Thermal reduced graphene oxide (TRG) was performed to obtain the TRG/polystyrene (TRG/PS) composite fibers by solution blending followed by electrospinning technique. And then the thermally conductive TRG/PS nanocomposites were fabricated via hot press method. The thermally conductive coefficient (lambda), thermal diffusion coefficient (alpha), glass transition temperature (T-g) and heat-resistance index (T-HRI) of the obtained TRG/PS nanocomposites were all improved with the increasing addition of TRG. The addition of 15 wt% TRG could increase the A. value of pure PS from 0.226 W/mK to 0.689 W/mK, a value from 0.2157 mm(2)/s to 0.6545 mm(2)/s, T-g value from 90.3 degrees C to 95.0 degrees C and THAI value from 184.2 degrees C to 194.3 degrees C.
