thermal properties of graphene

and The anisotropic thermal conductivity (TC) and coefficient of thermal expansion (CTE) of graphene/Cu composite is studied. Huang, Huaqing While, the insulation properties of epoxy composites were retained significantly in contrast to RGO/epoxy composites. Thermal interface materials (TIMs) are essential ingredients of thermal management and researchers have achieved a record enhancement of the thermal conductivity of TIMs by addition of an optimized mixture of graphene and multilayer graphene ("Graphene sets new record as the most efficient filler for thermal interface materials"). Lee, Churl Seung Tayari, V. Li, Ran Composites of graphene and matrix materials are expected to be the most promising TIMs because of the remarkable thermal conductivity of graphene. Ryndyk, D. A.

Graphene is a two-dimensional (2D) material with over 100-fold anisotropy of heat flow between the in-plane and out-of-plane directions. and Xu, Yong and Zhang, Jingchao High in-plane thermal conductivity is due to covalent sp2bonding between carbon atoms, whereas out-of-plane heat flow is limited by weak van der Waals coupling. Pop, Eric Bashirzadeh, M. Schelling, Patrick K. Intriguingly, the composites showed a reversed anisotropic behavior between TC and CTE as a function of GNS fraction, in which the in-plane TC was substantially higher than through-plane TC, whereas oppositely the through-plane CTE displayed a larger drop than in-plane CTE. Cuniberti, G. Also, the storage modulus was improved by 4.6% compared to the pure epoxy. and 2013. Yasaei, P. It is found that the settling of the alumina nanoparticles on the graphene surface not only inhibits the electron transfer but also eliminates the agglomerations of graphene. Bae, M.-H. 2013. 2013.

Graphene holds great potential in metal matrix composites for thermal management due to its excellent thermal properties. Pöller, Sascha At 6:4, the thermal conductivity was enhanced by 23.4%. and Graphene is, basically, a single atomic layer of graphite; an abundant mineral which is an allotrope of carbon that is made up of very tightly bonded carbon atoms organised into a hexagonal lattice. The composites showed a reversed anisotropic behavior between TC and CTE as a function of graphene fraction. Wang, Xinwei and and However, the graphene/metal composites possessing both high thermal conductivity (TC) and low coefficient of thermal expansion (CTE) have not yet been realized.
