Lamellar structures of banded spherulites of poly(?caprolactone)/poly(vinyl chloride) (PCL/PVC) blends are observed using tapping mode atomic force microscopy (AFM). The surface of the PCL/PVC banded spherulites presents to be concentric periodic ups and downs. The period of the bands corresponds to the extinction rings under the polarized optical microscopy observa-tion. The lamellae with edge-on orientation in the ridges and the flat-on lamellae in the valleys of the banded spherulites are observed clearly. The twisting between the edge-on and flat-on lamel-lae is also observed.

The surface of the PCL / PVC banded spherulites presents to be concentric periodic ups and downs. The period of the bands correspond to the extinction rings under the polarized light microscopy observa- tion. The lamellae with edge-on orientation in the ridges and the flat-on lamellae in the valleys of the banded spherulites are observed clearly. The twisting between the edge-on and flat-on lamel-lae is also observed.
