Microstructured hollow fibers for ultrafiltration Çulfaz Emecen, Pınar Zeynep; Van Rijn, Cees; Lammertink, Rob G.H.; Wessling, Matthias (2010-02-01) Hollow fiber ultrafiltration membranes with a corrugated outer microstructure were prepared from a PES/PVP blend. The effect of spinning parameters such as air gap, take-up speed, polymer dope viscosity and coagulation value on the microstructure and membrane characteristics was investigated. Fibers with maximum 89% surface area enhancement were prepared. The structured fibers and the round fibers spun under the same conditions had comparable (intrinsic) pure water permeability, molecular weight cut-off, po...

Microporous patterned electrodes for color-matched electrochromic polymer displays Aubert, Pierre-Henri; ARGUN, Avni A.; Çırpan, Ali; TANNER, David B.; REYNOLDS, John R. (American Chemical Society (ACS), 2004-06-15) The emergence of electroactive and conducting polymers offers new opportunities for the design of materials for electrochromic devices (ECDs). Of these, poly(3,4-alkylenedioxythiophene)s (PXDOTs) and their derivatives exhibit the most promising electrochromic (EC) properties. Here, we report the use of highly porous metallized membranes which allow the production of patterned, rapid-switching, reflective ECDs. Using poly(3,4-ethylenedioxithiophene) (PEDOT), poly(3.,4-propylenedioxythiophene) (PProDOT), and ...
