Shear dynamics of ultrathin polymer films

Research output: Contribution to journalConference articlepeer-review


We describe a study of the dynamic oscillatory shear response of liquid films so thin that their thickness is comparable to molecular dimensions. The results raise many questions concerning the packing and crowding of fluid molecules in constricted geometries. In particular, we find that the energy dissipation in sinusoidal shear oscillation between parallel plates is considerably enhanced over that of the isotropic fluid. It shows a remarkable dependence on pressure. A phase transition to a solid-like state is suggested.
