Characterization of the structure, acoustic property, thermal conductivity, and mechanical property of highly expanded open-cell polycarbonate foams 

This study was conducted to determine if highly expanded open cell polycarbonate foams (PC) could be used as thermal insulation among other characteristics of the foam. This was accomplished through testing the PC foam with the Transient Plane Source (TPS) method. Multiple relative densities of foam were tested, and it was found that the higher the relative density the higher the thermal conductivity, and vice versa. The lower the relative ...

One-pot synthesis, characterization and properties of acid-catalyzed resorcinol/formaldehyde cross-linked silica aerogels and their conversion to hierarchical porous carbon monoliths

Aerogels are ultra-light, insulative, porous materials that have a wide variety of applications. The aim of this study was to synthesize resorcinol/formaldehyde (RF) cross-linked silica aerogels in one pot by acid catalysis. A thermal constant analyzer measured the thermal conductivity of the RF/SiO2 aerogels using the transient plane source (TPS) method. Results showed that although the RF/SiO2 aerogels had a lower density, their thermal conductivities resembled those ...

Biomass-derived, thermally conducting, carbon foams for seasonal thermal storage

Seasonal thermal storage based on phase change materials (PCMs) require a thermally conductive host because they typically have low thermal conductivities. In this study, tannin-based composite carbon foams were prepared using thermally conductive exfoliated graphite (EG) fillers and pMDI additives. A thermal analyzer measured the thermal conductivity of the samples using the transient plane source (TPS) method. Results showed that the EG-carbon foams and the EG/pDMI-carbon foams showed significantly ...

Enhanced thermally conductivity and mechanical properties of polyethylene (PE)/boron nitride (BN) composites through multistage stretching extrusion

This study aimed to enhance the thermal and mechanical properties of polyethylene (PE)/boron nitride (BN) composites by manipulating the BN concentrations in the matrix and by applying shear fields in laminating-multiplying elements (LMEs). A thermal constants analyzer measured the thermal conductivity of the PE/BN composites using the transient plane source (TPS) method. Results showed that the thermal conductivity of the composites increased with BN concentration. As well, the ...

Mechanical, thermal and electrical properties of aluminum nitride/polyetherimide composites

In this study, aluminum nitride was treated with silane in an attempt to improve the performance of polyetherimide (PEI) composites. Various properties of the modified AlN/PEI composites were examined including the thermal conductivity by way of a thermal analyzer based on the transient plane source (TPS) method. Results showed that the AlN filler improved dispersion and interface of the matrix which enhanced the thermal conductivity of the PEI composites....
