The effect of the viscosity of polycarbonate (PC) matrix on the thermal conductivity of PC/vapor-grown carbon fiber (VGCF) composite was investigated in terms of the rheological properties of PC/VGCF. Thermal conductivity of low viscosity PC increased with contents of VGCF in spite of adding the same amount of VGCF. From the result of the rheological properties which were originated in the network structure, we clarified that the dense network of VGCF could be formed in lower viscosity matrix.
