Abstract

We present a controlling technique of microporous structure by laser irradiation during self-organization process. Polymer solution was dropped on the substrate at high humid condition and the honeycomb structure of regularly aligned pores on the film was fabricated by attaching of water droplets on the solution surface. We demonstrated that it was possible to prevent forming of pores at the region of laser irradiation and flat surface was fabricated. The method of our study is microfabrication processing technique that combines the advantages of bottom up and top down techniques. This method is expected that it is applied to photonic crystals, biological cell culturing, surface science and electronics fields.
