Moelcular dynamics in 2D confinement — •Ciprian Iacob, Anatoli Serghei, Rustem Valiullin, Alexey Khokhlov, Jörg Kärger, and Friedrich Kremer — Institute for Experimental Physics I, University of Leipzig, Leipzig, Germany

Broadband dielectric spectroscopy is employed to study the dynamic glass transition of several glass-forming liquids confined to nanoporous materials with pore sizes smaller than 10 nm. The nanopores are non-intersecting host systems which are prepared by electrochemical anodic etching of a highly doped p-type <100> oriented silicon substrate. The impact of interfacial interaction on the molecular dynamics in 2D confinement is analysed as well by coating the inner surface of the pores with diferent anorganic or organic surfactants.
