  • Method for fabricating nanoporous polymer thin film and corresponding method for fabricating nanoporous thin film
    Patent number: 11059205
    Abstract: A method for fabricating nanoporous polymer thin film includes steps as follows. A polymer thin film is provided, wherein a polymer solution including a polymer is coated on a substrate to form the polymer thin film. A swelling and annealing process is provided, wherein the polymer thin film is disposed inside a chamber with a vapor of a first solvent, the polymer thin film is swollen and annealed to form a swollen polymer thin film, and the swollen polymer thin film includes the polymer and the first solvent. A freezing process is provided, wherein the swollen polymer thin film is cooled to a temperature less than or equal to a crystallization temperature of the first solvent to crystallize the first solvent. A first solvent removing process is provided, wherein the first solvent is removed with a second solvent, such that a nanoporous polymer thin film is obtained.
