Beschreibung
Zusammenfassung:	The invention discloses a graphene oxide/ZIF-8 composite diaphragm and a preparation method thereof.According to the graphene oxide/ZIF-8 composite diaphragm, a thermal crosslinking polyvinyl alcohol/polyacrylic acid nanofiber membrane serves as a base membrane, ZIF-8 nanoparticles with positive charges and graphene oxide with negative charges are sequentially assembled to the base membrane through the soaking layer-by-layer self-assembly technology, and the graphene oxide/ZIF-8 composite diaphragm is obtained. The graphene oxide/ZIF-8 modified layer is formed until the required number of layers of the graphene oxide/ZIF-8 modified layer is reached, and the graphene oxide/ZIF-8 composite diaphragm can be prepared. The graphene oxide/ZIF-8 composite diaphragm can be used as a lithium-sulfur battery diaphragm material or a lithium ion battery diaphragm material, has good mechanical properties, chemical stability and the like, and can effectively inhibit the shuttle effect of polysulfide when being used as the l
