The formation of polymeric honeycomb structure in the presence of different organic liquids — Farid Farajollahi, Masoud Amirkhani, and •Othmar Marti — Institute of Experimental Physics, Ulm University, Albert-Einstein-Allee 11, 89081 Ulm, Germany

Micro porous polymer structures have several applications in photonic devices, cell culturing scaffolds and super hydrophobic surfaces. Recently, self assembly of polymers into micro structures have gained more attention and different methods have been suggested for fabrication desirable patterns. Condensation of water on a volatile polymeric solution which called Breath Figure is one of the new method to produce order micro structure. The ability to make order bubble pattern with one step precess have provided unique properties for breath figure method.

In this research, we made the micro bubble structure by adding a small amount of different organic liquid to linear polystyrene solution. By adjusting the concentration of organic liquid, the shape and structure of honeycomb pores can be tuned. For different organic liquid, the effect of length of carbon chain on the self assembled pattern have been investigated
