FABRICATION METHOD OF POLYMER FILMS

摘要

According to an embodiment of the present invention, a fabrication method of a polymer film comprises: a first step for applying a PVDF-based polymer solution dissolved in a solvent onto a carrier film; a second step for volatilizing the solvent in the PVDF-based polymer solution applied on the carrier film and obtaining a PVDF-based polymer film; a third step for laminating a support film onto the dried PVDF-based polymer film; a forth step for immersing the PVDF-based polymer film in a liquid after lamination process; and a fifth step for detaching the PVDF-based polymer film and support film from the carrier film. Provided is a roll-to-roll type fabrication method of a polymer film which can produce a PVDF-based polymer film in a large quantity by controlling adhesive strength of the film.
