 The ordered honeycomb-patterned polyether sulfone (PES) porous membranes were fabricated by the “Breath figures” (BFs) method, microstructure of the membranes were characterized by SEM。The microstructure of membrane surface and the size of the pore can be controlled by concentration, and humidity and so on. The experimental results show that high humidity and proper polymer concentration are essential to fabricate honeycomb patterned films. The key role of forming honeycomb pattern is evaporation of solvent. When the solvent, humidity, concentration, injection are CH2Cl2 , 93.5% RH,2 wt %,60μL respectively, honeycomb pattern will be the best.
