The invention belongs to membrane preparation technology field, relates generally to a kind of graphene oxide/Pebax hollow-fibre membranes and preparation method thereof.First counterdie is pre-processed water is full of into its counterdie micropore, then coated transition zone, separating layer on counterdie successively, produce the graphene oxide/Pebax hollow-fibre membranes, the counterdie is hollow-fibre membrane.The inventive method is simple to operate, creative that GO is applied into gas separation field, for CO 2 /N 2 Gaseous mixture has good centrifugation, and CO is greatly improved 2 Permeation flux, stable separation factor is maintained, as a kind of new gas separation membrane, be expected to obtain extensive use in actual industrial field. |
