Abstract

A recently developed experimental platform in polymer nanofluidics [1, 2] is used to investigate the glassy dynamics of phase-separated block-copolymers during capillary flow into cylindrical nanopores. The flow process is monitored by means of broadband dielectric spectroscopy. Due to the break in the symmetry induced by the geometrical confinement, a structural transition in the polymer morphology is observed, no shifts in the position of the dynamic glass transition are detected.
