英文摘要 | Polybutylene terephthalate (PBT)/montmorillonite (MMT) nanocomposites were prepared by solution intercalation method. The caly was organo-modified with intercalation agent of cetylpyridinium chloride (CPC). Wide-angle X-ray diffraction (WAXD) indicated interlayer spacing of organoclay in the nonocomposites depends on the amount of organoclay. From the results of differential scanning calorimetry (DSC) analysis it was found that clay behaves as a nucleating agent and enhances the crystallization rate of PBT. The Maximum enhancement of the crystallization rate for the nanocomposites was observed in nanocomposites containing about 5 wt% organcolay with a range of 1-15 wt%. From thermogravimetric analysis (TGA), we found that the thermal stability of the nanocomposites was enhanced by the addition of 1 wt% of organoclay. The thermal stability of PBT/organoclay nanocomposites is related to the organoclay content and the dispersion in the PBT matrix. |
