A broad area of researches has been dedicated to develop MMMs for CO2 separation. MMMs are normally comprised of different kinds of fillers embedded into the polymer matrices with a final goal of surpassing the Robeson's upper boundary not only by controlling shortcomings of the available organic and inorganic membrane materials, but also through a fast upgrading of them. One of the most important aspects in the development of MMMs is an appropriate material selection for both matrix and dispersed phases to eliminate the non-ideal morphologies created at their interfaces. Development of high performance membrane materials with new functional groups and new chemistries has attracted much attention over the past few years. To have an impact on real implementations, successful MMMs are necessary to optimize multiple functions besides high porous structure and surface area, such as processability, stability, sorption kinetics, mechanical and thermal properties, while simultaneously the economic issues must be taking ...
