Polyphenylene sulfide (PPS)/organic clay nanocomposites were prepared by simple melt
blending. A synthesized benzimidazolium salt was used to modify the sodium montmorillonite
in order to improve the compatibility with the PPS. The nonisothermal crystallization
kinetics of PPS/organic clay composites were investigated by differerntial scanning
calorimetry(DSC). It was observed that the crystallization peak temperature of PPS/organic
clay composites was higher than pure PPS at various cooling rates. Several models such as
the Ozawa and Mo equation were used to characterize the nonisothermal cooling
crystallization kinetics of the PPS/organic clay composites. The results indicated that
the Ozawa equation was not successful, while the Mo equation was successful to describe
the nanoisothermal ctystallization kinetics of PPS/organic clay nanocomposites. The
results also indicated that organic clay not only served as heterogeneous nucleating
agents for PPS crystallization at lower content but also restricted the mobility and
diffusion of PPS chains at higher content. These results were further supported by the
crystallization activation energy of the samples determined by the Kissinger method.
