Nonadiamond (ND) are renowned as superlative material due to their relatively high thermal conductivity and hardness while comparing with any bulk materials. In the paper, the polyacrylonitrile/nanonodiamond (PAN/ND) precursors were fabricated via electrospinning using the PAN solution incorporated with ND at an alteration of mass fractions. The C/ND nanofibers were preparation from the carbonization of PAN/ND precursors. And then, composite nanofibers are characterized by scanning electron microscope (SEM), fourier transform infrared spectroscopy (FTIR), and so on. The results show that the thermal conductivity of the C/ND nanofiber composite nanofibers with 50 wt% ND incorporation reached 6.7 W/(m•k), which is about 2.7 times that of the C/ND composite nanofiber without ND.
