Asphalt solar collector (ASC) is a conductive asphalt concrete and an eco-friendly method to de-ice roadways. This study examined if the addition of conductive fillers and various mixing parameters could improve the thermal conductivity and energy efficiency of ASC. A thermal conductivity system measured the thermal conductivity of the concrete samples using the transient plane source (TPS) method. Results showed that thermal conductivity was mostly improved by higher asphalt temperatures, ...
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 ...
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 ...
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 ...
Synthetic polymers in starch-based polymer formulations improve the thermal and mechanical properties of the compounds. The purpose of this study was to develop and analyze foams containing ethylene-vinyl acetate (EVA) and varying concentrations of corn starch. A Thermal Constants Analyser measured the thermal conductivity of the EVA/starch samples using the transient plane source (TPS) method. Results showed that the thermal conductivity of the blends increased with starch content. The ...
