Directional freezing of liquid crystalline systems: From silver nanowire/PVA aqueous dispersions to highly ordered and electrically conductive macroporous scaffolds
Highly ordered hybrid metallic-polymeric assemblies were prepared by simultaneously combining two organization-directing tools: the liquid crystalline behavior of high aspect ratio silver nanowires (Ag-NWs) dispersed in poly(vinyl alcohol) (PVA) aqueous solutions and a cryogenic technique based on t...
