Electron microscope and electron diffraction have been used to study epitaxial crystallization of poly (ε-caprolactone) (PCL). on highly oriented film of isotactic polypropylene (iPP). The results obtained from bright field (BF) electron micrograph and electron diffraction indicate that the PCL can epitaxially grow on iPP substrate and form cross-hatched lamellar texture. The c axes of PCL are ±50° apart from the c axes of iPP. The contact planes of the two kinds of crystals are (010) of iPP and (100) of PCL, respectively.
