<P>PROBLEM TO BE SOLVED: To provide a production method for a film obtained by utilizing a self-organizing phenomenon, being composed of a hydrophobic polymer and a phospholipid and having uniformly arranged pores. <P>SOLUTION: The production method for the film composed of the hydrophobic polymer and the phospholipid and having uniformly arranged 0.1-100 μm pores, is carried out by the followings. After forming a liquid film by casting a solution containing 100 pts.wt. hydrophobic polymer, 0.1-100 pts.wt. phospholipid and a hydrophobic organic solvent onto a substrate under the reaction atmosphere at 10-30°C and of 1,000-10,000 ppm water concentration, gas with 3,000-15,000 ppm water concentration is allowed to flow on the liquid film at 10-150 mL/min.cm<SP>2</SP>flow rate. <P>COPYRIGHT: (C)2007,JPO&INPIT |
