▎ 摘　　要

NOVELTY - A membrane comprises a polymeric porous hollow fiber substrate and a coating comprising graphene oxide and amine, arranged on the surface of the polymeric porous hollow fiber substrate (114). USE - Membrane for carbon dioxide capture from flue gas exhaust in coal-fired power generation plant and for carbon dioxide separation from natural gas or biogas. ADVANTAGE - The membrane is feasible and economically viable for carbon dioxide capture. The membrane serves as an effective carbon dioxide carrier and greatly enhances carbon dioxide solubility and transport rate, especially under wet conditions and at elevated temperatures. The presence of water in the membrane can result in higher carbon dioxide permeance than that of other gases and increases the selectivity of carbon dioxide over other gases. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) removing carbon dioxide from a mixture of gas; and (2) forming a coated polymeric hollow fiber support which involves dispersing graphene oxide and amine in a coating solution comprising a solvent and exposing a polymeric hollow fiber support having carbon dioxide/nitrogen selectivity of 200-2000 and carbon dioxide permeance of 100-1000 gas permeation units to the coating solution. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a system for coating a graphene oxide membrane onto a hollow fiber substrate.
