Viscoelastic Thin Films
Surprisingly enough, the properties of thin polymer films can be covered by hydrodynamic equations originally devised for classical liquids, provided that surface slip is properly taken into account. This was the key insight of Chap. 4. However, this is of course not entirely correct—put simply, it depends on the chain length of the polymer. If the polymer properties are brought into play, the thin films display viscoelastic behaviour. Chapter 5 introduces the concepts needed to cover this case and explains how the thin film equations are modified in this case. Finally, the chapter addresses microscopic properties of thin films like the slip length and glassy behaviour.
