▎ 摘　　要

NOVELTY - The membrane has a fibrous porous support layer having a surface that is coated with a separation functional layer, a particle layer interposed partially between the porous support layer and the separation functional layer. The particle layer comprising fibers shaped grains and/or tabular grains. The flat particles are a cellulose nanofiber, a carbon nanohorn, a carbon nano ribbon, a carbon nanotube, a graphene, and kind selected from the group consisting of graphene. USE - Fluid separation membrane for separating components from gas and liquid. ADVANTAGE - The fluid separation membrane can be provided with high separation performance and long-term stability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for manufacturing the porous material.
