Abstract

A method for preparing a microporous layer. The method comprises the following steps: dissolving a nonionic surfactant and an alcohol solvent in water, so as to obtain a pre-prepared solution; uniformly dispersing carbon powder in the pre-prepared solution, so as to obtain a carbon powder dispersion liquid; uniformly dispersing an ionic polymer in which the main chain thereof is bonded to fluorine atoms into the carbon powder dispersion liquid, so as to obtain a microporous layer slurry; and disposing the microporous layer slurry on the surface of a microporous layer carrier to form a slurry layer, drying the slurry layer, and then roasting same at a predetermined temperature, so as to obtain a microporous layer. In the method, the ionic polymer containing fluorine atoms is used as a hydrophobic agent; the ionic polymer itself has hydrophilicity, can be dissolved in an aqueous ethanol solution, and thus can eliminate the phenomenon of demulsification; and the ionic polymer is uniformly dispersed in the microporous layer slurry, and is then roasted to remove hydrophilic side chains or side groups, so as to form hydrophobic macromolecules uniformly distributed in the microporous layer, thereby allowing the microporous layer to have relatively uniform hydrophobicity.
