Title:
CONDUCTIVE MEMBRANE AND PREPARATION METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2021/102860
Kind Code:
A1
Abstract:
Disclosed is a conductive membrane and a preparation method thereof, belonging to the technical field of membrane separation. The conductive membrane provided in the present application comprises a porous base membrane layer, a porous intermediate transitional membrane layer, and a porous conductive membrane layer stacked in sequence. At least some pores in the base membrane layer are connected to the pores of the conductive membrane layer via the pores of the intermediate transitional membrane layer. The base membrane layer, the intermediate transitional membrane layer and the conductive membrane layer are made of the same material. The conductive membrane provided in the present application can be combined with electrochemical technology, and exhibits novel and excellent performance while achieving a separation function. The configuration of the three-layer porous membrane structure enables the conductive membrane provided in the present application to reduce membrane resistance and obtain a high retention efficiency as well as a high solution penetration under low-pressure driving, reducing energy consumption. The conductive membrane can be combined with electrochemical technology, improving the separation function of the membrane and reducing membrane pollution, and reducing material consumption.
