The Importance of Heat Dissipation In Electronics

With the gradual development of electronic device products to the field of high integration and high computing, heat dissipation has become a problem to be solved in the production of electronic equipment. Metal materials have shortcomings such as high density, energy consumption, easy deformation, being difficult to recycle and to process. There is almost no room for price reduction. Graphene has good thermal conductivity and can be used as an excellent heat dissipation material for various electronic devices.

Accelerate Research and Practice of Graphene in Heat Dissipation

The excellent thermal properties and flexibility of graphene have prompted extensive research into its derivatives. Materials used for thermal management applications include graphene oxide, graphene films, graphene fibers, graphene foams, graphene laminates and etc. A mixture of liquid phase exfoliated (LPE) graphene and few-layer graphene flakes perform excellently as fillers in thermal pastes and thermal phase change materials. Meter-sized graphene films fabricated from exfoliated graphene flakes also show great potential as heat spreaders.

Another promising 2D material for thermal management is boron nitride (BN), which has similar lattice to graphene. Moreover, BN is an electrical-insulating material which makes it a strategically important and very good complementary to graphene and their derivatives where electrical conduction is not allowed.
