The purpose of this this study was to graft polymer chains onto the surface of carbon nanotubes (CNTs) to examine the morphology and thermal properties of the epoxy composites in comparison to multiwalled carbon nanotubes (MWCNTs). A thermal analyzer measured the thermal conductivity of the nanocomposites using the transient plane source (TPS) technique. Results showed that the addition of Glycidyl methacrylate (GMA) to the MWCNTs/epoxy composites significantly enhanced thermal ...
Phosphosilicate ceramics with varying compositions were synthesized through the sol-gel process and the thermal conductivity of the samples was measured using the transient plane source (TPS) method. Results showed that the thermal conductivity of phosphosilicate ceramic powder was low, but increased slightly with phosphorous concentration. The low thermal conductivity of the ceramics could be useful in thermal barrier applications....
Despite its fragility, poor thermal properties, and high water sorption rates, polymethyl methacrylate (PMMA) is commonly used in denture fabrication. This study aimed to examine how the addition of Aluminum oxide nanoparticles affected the properties of PMMA. A thermal constant analyzer measured the thermal properties of the Al2O3 nanoparticles using the transient plane source (TPS) method. Results showed that the thermal conductivity and thermal diffusivity of acrylic resin improved ...
This study developed a model that used a transient plane source (TPS) sensor to measure the specific heat capacity of anisotropic materials. The underside of a sample holder with a diameter of 20 mm, and a height of 5 mm was attached to a Kapton TPS sensor. During measurements, the sample holder was hung inside a steel tube at atmospheric pressure. Results showed that the model underestimated the heat capacity, which suggests ...
Non-isocyanate polyurethane (NIPU) have the potential to replace polyurethane (UP) foams in the future. This study attempts to synthesize non-isocyanate polyurethane (NIPU) at room temperature for the first time. A TPS instrument measured the thermal conductivity of the foams using the transient plane source (TPS) method. Results showed that foams prepared with 10 or 20% of PPOBC640 had the highest thermal conductivities. NIPU foams had a slightly higher thermal conductivity than PU ...
