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 ...
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 ...
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....
In this paper, cost efficient RVC foams were fabricated from household cleaning pad waste (CPW) and sucrose. A thermal analyzer measured the thermal conductivity of the RVC foams using the transient plane source (TPS) method. Results showed that the thermal conductivity of the CPW foams were significantly lower than Ultramet’s RVC foams which are highly insulative. This study proved that it is possible to reproduce low-cost carbon foams from ...
Thermally conductive pressure-sensitive adhesives (TC-PSA) are used in electronic devices and industrial applications. This paper examined how particle size, shape, and the addition of a coupling agent (GSP) affected the thermal conductivity of TC-PSA. A thermophysical properties analyzer measured the thermal conductivity of the particle-filled polymer using the transient plane source (TPS) method. Results showed that the thermal conductivity of the particles increased with diameter and aspect ratio, and the ...
