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, ...
This article investigates the effects of two types of nanoparticles, OctaMethylOligomericSilsesquioxanes (OMPOSS) and carbon nanotubes (CNTs), in a model epoxy resin. Intumescent phosphorous-based flame-retardant (APP) was also incorporated with the CNTs. Thermal conductivity of nanocomposites was measured using a thermal analyser with the transient plane source method. Epoxy with APP and OMPOSS had increasing thermal conductivity below the glass transition temperature (Tg) but slowed above Tg. When APP and CNTs ...
It has been found that ZnO nanoparticles modify the curing behavior and crossed-line density, among other properties, in epoxy systems. This study aimed at studying the thermo-mechanical properties of ZnO nanoparticles. Thermal properties were measured using a transient plane source technique (TPS) in a thermal constants analyzer. The addition of ZnO nanoparticles caused a decrease of the thermally resistant joints. Despite high thermal conductivity of ZnO-NPs, there was high thermal ...
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 ...
