Abstract

Heat dissipation coatings with high thermal conductivity play an important role in the thermal management of many industrial applications. It is still a big challenge to prepare highly thermal conductive coatings in the industry. Herein, we report a novel approach to prepare highly conductive thermal polyurethane composite coatings which contain dopamine-modified conductive fillers. Graphene oxide (GO), carbon nanotube (CNT), and nano-diamond (ND) were used as two-dimensional (2D), one-dimensional (1D), and zero-dimensional (0D) thermal conductive fillers respectively. The thermal conductivity test results indicate that GO and CNT can form a “bridge-like” structure and build more heat conduction channels. The test shows that the 2D + 1D combination has better thermal conductivity and more synergistic effect than the 2D + 0D combination.
