The anisotropic thermally conductive flexible films with nanofibrillated cellulose (NFC) and in situ reduced graphene oxide (RGO) nanosheets are prepared via a vacuum-assisted self-assembly technique. The hybrid films exhibit superior in-plane thermal conductivities, and a value of 6.168 W m(-1) K-1 is achieved with 30 wt% GO loading. Noteworthily, the through-plane thermal conductivities are extremely low (
