Carbon-based materials such as carbon nanotubes (CNTs) and graphene have attracted attention because of ultrahigh thermal conductivity by limited phonon scattering and high phonon velocity. For a broader range of applications of carbon-based materials, fabrication of freestanding thin film is one of important issue. We can fabricate freestanding rGO thin film with low-cost and large-scale production using vacuum filtration method. For many potential applications, basic properties of rGO thin film are very important. Mechanical properties and electrical conductivity of rGO thin film were reported. However, thermal conductivity properties of rGO thin film and rGO layer have not been reported yet.Herein, we report a freestanding rGO thin film by vacuum filtration method and its thermal conductivity by a self-heating 3? method.
