The point-like nuclei gradually form spherulites during the growth process. Oriented nuclei form oriented structures during the growth process, such as skeletals that are strongly dependent on orientation during crystallization.
WebAfter the nucleation step, the sample was ballistically heated to the development-stage temperature of 100 °C (red segment), to allow the nuclei formed in the nucleation stage, as well as any other nuclei, to growth within 20 min to countable spherulites. After rapid cooling and freezing the system, POM images were recorded.
