Abstract: Graphene is the material with the highest thermal conductivity, it has a wide range of applications in the fields of energy storage, electronic devices, biological materials, sensing materials and catalyst carriers. However, few people have studied how to accurately measure the thermal conductivity of graphene films. Therefore, a method for measuring thermal conductivity of graphene films is proposed in this paper. The influence of different factors such as surface state, pulse width, sample thickness and measurement direction on the measurement accuracy of the graphene film are also analyzed. The results show that when the surface of the graphene film is sprayed with graphite, the measurement accuracy can be effectively improved. When the measurement technician chooses the appropriate pulse width, measurement thickness and measurement direction, the measurement accuracy of the graphene film can be effectively improved. The research produced data que will contribute to improve the measurement accuracy of graphene products and the level of operation of the technicians as well as contribute in the high-quality development of graphene industry.
