázáno, že ke vzniku mikrofibrilání fázové morfologie došlo ve všech směsích, nezávisle na poměru složek. Nicméně, struktura a vlastnosti těchto mikrofibrilárních kompozitů jsou poměrem složek silně ovlivněny. (cs)
  • The work focuses on the possibilities of microfibrillar-phase formation in polymer blends during extrusion through a die with semihyperbolic-converging channel. For these purposes, three polyethylene/polypropylene blends with the mixing ratios (wt./wt.) 80/20, 70/30 and 60/40 were prepared. Final structure and properties of extruded blends were examined using electron microscopy, wide-angle X-ray scattering and differential scanning calorimetry. It is demonstrated that the formation of microfibrillar-phase morphology is achieved in all the blends, independent of their mixing ratios. However, the structure and properties of these microfibrillar-phase composites are strongly influenced by mixing parameters.
