Synthesis and characterizations of graphene-based composite film for thermal dissipation

In this study, we develop a series of graphene nanosheets(GNs)/carbon nanotubes(CNTs)/copper(Cu) composite film for heat dissipation. Scanning electronic microscopy (SEM), Raman spectroscopy, X-ray photo spectroscopy (XPS), Laser flash and infrared thermal images of composite film are carried out in this study. We discovered that the content of CNTs in composite film plays an important role on heat dissipation performance. Optimized ratio of GNs...
