▎ 摘  要

NOVELTY - A block polyether amide-aminated graphene oxide hybrid film comprises block polyether amide and aminated graphene oxide, where the aminated graphite oxide comprises graphene oxide and 3-aminopropyltriethoxysilane formed under amination reaction in a catalysis condition. USE - Block polyether amide-aminated graphene oxide hybrid film for separating carbon dioxide/methane and carbon dioxide/nitrogen gas (claimed). ADVANTAGE - The hybrid film has improved breaking strength, and can be prepared in simple, controllable and easy manner. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing a block polyether amide-aminated graphene oxide hybrid film.
