This article studied the thermal conductivity values and measurements for the following two systems using the transient hot wire (THW) and transient plane source (TPS) techniques: ethylene glycol with added CuO, TiO2, or Al2O3 nanoparticles and water with added TiO2 or Al2O3 nanoparticles or multiwall carbon nanotubes (MWCNTs). A TPS technique using a thermal conductivity analyzer ...
The article investigated the hybridization of multi wall carbon nanotubes (MWCNTs) with filler in polymer matrix composites (PMC) which is one of the techniques used to combine different properties of fillers to make more unique composites. The properties of two different hybrid filler composites (Chemical Vapour Deposition (CVD) hybrid filler and physically hybrid filler) were then studied. The thermal conductivity was measured through the use of a Thermal Constant Analyzer ...
Thermally conductive polymers are the most effective and economic methods of removing heat accumulation from microelectronics. In the present study, m-xylylenediamine (MPDA) was used as a curing agent for the epoxy matrix and analyzed for its effect on the thermal conductivity of the composite. Thermal conductivity was measured with a thermal analyzer using the transient plane source (TPS) method. When filling content of the multiwall carbon nanotubes (MWNTs) was 2%wt, ...
The authors present a method of preparation of TiO2 nanotubes by alkaline treatment (with NaOH) of TiO2 particles followed by acid-washing and annealing treatment. Theoretical and experimental studies on the thermal conductivity of TiO2 nanotubes is also presented. The thermal conductivity values determined experimentally matched well with theoretical values obtained. It was found that TiO2 nanotubes had a lower thermal conductivity than the original TiO2 particles. This phenomenon was attributed ...
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 ...
