文摘
- •
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.
