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. ...

Boron Nitride filled epoxy composites are explored on a thermal and mechanical scale within this research article. Researchers took special interest in the effect of filler content, mixing conditions and Boron Nitride agglomerate size, on the thermal conductivity of the composite. Experimental results alluded to an increase in thermal conductivity, as filler content, and mixing speed, time and temperature increased. On the other hand, as the Boron Nitride agglomerate size ...

Catechins were added to boron nitride nanotube (BNNTs)/polyvinyl formal (PVF) composite films, in hopes of further increasing the thermal conductivity of the film. After thermal conductivity testing, the composite films were determined to have an increased thermal conductivity, as compared to their neat form. Researchers determined that the increase of thermal conductivity was related to the aromatic rings within the catechin, which interact with the nanotube surfaces. Upon contact, ...

In this study, researchers set out to determine the effects of embedding self-passivated aluminum fillers, of micro- and nano-meter size and various wt%, into a polyvinylidene fluoride matrix (Al*/PVDF). After testing, the results indicated an increase in thermal conductivity with the introduction of embedded self-passivated aluminum fillers. It was determined that the maximum thermal conductivity possible (3.258 W/mK) was achieved when the ratio of micro- to nano-sized particles was 20: 1, ...

In this article, researchers aim to improve the thermal management of Li-ion batteries, by introducing graphene fillers to hybrid phase change materials. The thermal management of any battery is dependent on the latent heat stored within the phase change material as it transitions phases. During this time, it is also crucial to reduce the chances of an internal temperature rise. Researchers used a thermal analyzer to determine the thermal conductivity ...
