The aim of this study was to fabricate transparent polymers with high thermal conductivities for applications in electronic packaging. Characteristics of the inorganic filler, calcium fluoride (CaF2), and the polymer matrix were examined, and thermal conductivity was measured using a thermal analyzer based on the transient plane source (TPS) method. Results showed that the thermal conductivity of the composites increased with CaF2 content. This study was the first to report ...
The purpose of this study was to fabricate and analyze the physical properties of polyacrylate–gold nanocomposites (PGNs) with gold nanoparticles (GNPs) as their nucleation agents. The transient plane source (TPS) method was used to measure the thermal properties of the polyacrylate–gold nanocomposite foams (FPGNs) and PGNs. Results showed that the addition of GNPs improved thermal conductivity of the PGN materials, but as the size of GNPs increased, the ...
As nanotechnology becomes increasingly important, researchers are investigating methods to decrease the size of electronics. Carbon nanotubes (CNTs) have potential applications in nanoelectronics because of their high thermal conductivity and miniscule size. This study had many focuses, but a TPS used the transient plane source method to specifically measure the thermal conductivities of CNT-fabricated thermal pastes. Results showed that the thermal conductivities varied depending on filler content, but were comparable ...
Conductive polymer composites (CPCs) contain high concentrations of carbon nanotubes (CNTs) to maximize electrical conductivity. However, high nanoparticle concentrations degrade other important properties of CPCs. This study produced CPCs using ultrahigh molecular weight polyethylene (UHMWPE) fillers in place of CNTs in an attempt to maintain important physical and mechanical properties. A thermal analyzer measured the thermal conductivity of the CPC samples using the transient plane source (TPS) method. Results showed ...
In this paper, thermal properties of CdS and ZnS nanoparticles are examined to understand heat transfer behavior through polystyrene (PS) composites. The transient plane source (TPS) method was used to measure the thermal conductivities of the CdS/PS and ZnS/PS nanocomposites. Results showed that the nanocomposites followed a similar increasing trend until a common temperature where each sample adopted a constant thermal conductivity. Overall, the ZnS/PS nanocomposites showed ...
