Descripción
The dynamics of monolayers is important in a wide variety of scien- tific and technological fields including medicine, pharmacology, material science, and nanotechnology. In the particular case of Langmuir polymer monolayers, experiments are comonly performed to measure surface rheo- logical properties on which the dynamics is strongly dependent. In these experimental configurations, a shallow liquid layer is slowly compressed and expanded in periodic fashion by moving two solid barriers, chang- ing the free surface area and simultaneosly measuring surface properties. Since the forcing frequency is small, current theoretical studies only in- clude surface phenomena while ignoring fluid dynamics in the bulk. This approximation provides good results only if the dynamics is sufficiently slow. Here we present a long wave theory that does take fluid dynamics into account. This addresses the issue of flow effects in the measurement of surface properties and allows one to determine how small oscillation frequencies should be to obtain accurate values of rheological properties.
