Fluororesin thin film, fluororesin composite and production method thereof, porous fluororesin composite, and separation membrane element

摘要

A fluororesin powder is formed on a fluororesin thin film that has no defects such as voids and cracks and is made of a fluororesin, and has a film thickness of 20 μm or less and a Gurley second of 300 seconds or more. A method for producing the fluororesin thin film, the fluororesin dispersion, and a porous material, wherein the fluororesin dispersion dispersed in the dispersion medium is applied, and then the dispersion medium is dried and the fluororesin powder is sintered. A fluororesin composite having a body substrate and the fluororesin thin film, a method for producing the same, a porous fluororesin composite formed by stretching the fluororesin composite, and a separation using the porous fluororesin composite Membrane element.
