摘      要：Poly(vinylidene fluoride)(PVDF)/montmorillonite(MMT)nanocomposites were prepared by melt blending a kind of organically modified montmorillonite with *** morphological structures of the nanocomposites were studied using X-ray diffraction(XRD),transmission electron microscopy(TEM),Fourier transform infrared(FTIR)spectroscopy,and differential scanning calorimetry(DSC).The results indicate that organically modified montmorillonites are in the form of intercalation,exfoliation,and fragments in the PVDF *** the composites,the(001)peak position of MMT was found to shift to a lower angle in XRD patterns,and some MMT fragments could be observed under *** loading was favorable to producing the piezoelectric beta phase in the PVDF matrix and caused internal stress in a *** the same time,the crystallinity and spherulite size of PVDF decreased with the MMT *** induced beta phase is stable even at high temperatures(160℃).For these changes in morphological structures,some possible explanations were proposed based on the experimental results.
