Polymers with intrinsic micro porosity (PIMs) have recently received great attention due to their novel properties such as high surface area, adjustable pores, light weight and chemical stability. In general, micro porous polymers are constructed by crosslinked monomers and thus they don`t dissolve in common solvents. PIMs, on the other hand, can be dissolved in aprotic solvents and can be processed as gas separation membranes. However, PIM-casted membranes show poor mechanical properties as they suffer from highly brittle film formation. Here, we studied PIM based polymers and improved their mechanical properties by blending them with rubbery polymers. Resultant membranes showed improved film formation. In addition, gas transport properties of blended membranes were studied for potential use in post-combustion flue gas separation applications.
