▎ 摘　　要

NOVELTY - A zinc ion functionalized graphene filled hybrid film comprises 97.5-99.5 mass% polyether block amide copolymer and 34.2 mass% zinc ion functionalized graphene, where thickness of the hybrid film is 85-100 mu m. USE - Zinc ion functionalized graphene filled hybrid film for separating carbon dioxide/methane (claimed). ADVANTAGE - The hybrid film is prepared with better mechanical and long-term process stability and better separating performance of carbon dioxide in dry environment in a simple manner. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for the following: (1) a method for preparing zinc ion functionalized graphene filled hybrid film (2) an application for zinc ion functionalized graphene filled hybrid film.
