Abstract
An article of manufacture includes a substrate and a stretchable, conductive film. The stretchable, conductive film includes a plurality of annealed silver nanoparticles disposed on the substrate. The conductive film can be formed from a liquid composition comprising silver nanoparticles in a decalin solvent. The conductive film can further include a first conductivity associated with an as-annealed shape of the conductive film, and the film can include a second conductivity upon being stretched in at least one direction beyond the as-annealed shape.
