AbstractLinkam CSS450 optical shearing stage, wide-angle X-ray diffraction (WAXD) and small-angle X-ray scattering(SAXS) were used to investigate the effect of shear on crystal structure and crystallization morphology of the glass bead filled polypropylene( PP). The results indicate that the glass bead worked as nucleating agent for the glass bead filled PP, compared with pure PP it restrained the formation of beta-crystal after shear treatment. When the mean size of glass bead is smaller(4 mu m) shear rate had less effect on the formation of beta-crystal of PP obviously. However, when the mean size of glass bead is larger(35 mu m), it was found that 20 s(-1) is an optimal shear rate for the formation of beta-crystal. Both shear and glass bead addition could induce the orientation of the lamella of the glass bead filled PP. The higher the shear rate and the bigger the glass bead, the higher the orientation of the lamella was.
