Paper on new method of patterning microporous membrane is published!

Check out our newly published paper on patterning microporous PVDF membrane using thermally induced phase separation (TIPS process).  When TIPS process is confined within a patterned soft mold (made of PDMS), the features on the molds are replicated onto the PVDF membrane after solvent extraction.  The patterning fadelity is between 0.5-0.7, comparable with exsiting methods of phase inversion micromolding, and nanoimprint lithography (which our group developed).  The as-patterned membrane has more symmetric pore structures, compared with the ones made from phase inversion.  Such properties could be beneficial for separation processes like membrane distillation (MD).
