Preparation and characterization of polypropylene/clay nanocomposites

Polypropylene/clay nanocomposites were synthesized by melt compounding with Cloisite® 20A nanoclay and three different types of compatibilizer in a twin-screw extruder. Different loading of polypropylene maleic alternated polymer (X-10016), polypropylene maleic terminated polymer (X-10088) and polyp...

The XRD patterns and TEM images showed the intercalation of clay layers in polypropylene (PP) matrix of the PPCNs. XRD patterns showed that PP/X-10016/20A hybrids have the highest d-spacing among the three types of PPCNs but the TEM image showed a heterogeneous dispersion of clay. The presence of terminated MAPP, X-10088 resulted in the most uniform clay dispersion. The crystallization behavior of PPCNs was studied by XRD and differential scanning calorimetry (DSC). Characteristic peaks of the PP α-phase crystallites were observed in the XRD graph of the PPCNs. No traces of PP β-phase and γ-phase crystallites are observed. The crystallinity of PP/X-10016/20A hybrids has no changes whereas the crystallinity of PP/X-10018/20A hybrids and PP/Commercial/20A hybrids increases as the MAPP/clay weight ratio increases.
