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...
An intercalation nonlinear-optical (NLO) polyimide was synthesized by the ring-opening polyaddition of 4,4'-(Hexafluoroisopropylidene) diphthalic Anhydride (6FDA) and [(6-nitrobenzothiazol-2- yl)diazenyl]phenyl-1,3-diamine. Then, sol-gel technique was adopted, utilizing 3- aminopropyltriethoxysi- lane (APTES) and tetraethoxysilane (TEOS). The polyimide/silica hybrid material was obtained. The polyimide...
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...
