AbstractThe crystallization behavior of polycaprolactone (PCL) on the highly oriented polyethylene (PE) substrates was studied by means of optical microscopy (OM), transmission electron microscopy (TEM), and electron diffraction (ED). The results of both OM and TEM observations indicate that PE is a very active nucleation agent for PCL. While a transcrystalline zone of PCL is observed in the boundary area of the PE substrate by optical microscopy, both heteroepitaxy and transcrystallization of PCL on the PE substrates are recognized by TEM observations. It was further found that the transcrystalline zone of PCL in the thin films is composed of two different kinds of crystals, i. e. the edge-on crystalline lamellae at the interface, and the further grown flat-on crystals. In thicker samples, a semi-period lamellar twisting occurs during growth of the transcrystalline crystals.
