Abstract

This study presents a critical evaluation of the effect
of two different sample manufacturing techniques on the
morphological and dielectric properties of polypropylene (PP)-
based nanocomposites, namely mini-scale injection molding (IM)
vs. pilot-scale cast film extrusion. Polarized light microscopy
revealed that the IM specimen morphology exhibited a layered
“skin-core” type morphology, largely differing from the
spherulitic morphology of the corresponding extruded cast films.
Higher degree of crystallinity in the IM specimens was evidenced
by calorimetric and X-ray diffraction methods. The processingdependent morphological differences were found to affect the
isothermal charging current (ICC) and thermally stimulated
depolarization current (TSDC) characteristics due to differences
in charge mobility and trapping, thus making direct comparison
of IM and cast film specimens non-straightforward. Nevertheless,
mini-scale injection molding can be seen as a resource-efficient
sample manufacturing method for facilitating early-stage
screening of the best-performing material candidates, given that
the morphological features are carefully taken into account.
