Low Melting-Point Alloy–Boron Nitride Nanosheet …

2020-4-24 · The interface thermal resistance (ITR) of thermal interface materials is discussed in terms of electronic unit heat dissipation. To reduce the ITR of heat-conducting silicone grease (HCSG), low melting-point alloys (LMPAs) are introduced using boron nitride nanosheets (BNNS) via a simple route for thermal management. The results reveal that LMPAs uniformly compound and coat BNNS at the ...
