Closed-cell carbon foams from diphenolic acid-based polybenzoxazine

Carbon foams were prepared from diphenolic acid-based benzoxazine foams by pyrolysis under nitrogen atmosphere. The method used in this article produced foams containing a large fraction of closed cells which is uncommon for carbon foams. The foams studied were found to possess similar mechanical properties common to other carbon foams; however, the presence of the high fraction of closed cells led to the lowest observed thermal conductivity ever reported for ...

Effect of the pore volume fraction on the thermal conductivity and mechanical properties of kaolin-based foams

Very porous ceramics were prepared by the direct foaming method containing 79% kaolinite , based on commercial clay. Ceramics were prepared with different pore volume fractions, and the different ceramics were analyzed using the transient plane source (TPS) technique to measure thermal conductivity. Increasing pore volume fraction led to decreased thermal conductivity....

Functionalized graphene sheet filled silicone foam nanocomposites

The authors report the synthesis of a novel functionalized graphene sheet (FGS)/silicone porous nanocomposite with varying concentrations of FGS. The physical and thermal properties of the synthesized nanocomposites were studied in depth. SEM and TEM were used to elucidate the physical microstructure of the materials, and the transient plane source (TPS) technique was used to measure thermal conductivity. The nanocomposite showed an increased thermal conductivity as compared to the ...

Properties and Performance of High-Purity Thermal Barrier Coatings

Using the transient plane source (TPS) technique, the authors investigated the thermal properties of a series of yttria-stabilized zirconia (YSZ) thermal barrier coatings (TBCs). The YSZ coatings had varying amounts of impurities (Zr, Y, Si, Al oxides) and the amount of impurity affected the post-spray properties of the coating. TBCs are exposed to high temperatures during their regular operation, which can lead to the degeneration of the coating if the ...

Effects of Impurity Content on the Sintering Characteristics of Plasma-Sprayed Zirconia

Yttria-stabilized zirconia (YSZ) powders containing varying amounts of SiO2 and Al2O3 impurities were plasma sprayed onto metallic substrates and subsequently investigated. The authors were interested in how the impurities affected sintering rates, thermal conductivity, linear contraction, and pore size and architecture among other things. The YSZ coatings were heat treated at 1400°C for 10 hours and then analyzed for the properties mentioned above. A machine was used to measure the ...
