Web15. apr 2024 · The size of PEG inclusions determined by their extraction is around 1 μm. The PEG/PLLA blends exhibited not only spherulites with Maltese crosses but also distinct extinction rings. The formation of ring-banded spherulites and the periodic distance between the rings were related to the degree of supercooling of the polymer. Web31. mar 2024 · A spherulite (organic/inorganic molecular compounds or polymers) is a hierarchically packed complex structure of a rounded aggregate composed of central nuclei usually with cavity/crack, lamellae bundles radiating from nuclei, crystal branches or dislocations, and interspersed with localized amorphous domains.
