From the author: A methodology for preparing porous polysulfone (PSF) monolith via concentrated emulsion templating was proposed. A regular emulsion was first prepared using a solution of PSF in chloroform as the continuous phase and deionized water as the dispersed one. After the emusion was formed, the liquid species in the emulsion was allowed to be evaporated. The solvent chloroform was first removed and the emulsion was transformed to a concentrated emulsion. Further removing the aqueous species, a porous PSF monolith was obtained. To keep the system stable throughout the process, an aminated polysulfone rather than conventional surfactants was employed. The effects of chloroform and water fractions, the nature and loading of the macromolecular surfactant, the evaporating temperature on the pore structure were investigated. Controlled porous structure with different pore size and porosity could be obtained through the method. POLYM. ENG. SCI., 51:1245-1252, 2011. [c] 2010 Society of Plastics Engineers
