Melting and non-isothermal crystallization behaviors of polypropylene and polypropylene/montmorillonite nanocomposites under pressurized carbon dioxide

- Non-isothermal crystallization of PP/montmorillonite nanocomposites under pressured CO2 was studied by using DSC.
- Jeziorny modified Avrami and Mo's methods were applied to analyze the non-isothermal crystallization kinetics.
- Plasticization effect of CO2 delayed the crystallization process.
- Heterogeneous nucleation of montmorillonite was significant on enhancing crystallization rate.
