Title:
METHOD FOR PREPARING AROMATIC POLYAMIDE POROUS FILM AND AROMATIC POLYAMIDE POROUS FILM
Document Type and Number:
WIPO Patent Application WO/2017/133375
Kind Code:
A1
Abstract:
Provided are a method for preparing an aromatic polyamide porous film and an aromatic polyamide porous film. The preparation method comprises formulating an ionic liquid and an aromatic polyamide into a mixed solution by a solvent; and preparing the mixed solution in a sol bath into a film, and then extracting the solvent and the ionic liquid from the film via an extraction agent, so as to form the porous film. The present method uses an ionic liquid and reduces the use of additives; and the ionic liquid is high in stability, is easy to separate from other solvents and can be reused.
