Thermal properties of graphene/me preview & related …
However, the graphene/metal composites possessing both high thermal conductivity (TC) and low coefficient of thermal expansion (CTE) have not yet been realized. Herein, we reported an efficient strategy to achieve a high alignment of graphene nanosheets (GNSs) in GNS/Cu composites through a vacuum filtration method followed by spark plasma sintering.

Petroleum coke - Wikipedia
Petroleum coke, abbreviated coke or petcoke, is a final carbon-rich solid material that derives from oil refining, and is one type of the group of fuels referred to as cokes.Petcoke is the coke that, in particular, derives from a final cracking process—a thermo-based chemical engineering process that splits long chain hydrocarbons of petroleum into shorter chains—that takes place in units

A useful first approach is to think in terms of maintaining a sufficiently high electrical conductivity while striving for a low thermal conductivity as possible. This may be feasible due to the fact that phonons possess a certain mean free path and structural units such as grains and precipitates in this range may constrain the propagation of phonons resulting in a significantly reduced
