Abstract

The molecular dynamics of confined (low molecular weight and polymeric) systems is determined by the counterbalance between surface- and confinement-effects: Due to the interaction with the (inner) surfaces (e.g. the formation of H-bonds, grafting, physisorption) the molecular dynamics is slowed down, resulting in an increase in the glass transition temperature of the system. In contrast the confinement may induce an increase in `free volume' thus making the molecular dynamics faster than in the bulk. This causes a decrease in the glass transition temperature. This counterbalance will be exemplified by employing broadband dielectric spectroscopy (10-2 Hz-109 Hz) to study the molecular dynamics of the low molecular weight liquid ethylene glycol being contained in zeolites of different topology.
