Atomic force microscopy was used to study the lamellar organization and development in isotactic polypropylene (iPP). The structure and crystallization kinetics were investigated with its hedritic morphology in β (hexagonal) form. The lamellar architecture observed explains the optical birefringence; hedritic objects develop into a spherical envelop by the lamellae splaying consecutively around three axis; curved lamellar habit is frequently observed; the growth proceeds mainly by the branching, diverging and twisting of the lamellae around screw-dislocations.
