Title
(EN) METHOD FOR PREPARING POROUS FLUOROPOLYMER FILMS
(FR) PROCEDE DE PREPARATION DE FILMS DE POLYMERE FLUORE POREUX
Abstract
(EN)
The invention relates to a method for preparing a porous film of a fluoropolymer, comprising the following steps: - providing an ink comprising the fluoropolymer and a vehicle comprising a solvent of the fluoropolymer and a non-solvent of the fluoropolymer, said solvent of the fluoropolymer and said non-solvent of the fluoropolymer being miscible with one another; - depositing the ink on a substrate; - evaporating the vehicle comprising the solvent and the non-solvent.
