Fabrication of polymer based on self-organization and its application

Research output: Chapter in Book/Report/Conference proceedingConference contribution


We describe the fabrication and characterization of highly regular porous surfaces formed by a solution casting (bottom up) technique under humid air condition. Condensation of water from the air due to evaporation cooling was occurred when water-immissible solvent was used. Self-packed and mono-dispersed water droplets formed on the solution surface act as a temporary template of pores. Various experimental factors affecting the pore and pillar structures were studied. The porous surface shows a highly regular hexagonal arrangement of holes in a large area and can be easily peeled off from a substrate as a self-supported film. The pore size can be controlled in the range from 100 nm to 50 μm by changing the casting conditions. Unlike other templated or lithographic (top down) methods, advantage of this method is ease with which such patterned surfaces can be created using various materials. The 3-D patterned surfaces have a strong influence on the cell attachment and functions. The films with well-ordered nanostructure are applicable for biomedical-, photonic- and electronic materials.
