- •
The content of β-crystal in neat iPP was enhanced with increasing number of (LME).
- •
The content of β-crystal in OMMT/iPP composites was decreased with increasing number of LME.
- •
The dispersion of OMMT in iPP matrix was improved by increasing shear force.
- •
The dimensions of OMMT particles influenced the morphology of iPP crystal.
- •
A schematic was proposed to describe the formation mechanism of α-crystal and β-crystal.
