The mechanical strength of polymeric membranes is one of the limitations for their applications. Carbon materials are effective in reinforcing polymeric materials, but it is unknown whether they would degrade the membranes’ gas separation performance. In this paper, using brominated poly (2,6-dimethyl-1,4-phenylene oxide) (BPPO) as matrix, nanocomposite membranes of BPPO/graphene, BPPO/carbon back and BPPO/fullerene were prepared. The CO2 permeability and CO2/N2 selectivity of the nanocomposite membranes were studied. Different from the BPPO/carbon black and BPPO/fullerene membranes, the BPPO/graphene membrane was found having improved gas separation performance after incorporation 2 wt. % graphene.
