▎ 摘　　要

NOVELTY - A hybrid film comprises dense separating layer and porous supporting layer and nano silver functionalized graphene nanosheets as filler, where the dense separating layer is polyether-polyamide block copolymer, which is utilized as matrix, mass ratio of filler and graphene is 2-8 mass%, the thickness of the separating layer is 0.5 mu m. the porous supporting layer is polysulfone ultrafiltration membrane having molecular weight cut off 20 kDa. USE - Hybrid film for oil desulfurization by pervaporation technique (claimed). ADVANTAGE - The hybrid film is prepared in a simple manner, and has higher separation performance. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for the following: (1) a method for preparing the hybrid film (2) a use of the hybrid film.
