A new, lightweight composite material for energy storage in flexible electronics, electric vehicles and aerospace applications has been experimentally shown to store energy at operating temperatures well above current commercial polymers, according to a team of Penn State scientists. This polymer-based, ultrathin material can be produced using techniques already used in industry.

This is the first robust experiment in which a soft polymeric material and a hard 2D crystalline material have come together to create a functional dielectric device. Combining the 2D materials with polymeric materials solves many of the inssues associated with scalling 2D crystaline materials to commercial production and is a key feature for future flexible electronics applications and electronic devices.
