Polyether Ether Ketone (PEEK)/hexagonal boron nitride (h-BN) nanocomposites were formed by a planetary ball milling process and hot compression molding in order to determine the effect of the addition of h-BN on the properties of PEEK. In particular, the tensile strength, friction and wear behaviors, morphology, hardness, thermomechanical properties, and thermal conductivity of the nanocomposite were examined. Hexagonal boron nitride was added in filler concentrations of up to 5 wt. %. ...
The development of environmentally sustainable materials for use in the management of heat in electronics is becoming increasingly important. Currently the majority of materials that are used for this purpose are oil-based. In this article, the thermal transport, physical, electrical, and mechanical properties of a bio-based polymer matrix (polyactic acid) with embedded hexagonal boron nitride were studied to determine if this would be a practical material for use in the ...
The point of this research paper was to modify the thermal and mechanical properties of epoxy resin (EP) via the addition of boron nitride (BN) by a silane coupling agent (KH550). The use of 60 wt.% BN resulted in a thermal conductivity that was 5 times higher than the conductivity of the unmodified epoxy resin....
A variety of nano and micro-sized boron nitride (BN) particles were dispersed in a polyimide (PI) precursor polyamic acid (PAA) using a surfactant in order to generate a thermally conductive polyimide composite film with excellent thermal properties. The observed thermal conductivities varied with the BN weight % and the particle size. BN weight % was raised as high as 30%, which resulted in a thermal conductivity of 1.2 W/mK. Glass transition and thermal ...
This study aims to use Boron Nitride (BN) materials as thermo-conductive fillers to enhance the heat transfer in fluids. For this study, BN nanotubes, and nanospheres were added to fluids, to test for individual thermal enhancements. With the addition of BN nanotubes to water, the thermal conductivity of the fluid was enhanced by 2.6 times. Also noted, was the increase in conductivity of the fluid with the addition of BN nanospheres. ...
