Kinetics of Thermal Degradation of Polysulfone/Polyimide Blended Polymeric Membranes

Flat-sheet asymmetric polysulfone (PSF)/ polyimide (PI) blended membranes were fabricated by a phase-inversion technique. The fabricated membranes were characterized by Fourier transform infrared spectroscopy, differential scanning calorimetry, and field emission scanning electron microscopy an...
