Abstract
Improved coextruded ribbons of material, such as can be used for making relatively fine conductive or ceramic lines or structures, having relatively high aspect ratios, are provided. The inks used to form the coextruded structures lack a yield stress and a high viscosity, but react at their interface to form a material having a finite yield stress or a high viscosity. This material then supports the shape of the extruded ink such that structures can be formed therefrom.
