The presence of nanoclay platelets in semicrystalline polymers leads to significant changes in their crystallization behavior and polymorphic structure. Therefore, basic understanding of the effect of clay addition on the structural and crystallization behavior of semicrystalline polymers is needed. The semicrystalline polymers studied include polar PA6 and PVDF as well as nonpolar polyolefins. The chapter begins with a brief description of the general properties and dispersion of nanoclays in polymers. Then the influence of clay addition on the polymorphic structure, crystallite morphology, isothermal and nonisothermal crystallization of semicrystalline polymers is discussed in detail. Particular attention is paid to the use of X-ray diffraction, optical microscopy, fourier transform infrared spectroscopy and differential scanning calorimetry techniques for characterizing the crystallization behavior of polymer-clay nanocomposites.
