WIPO Patent Application WO/2021/233184
Kind Code:
A1
Abstract:
A fluid separation membrane, and a manufacturing method therefor and the use thereof. The fluid separation membrane comprises: a separation function membrane layer (1), wherein the separation function membrane layer (1) comprises a single function membrane layer (11) and/or a combined function membrane layer (12); a lower surface of the separation function membrane layer (1) is provided with a first support layer (2), and the first support layer (2) comprises a single support layer or a multi-layer combined support layer; an upper surface of the separation function membrane layer (1) is provided with a second support layer (3), and a symmetrical double-sided support layer structure is formed; and the second support layer (3) comprises a single support layer and/or a multi-layer combined support layer. The separation function membrane layer is a membrane layer made of a battery-separator-type material, wherein the battery separator material comprises a natural high polymer material, a synthetic high polymer material and an inorganic material; and the battery separator material comprises polypropylene (PP), polyethylene (PE) or polyimide (PI).
