Microgel-functionalized membranes — •Matthias Wessling — DWI Leibniz Institute for Interactive Materials, Aachen, Germany

Microgels are interactive soft colloids that can be triggered and tuned. They change size, charge, and density. This presentation explores the use of microgels to functionalize synthetic membranes. Examples will demonstrate that (a) temperature modulation tunes size exclusion (b) charge control influences electro-static repulsion of charged organic dye molecules while passing uncharged molecules of an even larger size (c) monolayers of microgels tune the monovalent/bivalent ion selectivity of synthetic ion exchange membranes (d) printed dotlike patterns of microgel monolayers effectively actuate chaotic electro-convection at polarized ion exchange membrane.
