A kind of form-stable phase change material (PCM) based on capric-lauric acid eutectic acting as the heat-absorbing material and nano silicon dioxide serving as the supportive material was prepared by sol-gel method. The optimal proportion of the capric-lauric acid eutectic in the composite was determined as 60 wt.%. By the effect of capillarity and hydrogen bonding, fatty acid eutectic can be immobilized...
Thermally conducting and effectively electrically insulating nanocomposites for thermal interface applications were developed by dispersing graphite nanoplatelets (GNP) into a silicone matrix by dual asymmetric centrifuge mixing. Thermal conductivity, electrical conductivity, compression and hardness properties of the resulting composites were measured. The effects of GNP particle size and wt.% of...
Clathrate Ba8Al16Si30 was produced by arc melting and hot-pressed and effects on the microstructure and thermoelectric properties were investigated. The ingot was crushed into powders in a glove box. The powders were hot-pressed at 1,073, 1,123 and 1,173K using a stress of 60 MPa for 2 hours. The phase transformation behavior of hot-pressed Ba8Al16Si30 was examined by thermo-gravimetric analysis (TGA),...
The need for faster, smaller, and more reliable and efficient products has resulted in increase of heat generated in microelectronic components. The removal of the heat generated is an important issue in electronic packaging. The present research work aims at developing a new class of nano-thermal interface material (nanoTIM) that has low thermal resistance, high thermal conductivity and mechanical...
To improve mean-life and reliability of power cable, we have investigated specific heat and thermal conductivity of XLPE insulator and semiconducting materials in 154 kV XLPE cable. Specimens were respectively made of sheet form with EVA, EEA and EBA with carbon black 30 wt%, and the other was made of sheet form by cutting XLPE insulator in certain 154 kV power cable. Specific heat and thermal conductivity...
