title = "Substrate effects on the confined crystallization of polycaprolactone in coextruded nanolayered films",
abstract = "Layer multiplying coextrusion was used to create multilayered films with hundreds or thousands of alternating layers of two polymers. This paper examines the structure-property relationships of poly(ε-caprolactone) (PCL) nanolayers confined by a variety of polymer substrates. AFM, gas transport and WAXS characterizations were utilized to demonstrate that confined PCL nanolayers crystallized as large in-plane lamellae of high aspect ratio. This phenomenon, previously observed only for poly(ethylene oxide) (PEO), may be a more general phenomenon of crystalline polymers. In-plane PCL lamellae were as effective as PEO in reducing the oxygen permeability by more than 2 orders of magnitude. Additionally, the confining polymer substrate was found to affect to orientation of the PCL nanolayers due to chemical compatibility or epitaxial induced crystallization.",
