The Preparation of Coal based Graphene and It’s Application in the Field of Thermal Conductivity

Graphene is a new material with good physical properties and high added value. Coal can be made into model compounds by different physical and chemical methods to realize the efficient utilization of coal, so that new coal based materials with high added value can be formed. Based on this, in the process of research and analysis, the preparation of coal based graphene and its application in the field of thermal conductivity were studied. Based on the lateral guiding excitation of graphene, its performance and application of thermal conductivity are analyzed comprehensively. On the basis of external force control, it has a positive effect on improving the thermal conductivity of graphene composites.
