Title:
CARBON MOLECULAR SIEVE MEMBRANE AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2021/109708
Kind Code:
A1
Abstract:
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.
