Thermal interface materials based on carbon nanotubes and their thermal characterization

The effects of using different fillers and the effects of filler content and particle size on the thermal properties of thermal interface materials were investigated. The most prominent enhancement in thermal conductivity was observed for samples containing carbon nanotubes and graphite. The filler particle size was also found to significantly affect the thermal conductivity, as smaller fillers resulted in a higher thermal conductivity. The article also describes two sample holders ...

Enhancement of physical properties of electroactive polyimide nanocomposites by addition of graphene nanosheets

The thermal imidization method was used to prepare an electroactive polyimide/graphene nanocomposite (EPGN) material membrane. It was determined that the composites that were formed had improved mechanical strength, thermal stability, and thermal conductivity, as well as an improved dielectric constant and a decreased gas permeability in comparison to electroactive polyimide membranes....

Thermal energy storage performance of paraffin-based composite phase change materials filled with hexagonal boron nitride nanosheets

A paraffin-based composite phase change material (PCM) was prepared by the addition of hexagonal boron nitride (h-BN) nanosheets to melted paraffin wax followed by vigorous stirring. The nanosheets were added in quantities ranging from 1 to 10 wt. %. A reference sample of pure paraffin was also prepared. It was determined that the addition of h-BN nanosheets resulted in an increase in thermal conductivity and that the melting and solidification rates were also ...

Graphite nanoplatelet/silicone composites for thermal interface applications

Graphite nanoplatelets were dispersed in varying quantities into a silicone matrix to form composite materials with higher thermal conductivities than the pure silicone matrix without sacrificing mechanical properties. It was found that the thermal conductivities of the composites increased with increasing GNP content as well as with increasing GNP particle size. The composites were found to be effectively electrically insulating, and it was found that the addition of GNP did ...

CO2-blown microcellular non-isocyanate polyurethane (NIPU) foams: from bio- and CO2-sourced monomers to potentially thermal insulating materials

Low-density microcellular non-isocyanate polyurethane (NIPU) foams were prepared using biological compounds and carbon dioxide. The morphology of these foams was investigated by scanning electron microscopy (SEM), and the thermal conductivity was determined using the transient plane source (TPS) method. It was concluded that a study needed to be undertaken to determine how to fine tune the morphology of the foams in order to decrease the thermal conductivity of the foams....
