Compared to traditional epoxy, polybenzoxazine resins have improved thermal, mechanical, and electrical properties. In this article, spherical aluminum nitride (AIN) was studied as a filler in bisphenol A-aniline-based polybenzoxazine (poly(BA-a)). Thermal conductivity was obtained by transient plane source method. Thermal conductivity of each composite gradually increased with enhanced filler amount. Poly(BA-a)/AIN composites also had higher thermal conductivity than systems containing epoxy/AIN....
This study looked at the use of two different fillers to improve the thermal properties of an epoxy resin. The two fillers were multi-walled carbon nanotubes (MWCNTs) and aluminum nitride (AlN). Through the use of poly(glycidyl methacrylate) (PGMA) and a zirconate coupling agent the MWCNTs and AlN particles respectively were added to the epoxy resin. Through the use of 1 vol.% MWCNT and 25 vol.% AlN the researchers were able to ...
Using magnetic striation and ultrasonic agitation, aluminum nitride particles were dispersed into ethanol. The method was used to measure the thermal conductivities of these aluminum nitride-ethanol nanofluids. Results show about 20 % increase in the thermal conductivity of ethanol and a strong temperature dependence of the thermal conductivity....
