P84 polyimide membranes with thicknesses ranging from 6 to 310 lm were successfully fabricated by spin coating. The glass transition temperature of the P84 powder was found to be 315 C using differential scanning calorimetry, whereas its decomposition temperature was 536 C using thermogravimetric an
## Abstract A series of blend membranes of poly(phenyl sulfone) (PPSU) with poly(bisphenol Aβ__co__β4βnitrophthalic anhydrideβ__co__β1,3βphenylenediamine) (PBNPI) were prepared through a solution casting method. This was done to examine the permeation characteristics of oxygen and nitrogen. The eff
