Pure versus mixed gas permeability of novel polymers of intrinsic microporosity

The level of CO2 in the atmosphere is rising due to a continuous consumption of fossil fuels for industrial and domestic use. This necessitates the development of new technologies to avoid a climate change, which would cause a risk for the life on our planet. Membrane separation processes are seen as one of the potential solutions to the problem, offering the advantage of cheap production and simplicity of operation compared to other separation techniques. One of the most ambitious projects to reduce CO2 emission is the capture of CO2 from CO2/N2 mixtures, like in flue gas. In the present study, materials with high intrinsic microporosity (PIMs) are studied and their performance in terms of CO2/N2 separation is evaluated.
