The fabricated membranes were characterized by Fourier transform infrared spectroscopy, differential scanning calorimetry, and field emission scanning electron microscopy analyses. The kinetics of thermal degradation of the membranes were studied from thermogravimetric data following Friedman's kinetic approach. The thermal degradation process of the membranes followed first-order rate kinetics, and the activation energy of the thermal degradation process increased with increasing PI content of the membrane compositions. {\^A}{\copyright} 2011 Wiley Periodicals, Inc.}, keywords = {Blended membrane; blends; Field emission scanning electron microscopy; First-order rates; Kinetic approach; Membrane composition; Phase inversion; Thermal degradations; thermogravimetric analysis (TGA), Activation energy; Degradation; Differential scanning calorimetry; Field emission microscopes; Fourier transform infrared spectroscopy; Kinetics; Membranes; Polyimides; Polymeric membranes; Scanning electron microscopy, Thermogravimetric analysis}, url = {https://www.scopus.com/inward/record.uri?eid=2-s2.0-82955249194&doi=10.1002\%2fapp.34862&partnerID=40&md5=d172adfffd1394acb15eacd6114de864}, issn = {00218995}, author = {Rafiq, S. and Man, Z. and Maitra, S. and Muhammad, N. and Ahmad, F.} }
