Abstract

Micron-thick hydrogel films with ordered 3D mesostructures form spontaneously at the interface of polyelectrolyte-surfactant solutions. Here we demonstrate that by rationally designing the micelle shapes it is possible to predict and so tailor the nanostructure formed within surfactant-polyelectrolyte films. Using quaternary ammonium surfactants with a range of packing parameters, we demonstrate that micelle shape in solution governs the ordered liquid crystalline phase found in the polymer-surfactant composite films. Such structural control allows modification of film properties to potentially enhance their effectiveness for applications such as inorganic templating, encapsulation and molecular sensing.
