摘要：
The morphology and composition of organic montmorillonites are critical for their dispersion in polymer matrixes. In the current study, the pristine montmorillonite (MMT) was first surface modified with silane and then intercalated using two kinds of intercalating agents in supercritical carbon dioxide (scCO(2)). The obtained OMMTs with tunable morphology and composition, together with pristine MMT and commercial MMT, were introduced into poly(butylene terephthalate) (PBT) to investigate the MMTs dispersion in the PBT matrix and the final properties of the PBT/MMT nanocomposites. The structure of the different MMTs and their dispersion in the PBT matrix were characterized by SEM and TEM, respectively. The crystallization behavior, storage moduli and loss factors of the PBT/MMT nanocomposites were also investigated.
