Scholarcy highlights

  • A novel crystal morphology of isotactic polypropylene is achieved in this study
  • No rings could be found in the exterior of the spherulite
  • This article reports the novel crystal morphology of isotactic polypropylene called α banded spherulites, which were induced by a pressure vibration field and investigated through polarized light microscopy, scanning electron microscopy and atomic force microscopy
  • Results showed that the height profile of banded spherulite along the radius corresponded to the pressure fluctuation in the cavity
  • No rings were found in the exterior of the spherulites, indicating that pressure vibration with a specific intensity was indispensable for the formation of banded spherulites
  • This work provided a new insight into the formation mechanism of banded spherulites induced by a mechanical field
