| 英文摘要 | Abstract—The improvements of digital devices over the past half century have brought an emerging challenge to thermal management in electronic packaging. Effective heat dissipation becomes a critical factor to ensure their speed, efficiency, and reliability. High thermal conductivity polymer composites have attracted increased attentions, with the purpose of removing more heat flow generated from power module. Currently, the common strategy to increase thermal conductivity is introducing fillers with inherent high thermal conductivity into the polymer matrix. Here we selected hexagonal boron nitride and alumina (Al2O3) microspheres as fillers for epoxy resign composites with reinforced thermal conductivity. In general, BN has the tendency to aggregate within polymer matrix , which will degrade the enhancement of thermal conductivity. To this end, we synthesized BN on the surface of alumina (Al2O3) microspheres to form distinct core-shell structure via high temperature calcination method using boric acid and urea as precursors. Then, epoxy composites, incorporated with Al2O3 and Al2O3@BN, respectively, were fabricated by doctor blading method. It is found that the core-shell structure plays important role. The prepared Al2O3@BN/epoxy composites with 60 wt% show a high in-palne thermal conductivity of 3.28 W/mk, 1.5 times that of Al2O3/epoxy and 16.4 times that of pure epoxy. This work indicates that fillers with core-shell structure have a promising application in fabricating high thermal conductive composites for next generation of light weight and high performance electronic devices. |
