Nano-PCMs for passive electronic cooling applications

The authors have carried out an experimental and numerical study on the effects of seeding Al2O3 nanoparticles in a paraffin wax phase change material (PCM) on the thermal conductivity and the latent heat of fusion. It was determined that the addition of the nanoparticles (up to 1 wt. %) resulted in the nano-PCM having a higher thermal conductivity than the pure paraffin wax. The latent heat of fusion was also found ...

Processing of polyurethane/carbon nanotubes composites using novel minimixer

Polytetramethylene ether glycol (PTMEG) was used to functionalize multi-walled carbon nanotube (MWNT) by grafting to produce MWNT-g-PTMEG. These functionalized nanotubes were then dispersed in thermoplastic polyurethane (TPU) to form a TPU/MWNT nanocomposite. It was found that the functionalization resulted in improved dispersion of the nanotubes in the TPU material. The tensile strength and elongation at break of the nanocomposite were also enhanced by the addition of the nanotubes in ...

Influences of template concentration and epoxy functionality on porous epoxy systems: Characteristics of thermal stability, optical, dielectric, and mechanical properties

Porous epoxy thermosets were prepared using poly(ethylene glycol) (PEG) as a template. The two epoxies that were used to make the porous thermosets were diglycidylether bisphenol-A (DGEBA), and triphenylolmethane triglycidyl ether (TGTPM). Trimethylolpropane tris(poly(propylene glycol)), amine terminated)ether (T-403) was used as a hardener in producing the thermosets. The porous thermosets were then characterized to determine their structural, thermal, optical, dielectric, and mechanical properties, and the results ...

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 ...

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 ...
