A wide variety of commercial polymeric membranes are manufactured by a non-solvent immersion precipitation process, yet the detailed mechanism and kinetics of membrane formation are poorly understood. We have used a confocal microscope, with fluoresc

Poly(amic diethyl ester) [PAE] precursors of four different polyimides with various chain rigidities were synthesized and thermally converted to the polyimides in thin films: rodlike poly( p -phenylene pyromellitimide) [PMDA-PDA] and poly(4,4′-biph

The possibility of crossing the spinodal boundary by isothermal evaporation in a polymer-1/solvent/polymer-2 system is analyzed. It is found that when the relative diffusional velocity between polymers is zero, the ternary system may be treated as qu
