Non-activation ZnO array as a buffering layer to fabricate strongly adhesive metal–organic framework/PVDF hollow fiber membranes
A non-activation (NA) ZnO array is directly grown on a PVDF hollow fiber membrane. The defect-free MOF layers can be synthesized easily on the NA-ZnO array without any activation procedure. The array and MOF layers are strongly adhered to the hollow fiber membrane. The prepared ZIF membranes exhibit excellent gas separation performances.
