Confinement Effects on Chain Dynamics and Local Chain Order in Entangled Polymer Melts

What is it about?

Dynamics of polymers confined into ordered nanoporous alumina. In this Communication, we present first results on the degree of anisotropy of segmental orientation fluctuations in entangled and geometrically confined chains in two different types of well-defined model nanocomposites with weakly interacting interfaces. We address temperatures far above Tg and time scales beyond the bulk entanglement time τe, providing a molecular-basis view of the discussed phenomena.
