Title:
PREPARATION METHOD FOR ION-EXCHANGE MEMBRANE HAVING ORDERED IONIC CONDUCTION STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2020/010660
Kind Code:
A1
Abstract:
A preparation method for an ion-exchange membrane having an ordered ionic conduction structure, comprising: first, synthesizing a polymer A containing a metal ligand structure; and then individually formulating the polymer A, or the polymer A and a polymer B, the polymer A and a filler, or the polymer A, the polymer B, and the filler into the membrane preparation solution, fully dissolving same, and letting same stand for defoaming; pouring same into a culture dish, and forming a membrane by means of a solvent evaporation method, a spin coating method, a dip-coating method, a roll-to-roll silkscreen print method, or an inkjet method at conditions of a certain pressure, temperature, time, magnetic field intensity or electric field intensity; and after the membrane formation process ends, ionizing the membrane to obtain the ion-exchange membrane. When a magnetic field or an electric field is applied during membrane formation, the ionic conduction structure of the ion-exchange membrane can be orderly regulated, and a highly efficient and durable ion-exchange membrane having the ordered ionic conduction structure can be prepared.
