AbstractNanostructured gratings of semicrystalline polymers like poly(propylene azelate) (PPAz) or of ferroelectric copolymers of vinylidene uoride(VDF) and triuoroethylene(TrFE) have been prepared over spin-coated thin lms by Nanoimprint Lithography (NIL). The structure and morphology of the gratings have been investigated by combining Atomic Force Microscopy (AFM) and Grazing Incidence X-ray Scattering at small angle (GISAXS) and wide angle (GIWAXS). The results reveal that NIL aects signicantly the orientation of the crystalline lamellae. In both cases gratings are more abundant in edge-on lamellae than the reference non-printed lms. For PPAz we attribute this eect to the preferential crystallization as at-on lamellae on silicon surfaces either the stamp trench walls or the substrate surface. Thus, the at-on lamellae on the trench walls appear to be edge-on lamellae in the printed sample. These results further support NIL as an appropriate procedure in order to control polymer crystal orientation.
