Application of Hybrid Fillers for Improving the Through-Plane Heat Transport in Graphite Nanoplatelet-Based Thermal Interface Layers. [PDF]

open access: yes, 2015
The in-plane alignment of graphite nanoplatelets (GNPs) in thin thermal interface material (TIM) layers suppresses the though-plane heat transport thus limiting the performance of GNPs in the geometry normally required for thermal management applications.

FEATURES OF ULTRASONIC SPLITTING OF THERMALLY EXPANDED GRAPHITE

open access: yesIZVESTIYA VYSSHIKH UCHEBNYKH ZAVEDENII KHIMIYA KHIMICHESKAYA TEKHNOLOGIYA, 2020
Thermally expanded graphite is obtained from crucible graphite by treatment with oleum in the presence of an oxidizing agent.  The obtained samples of thermally expanded graphite were subjected to ultrasonic dispersion (splitting up) in four liquid media (water, toluene, benzene, acetone).
