Title:
METAL-ORGANIC FRAMEWORK MATERIAL SEPARATION MEMBRANE, PREPARATION METHOD THEREFOR, AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2022/077562
Kind Code:
A1
Abstract:
Provided are a metal-organic framework material separation membrane and a method for preparing a metal-organic framework material separation membrane. The metal-organic framework material separation membrane comprises a base membrane and a metal-organic framework material functional layer, and the structure of the metal-organic framework material functional layer comprises an inter-embedded polyhedral structure. The preparation method for the metal-organic framework material separation membrane comprises: (1) preparing a solution containing a first organic solvent, an organic ligand, a metal compound and an auxiliary agent; (2) subjecting a base membrane to a pretreatment, involving introducing, on the surface of the base membrane, metal atoms from the metal compound of step (1); and (3) mixing the pretreated base membrane of step (2) with the solution of step (1) to obtain a first mixture, and then heating the first mixture for a reaction, so as to prepare a metal-organic framework material separation membrane. An organic gas separation membrane prepared from the present invention has the properties of a high separation coefficient, a large flux, adhesion resistance, pollution resistance, etc. during an application process.
