Improved thermal conductivity of epoxy composites via linked boron nitride nanosheets with in-situ generated silver nanoparticles

Thermal management plays an important role in electrical and electronic systems. Owing to both excellent thermal conduction insulation, boron nitride nanosheets (BNNSs) are particularly attractive as fillers polymer composites. While the properties rely on connection of BNNSs matrices significantly. Herein, absorbed with silver acetate 2-ethyl-4-methylimidazole (Ag (2E4MI) 2 Ac) complex were prepared conductive for epoxy resin. During cure matrix, nano ions in-situ reduced, sintered bridged individual together. Therefore, contact resistance between decreased conducting networks effectively constructed. The conductivity increased from 1.26 W/mK composites only 2.35 BNNS/[Ag Ac] hybrids at 20 vol% content. Fitting measured results indicated that connections by silver. In addition, electrically insulating well preserved tensile strength containing interconnects was obviously improved.
