Title:
NANOFIBER/MOFS-BASED PREFERENTIAL ALCOHOL-PERMEABLE PERVAPORATION MEMBRANE AND PREPARATION METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2022/121594
Kind Code:
A1
Abstract:
The present invention relates to the technical field of membrane separation, and discloses a method for preparing a nanofiber/MOFs-based preferential alcohol-permeable pervaporation membrane. The present invention first provides the strategy of uniformly pre-loading MOFs particles onto a porous fiber gel matrix and using said particles as a "composite network filler" of a pervaporation membrane, and then backfilling with a polymer base and curing, such that uniform dispersion of high-load MOFs particles in the polymer base can be effectively achieved, and the obtained mixed matrix membrane has excellent mechanical properties, high-efficiency permeation and vaporization performance, and good application prospects in the aspect of separation of mixed systems of bio-alcohols such as ethanol and butanol.
