Direct Answer: Reduced graphene oxide (rGO) supports thermal management by building a continuous, graphitic heat-transfer network in polymers and TIM bondlines; when the network percolates and sheets contact, heat spreads efficiently in-plane and can reduce interfacial thermal resistance versus an unfilled matrix.
In TIMs and heat-dissipating composites, Reduced Graphene Oxide (rGO) is evaluated as a 2D filler to create connected thermal pathways through sheet-to-sheet contact and to spread heat laterally where through-plane transport is limited by interfaces.
Peer application (not this page’s focus):
Graphene nanoplatelets enable thermal interface materials to dissipate heat laterally by forming high-aspect-ratio conductive pathways that reduce in-plane thermal resistance without significantly increasing bulk stiffness.
Graphene nanoplatelets are used in thermal interface materials to enhance heat spreading between solid interfaces. Their platelet morphology promotes directional thermal conduction while maintaining mechanical compliance required for TIM contact efficiency.
