Download scientific diagram | Micrographs of the cross-section morphology of compression moulded samples after freeze-cracking and acid etching of the amorphous domains. The banded spherulite morphology of directly compression moulded samples from pellets is shown in (a) and (b). The morphology of the samples that had been extruded prior to compression moulding is shown for 10 s extrusion in (d) and for 6 min extrusion in (e). The fractured and etched cross-section of the manufacturer's LDPE is shown (c) from publication: Lamellae-controlled electrical properties of polyethylene – morphology, oxidation and effects of antioxidant on the DC conductivity | Destruction of the spherulite structure in low-density polyethylene (LDPE) is shown to result in a more insulating material at low temperatures, while the reverse effect is observed at high temperatures. On average, the change in morphology reduced the conductivity by a | Polyethylene, Conductivity and Antioxidants | ResearchGate, the professional network for scientists.
