Abstract
(EN)
Provided are a carbon molecular sieve membrane and a preparation method therefor. In the present invention, by subjecting a polyetherimide and a polymer with a similar structure to a series of treatments followed by controlled pyrolysis, a gas-separation carbon molecular sieve membrane which simultaneously has an increased pore volume and a reduced pore size and is rich in microporous structures is obtained.

L'invention concerne une membrane de tamis moléculaire en carbone et son procédé de préparation. Dans la présente invention, en soumettant un polyétherimide et un polymère ayant une structure similaire à une série de traitements suivis d'une pyrolyse contrôlée, on obtient une membrane de tamis moléculaire de carbone pour séparation de gaz qui a simultanément un volume de pore augmenté et une taille de pore réduite et est riche en structures microporeuses.
