“…These polymeric transcrystallites grow normally to the surface of the nanodiscs introduced, and a sun-like morphology is observed around the nanodiscs. The transcrystallization phenomenon has been revealed and described previously for PE and for other semi-crystalline polymers [ 25 , 27 , 32 , 33 , 34 ]. It turned out that one and the same nanoparticles cannot act as nucleating agents for all of the polymers.…”

“…The morphology of the drawn nanocomposite fibers (DR = 8) was also examined using the SEM method. It is well known [ 3 , 32 , 33 , 34 , 35 , 36 , 37 , 38 ] that during high-temperature orientational drawing, the lamellae morphology transforms in the fibrillar one. As an example, the SEM micrograph of the internal structure of the fiber with the added nanodiscs is presented in Figure 6 .…”

HDPE-based nanocomposite fibers have been extruded from a melt and drawn up to draw ratio DR = 8. Two kinds of carbon nanodiscs (original ones and those exposed to additional annealing) have been used as fillers. Obtained nanocomposite fibers have been investigated with the help of different experimental methods: rheology, SEM and WAXS. It has been demonstrated that the annealed carbon nanodiscs possess a nucleation ability that finally leads to strong transformation of the material morphology.
