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.

Globally, environmental challenges have been recognised as a matter of concern. Among these challenges are the reduced availability and quality of drinking water, and greenhouse gases that give rise to change in climate by entrapping heat, which result in respirational illness from smog and air pollution. Globally, the rate of demand for the use of freshwater has outgrown the rate of population increase; as the rapid growth in town and cities place a huge pressure on neighbouring water resources. Besides, the rapid growth in anthropogenic activities, such as the generation of energy and its conveyance, release carbon dioxide and other greenhouse gases, warming the planet. Polymer nanocomposite has played a significant role in finding solutions to current environmental problems. It has found interest due to its high potential for the reduction of gas emission, and elimination of pollutants, heavy metals, dyes, and oil in wastewater. The revolution of integrating developed novel nanomaterials such as nanoparticles, carbon nanotubes, nanofibers and activated carbon, in polymers, have instigated revitalizing and favourable inventive nanotechnologies for the treatment of wastewater and gas separation. This review discusses the effective employment of polymer nanocomposites for environmental utilizations. Polymer nanocomposite membranes for wastewater treatment and gas separation were reviewed together with their mechanisms. The use of polymer nanocomposites as an adsorbent for toxic metals ions removal and an adsorbent for dye removal were also discussed, together with the mechanism of the adsorption process. Patents in the utilization of innovative polymeric nanocomposite membranes for environmental utilizations were discussed.
