The prospect of electronic circuits that are stretchable and bendable promises tantalizing applications such as skin-like electronics, roll-up displays, conformable sensors and actuators, and lightweight solar cells. The preparation of highly conductive and highly extensible materials remains a challenge for mass production applications, such as free-standing films or printable composite inks. Here we present a nanocomposite material consisting of carbon nanotubes, ionic liquid, silver nanoparticles, and polystyrene- polyisoprene-polystyrene having a high electrical conductivity of 3700 S cm -1 that can be stretched to 288% without permanent damage. The material is prepared as a concentrated dispersion suitable for simple processing into …
