Thin and conductive plastic foils are of great interest to the target preparation and nuclear physics communities as backing support for neutron-induced reaction measurements. This paper describes the preparation and characterization of thin, freestanding conductive polyimide films with an areal density suitable for target preparation in nuclear chemistry. The films were fabricated via blending a variety of graphene-based nanoparticles, a custom-made graphene suspension and carbon nanotubes with polymer matrix. The fabrication of freestanding polyimide films with areal density of 30 μg/cm2 (~210nm) is time-consuming and difficult. Here we describe a novel approach using a sacrificial layer and graphene material to make thin (pure and conductive) polyimide foils readily available within 24 hours.
