“…This processing, often done far from equilibrium, is necessary to generate the desirable features afforded by nanostructured polymer materials (e.g., high porosity, well-defined pore structures) within membrane form factors. Yong Wang from the State Key Laboratory of Materials-Oriented Chemical Engineering reports the fabrication of hollow fiber membranes from polysulfone- block -poly(ethylene glycol) (PSF- b -PEG) materials. The PSF- b -PEG materials are melt-spun into hollow fibers that are then stretched axially.…”
