The non-equilibrium process of the porous polymer film formation: modeling — •Masoud Amirkhani, Farid Farajollahi, and Othmar Marti — Institut für Experimentelle Physik, Universität Ulm

The breath figure (BF) is a very wide spread method for fabricating porous polymer film. The BF is a simple method, which one uses the condensation of water on an evaporating surface of polymer solution to produce porous film or porous surface. In spite of the simplicity of the BF technique, there is not a physical model that can describe the process. This is due to the complexity of the process, which includes evaporation of the solvent, condensation of water droplets, emerging droplets, mass and heat convection. The combination of the mentioned phenomenon leads to a complicated non-equilibrium process that is very sensitive to the initial system parameters (such as polymer concentration, solvent, the structure of polymer and etc.) and environmental condition (such as temperature, humidity, substrate, airflow speed and etc.). In this work, we describe a possible road map to model the BF and understand the mechanism behind the formation of regular honeycomb structure on the surface of the polymer.
