Nanographene modification is used in transformer inductors, heat dissipation of electronic components, special cables, electronic packaging, heat conduction potting and other fields due to its good processing performance, low price and excellent thermal conductivity. Let's analyze the development prospect of nanographene modification!
Traditional thermally conductive plastics are mainly filled with polymer matrix materials with highly thermally conductive metal or inorganic filler particles. When the amount of filler reaches a degree, the filler forms a chain-like and network-like morphology in the system, that is, a thermally conductive network chain is formed. When the orientation direction of these thermally conductive mesh chains is parallel to the direction of heat flow, the thermal conductivity of the system will be greatly improved.
Graphene as a filler with high thermal conductivity plastic can meet the requirements of thermal management, high density and high integration in the electronics industry.
Compared with the melt blending method, the solution mixing method can better disperse graphene in the polymer matrix. This method has been widely used because of its good dispersion effect, fast preparation speed, and good control of the state of each component. However, this method requires the use of organic solvents, which will adversely affect the environment.
In the modification of nanographene, with the increase of the amount of graphene added, a thermal conductive network chain is gradually formed in the system, which greatly improves the thermal conductivity of the composite material. Due to the agglomeration of multi-layer graphene over time, its thermal conductivity will decrease. At the same time, the defects in graphene, the disorder of the edges, etc. will reduce the thermal conductivity of graphene.
