Carbon dioxide (CO2) makes up 78% of anthropogenic greenhouse gas production and has been linked to global climate change and ocean acidification. Therefore, as climate change becomes an increasingly unavoidable environmental, industrial, and political issue, it is desirable to develop technology capable of economically separating and sequestering large amounts of CO2. This separation and sequestration technology is also likely to play a role in maintaining the economic value of fossil fuels in the event of a concerted global CO2 mitigation effort. The initial step toward this technology is to identify and develop an economically viable method of separating CO2 from flue gas at large point sources such as coal-fired power plants. As an alternate CO2 capture technology, polymer-based membrane separations offer relatively low operating costs with low-maintenance requirements. Therefore, the development of highly selective and permeable membranes for the separation and ultimate sequestration of CO2 is of vital importance.
