Abstract
We investigated the effects of concentration in solution, humidity and difference in temperature between substrate and humid air on pore size. We fabricated porous polymer thin films by using the breath figure method. As the experimental results, a porous polymer thin film with small pores was fabricated in a low humid condition and in condition with small temperature difference between substrate and humid air. A porous polymer thin film with 100-150 nm pores was fabricated by controlling growth time of water droplet.
