| Abstract: | Polypropylene/attapulgite(PP/AT) nanocomposites were prepared by melt-compounding. The nonisothermal crystallization kinetics of polypropylene(PP) and PP/AT nanocomposites were investigated by differential scanning calorimetry(DSC). The Jeziorny, Ozawa and Liu methods were employed to analyze the DSC data. The results show that both Jeziorny method and Liu method could describe this system very well. The activation energies of the nonisothermal crystallization of PP and PP/AT nanocomposite evaluated by Arrhenius equation were 194.1 kJ/mol and 162.8 kJ/mol, respectively. Compounding with attapulgite decreases the activation energy of crystallization of PP. Attapulgite could be used as nucleating agent in nonisothermal crystallization process of PP. |
