ULTRA-THIN POLYMER FILM, AND POROUS ULTRA-THIN POLYMER FILM |
摘要 |
The present invention addresses the problem of providing a porous ultra-thin polymer film, and a production method for a porous ultra-thin polymer film. The present invention provides a porous ultra-thin polymer film having a film thickness of 10-1000 nm. The present invention also provides a production method for a porous ultra-thin polymer film, said method comprising: a step in which two incompatible polymers are dissolved in a first solvent at an arbitrarily-defined ratio to obtain a solution; a step in which the solution is applied to a substrate and the first solvent is eliminated from the solution applied to the substrate to obtain an ultra-thin polymer film in which the phases have separated into a sea-island structure; and a step in which the ultra-thin polymer film is immersed in a second solvent that is a good solvent for the polymer constituting the islands and a poor solvent for the polymer constituting the parts other than the islands in order to remove the islands and thereby obtain a porous ultra-thin polymer film. |
