Fabrication and characterization of PEI/PVP-based carbon hollow fiber membranes for Co2/Ch4 and Co2/N2 separation

Carbon hollow fiber membranes derived from polymer blend of polyetherimide and polyvinylpyrrolidone (PVP) were extensively prepared through stabilization under air atmosphere followed by carbonization under N2 atmosphere. The effects of the PVP compositions on the thermal behavior, structure, and ga...
