Fabrication and Characterization of Graphene/polyimide Composite Film

A flexible graphene and polyimide composite film was designed and fabricated in this study. A polyimide solution was used as an adhesive layer to connect graphene film and polyimide film by hot-pressing. Laser flash thermal analysis method was carried out to evaluate the thermal diffusion coefficient of different thicknesses of the fabricated films at various temperatures. Bending test was carried...
