Method for producing films
No full textThe present invention provides a process for producing thin solid films of a substance by drawing a thin liquid film of the substance from a bath, stabilizing the film in a liquid state by inducing a surface tension gradient along the length of the film, and subsequent cooling or curing to form a solid film. The present process permits contact- free thin films to be produced more rapidly than conventional processes, and allows precise control of the final film thickness.info:eu-repo/semantics/publishe

The role of surface rheology in liquid film formation
No full textThe role of surface rheology in fundamental fluid dynamical systems, such as liquid coating flows and soap film formation, is poorly understood. We investigate the role of surface viscosity in the classical film-coating problem. We propose a theoretical model that predicts film thickening based on a purely surface-viscous theory. The theory is supported by a set of new experimental data that demonstrates slight thickening even at very high surfactant concentrations for which Marangoni effects are irrelevant. The model and experiments represent a new regime that has not been identified before.SCOPUS: ar.jinfo:eu-repo/semantics/publishe
