Graphene foam (GF), carbon fibers (CFs) and GF/CFs reinforced epoxy resin composites were fabricated and their thermal properties were investigated. Due to continuous interconnected structures of GF and avoiding the CFs aggregation in epoxy resin, GF/CFs reinforced epoxy resin demonstrates greatly higher thermal conductivity than the single GF or CFs reinforced epoxy, which could provide a strong...
In this contribution, for the first time, the effect of crosslink degree on the thermal conductivity of silicone-based thermal conductive materials has been experimentally investigated. Hyper-branched silicone bases with different branching degrees and cross-linkable functional group densities are designed and synthesized via a one-pot, simple and efficient route. The resulting silicone bases can...

Amorphous carbon sphere precursor with low thermal conductivity was first prepared by hydrothermal reaction of glucose. After treatment with KOH and Fe(NO3)3 at high temperature, highly porous and graphitic carbon spheres was obtained. The absorption of paraffin wax increases as the porosity increases, and the thermal conductivity of carbon increases with the graphitic degree. The graphitic degree...
Ag surface modified carbon nanotubes (CNT) were prepared by electro-less plating method. The thermal interface materials (TIM) were obtained by mixed epoxy and nanotubes. The conductivity of expoxy-Ag coated CNT was much higher than that of epoxy-CNT. The Ag modified CNT is a promising high thermal conductive filler for polymer-based TIM.
Thermal grease have numerous commercial and industrial applications in microelectronics, circuit board, heat exchangers, machniery, and appliances. A high loading of thermally conductive filler is essential to aquire a significant increase of thermal conductivity. In this paper, the alkyl silicone oil as a wetting agent was introduced into thermal grease in order to improve the filler loading. The...
With more and more high power high brightness LEDs adopted in general lighting applications, the state-of-the-art packages cannot meet the requirement of thermal management. Over-heating of an LED will cause premature failure because the efficiency, the spectrum, the reliability and the life of solid state lighting devices strongly depend on successful thermal management. Therefore, the requirement...
