▎ 摘　　要

NOVELTY - A carbon nanotube/graphene oxide based polyimide gas separation membrane is obtained by wrapping carbon nanotube, dispersing with dimethyl acetamide, adding polyimide, followed by dissolving and forming spin coating film to obtain finished product. USE - Carbon nanotube/graphene oxide based polyimide gas separation membrane. ADVANTAGE - The membrane has better thermal stability, high gas permeability and high separation factor.
