The miscibility of carboxymethyl chitosan/polyethylenimine (CMCS/PEI) blends was analyzed by FT-IR, TGA and SEM. Defect-free CMCS/PEI blend membranes were prepared with polysulfone (PSf) ultrafiltration membranes as support layer for the separation of CO(2)/N(2) mixtures. The results demonstrate that the CMCS/PEI blend is miscible, due to the hydrogen(More)
