Abstract: Aluminium nitride(AlN) was chemically modified using silane coupling agent KH-560 and then
combined with matrix material(epoxy) to prepare AlN/epoxy thermal conductive adhesives in which
modified AlN served as thermal conductive filler. Fourier transform infrared spectrometer, scanning
electron microscope, thermal gravimetric analyzer and thermal constants analyzer were used to characterize
the structure and properties of the adhesives. The experimental results showed that coupling agent molecule
was successfully chemically grafted onto the surface of AlN. The modified AlN had strong interface
adhesion with epoxy. The introduction of modified AlN could significantly improve the thermal stability
and thermal conductivity of the obtained epoxy adhesives. When the mass fraction of AlN was 70% of the
mass of the adhesive, the thermal conductivity of the modified AlN/epoxy adhesive was 2.24 W/(mK),
while that of the AlN/epoxy adhesive was only 1.73 W/(mK). Furthermore, a series of modified AlN/
graphene oxide (GO)/epoxy adhesives were prepared to further improve its thermal conductivity. The
adhesive containing 50% mass fraction of modified AlN and 3% mass fraction of GO reached a thermal
conductivity of 3.05 W/(mK).
