Abstract

Abstract Four kinds of solvent were chosen to prepare poly(ether sulfones) (PES) filtration membranes by the nonsolvent induced phase separation (NIPS) method. Ternary phase diagram and shear viscosity measurement were conducted to analyse the formation of prepared membrane from thermodynamic and kinetic perspectives. The micro-structure of the membranes with different solvents were analysed, and the result showed a high relevance to the thermodynamics and dynamics of the casting solutions, and promoted the proposal of a reasonable membrane formation mechanism.
