Highly stretchable, transparent and scalable elastomers with tunable dielectric permittivity

Abstract

We report a fast and simple process for the large scale fabrication of highly flexible, optically transparent carbon nanotube composites with massive dielectric permittivity. Various concentrations of pristine SWNTs were dispersed in hyperbranched polyurethane to prepare uniformly dispersed nanocomposite materials. Our solution-based method does not require modification on the carbon nanotubes, thus preserving the intrinsic electronic and high mechanical properties of the composites.
