Recently, 2-D graphene nanoparticles produced by graphite exfoliation are a promising nanofiller for enhancing the thermal conductivity of polymeric materials. Unlike one-dimensional structures of carbon nanotubes, the 2-D structure provides reinforcement of polymer nanocomposites in two directions. In this article, multiwall carbon nanotubes (MWCNTs) and 2-D exfoliated graphite (EG), in a tetrafunctional epoxy resin, are investigated to determine the effect on thermal conductivity. Thermal conductivity measurements were carried out using ...
Nanocomposites are formed by combining conducting polymers and inorganic nanoparticles. In this study, nanocomposites of Ni-Zn ferrite were tested to determine the variation in their thermal properties. A thermal analyzer was used to measure thermal conductivity and thermal diffusivity of the composites using the transient plane source (TPS) method over a temperature range of 30 to 140°C. Results indicate that thermal conductivity and thermal diffusivity of Ni-Zn ferrites in a copolymer ...
Resin polymers, such as Polymethyl methacrylate (PMMA), have been used in denture fabrication because of their easy molding ability and flawless appearance. However, these PMMAs are not the most desirable material when dealing with mechanical strength, electrical conductivity and thermal stability. In this study, the addition of fillers, such as Nano-Aluminum Oxide (Nano-Al2O3) and plasma treated polypropylene (PP) fibers, to these polymers has been explored. Nanocomposites are desired in ...
This article is a review of the methods for measuring thermal conductivity including both steady state and transient methods. The article describes the experimental setup for each method, and it gives a brief description of the theory of each method. A review of models that have been developed for the prediction of thermal conductivity of polymeric nanocomposites is also presented....
The thermal conductivities of paraffin-based composite phase change materials (PCMs) containing different types of graphene nanoparticles were determined using the transient plane source method. It was determined that the thermal conductivity was increased by the addition of the nanoparticles, and the enhancement was greater for composites containing larger, and stiffer nanoparticles....
