Strongly segregated polyethylene-b-polystyrene (PE-b-PS) diblock copolymers were infiltrated within anodic aluminum oxide nanoporous templates (AAO) (with 60 nm diameter).After carefully removing the nanofibers from the nanopores, TEM revealed their morphology.This is the first time that the morphology of semi-crystalline diblock copolymers infiltrated within AAO templates is observed.Regardless of their composition and initial phase segregated morphology (i.e., lamellae,cylinders or spheres), the infiltrated nanofibers are constituted by core-shell (see Figure 1) or pseudo core shell self-assembled nanocylinders.
