1. A hybrid thermal management film for electronic devices that has thermal conductivity and electrical insulation, comprising:
graphene fluoride nanosheets (GFS); and
reduced graphene oxide (rGO);
wherein the rGO and GFS are aligned in an in-plane direction of the hybrid thermal management film and the rGO forms a network through connection with the GFS,
wherein the network through connection provides a directly thermally conductive path for thermal conduction along the in-plane direction, and
wherein the rGO is included in an amount of 5 wt % to 20 wt % based on a total weight of the hybrid thermal management film.
