In this study, a new type of sorption process was developed using activated carbon (AC) as a porous host to carry LiCl. A silica solution (SS) and expanded natural graphite treated with sulfuric acid (ENG-TSA) were added to increase heat transfer and mechanical strength of the composite. Thermal conductivities of the samples were measured using the Transient Plane Source (TPS) technique. Results found higher thermal conductivities directly correlated to larger ...
With a goal of wider usage of renewable energy sources that are clean and sustainable, effective technologies, such as thermal energy storage (TES), play a vital role in storing thermal energy for future use. In this study, silver nanoparticles were dispersed in paraffin wax, eicosane, as phase change material (PCM). Thermal conductivity was measured following the transient method, using a Thermal Constants Analyzer with transient plane source technique. Thermal conductivity ...
This article aims at assessing the impact of rice husk ash and volcanic ashes on the processing of porous inorganic polymers. The addition of volcanic ash or rice husk ash in porous Inorganic Polymer Composites (IPC) allows for the reduction of sodium silicate necessary, improving the Si/Al ratio. Thermal conductivity was measured using an instrument through the transient plane source method. With the addition of aluminum content and rounded ...
Thermal characteristics of polymer composites are similar to the properties of metal, with the mechanical properties being similar to plastics. Thermal conductivity of a polymer composite depends on geometry of the filler, and interaction and dispersal of the filler within the polymer matrix. In this study, thermal conductivity of copper and Al₂O₃ filled polymer composites were investigated. A Thermal Constant Analyzer was used to measure thermal conductivity of the ...
To improve the thermal conductivity of polymeric matrixes, conducting fillers were added to polymers, specifically graphite, having good thermal conductivity and dispersibility. Exfoliated graphite (EG) and graphite nanoplatelets (GNP) are excellent alternatives to metal and carbon as conductive polymer composites, through solution mixing and melt blending techniques. Thermal conductivity of composites was measured by a thermal analyzer, using the transient plane source (TPS) method. Solid-state shear milling treated composites showed ...
