Thermal properties of green alumina porcelain

The thermal properties, as well as bulk density, and mass loss of alumina porcelain were determined as a function of firing temperature. It was found that after sintering at 1320 ºC, the thermal conductivity and thermal diffusivity increased by ~700% and ~400%, respectively....

Improved Thermal Conductivity of Poly(trimethylene terephthalate-block-poly(tetramethylene oxide) Based Nanocomposites Containing Hybrid Single-Walled Carbon Nanotubes/Graphene Nanoplatelets Fillers

Poly(trimethylene terephthalate)-block-poly(tetramethylene oxide) (PTT-PMTO) copolymer-based nanocomposites containing a combination of single-walled carbon nanotubes (SWCNTs) and graphene nanoplatelets (GNPs) as carbon nanofillers were investigated to determine their thermal conductivities. Nanocomposites having a total carbon nanofiller concentration of 0.4 and 0.6 wt. % were preparared with varying amounts of each nanofiller, and the thermal conductivity was measured using the transient plane source (TPS) method. The dispersion of the nanofillers was observed by ...

Thermal conduction through diamond – silicon heterostructures

The thermal conductivity and thermal boundary resistance between ultrananocrystalline diamond (UNCD) and microcrystalline diamond (MCD) films on silicon wafers were evaluated. It was found that the MCD/Si composite wafers were more thermally conductive than the UNCD/Si wafers over the temperature range tested. It was also found that in both types of composite wafer, the thermal conductivity increased with temperature in contrast to the decrease that is observed in ...

Measurement of Thermal Transport Properties in Metal Doped Polypyrrole

Metal doping of a polypyrrole matrix was carried out. Nickel and Cobalt were the two metals that were used in this study, and three samples were prepared, one containing 100% Co, one containing 50% Co and 50% Ni, and finally, one containing 100% Ni. The effective thermal conductivity and thermal diffusivity were evaluated, and it was determined that metal doping of the polymer matrix resulted in increases in both the thermal conductivity, and the ...

Percolation based enhancement in effective thermal conductivity of HDPE/LBSMO composites

La0.7Ba0.15Sr0.15MnO3 (LBSMO) powder was prepared and mixed with HDPE powder in volume fractions from 0 to 0.30. These powders were then molded into pellet form in a hot press and cooled to room temperature. The thermal conductivity of the resulting composite was then measured using the transient plane source method. It was found that the thermal conductivity of the composite samples increased with increasing LBSMO content up to an ...
