1. A multi-layer device including a light-transmissive electrode layer and a functional layer, the light-transmissive electrode layer comprising a dry porous mesh, the dry porous mesh comprising carbon nanotubes or carbon nanowires, and a cross-linked polysaccharide formed by a reaction of a cross-linkable polysaccharide and a cross-linking agent that is a salt of a divalent or trivalent metal,
wherein the light-transmissive electrode layer transmits 60 percent or more of incident visible light such that images and colors present in an underlying layer of the multi-layer device, are visible to an observer looking through the light-transmissive electrode layer, and
wherein the functional layer is an electro-optic material layer comprising a binder and an electrophoretic medium encapsulated in microcapsules, or
wherein the functional layer comprises liquid crystals, or
wherein the multi-layer device is a flexible organic electro-optic device or light emitting diode, and the functional layer comprises a component selected from the group consisting of an insulator, a capacitor, a resistor, an n-type transistor, a p-type transistor, a polymer, a small molecule, and combinations thereof, that can transport electrons or holes.
