Applying breath figure technique for the fabrication of porous film using various solvents — •mandeep singh, farid farajollahi, othmar marti, and masoud amirkhani — Institute of Experimental Physics, University of Ulm, 89069 Ulm, Germany

Elsewhere, has been shown that using the breath figure technique and adding the appropriate amount of alcohol to the solution of polymer/chloroform one can fabricate a well order honeycomb structure on the surface of polymer film. In this study, we show how different solvent may effect on the structure and size of pores on the surface. We employed several organic solvent from different solvent family and with various evaporation rates while the polymer (polystyrene) and alcohol (methanol) remain same for all samples. This study enables us to formulate underling important parameter, which governs the formation of porous structure.
