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, ...

This research studied the addition of aluminum particles to an epoxy material, for use in micro-scale structures. For our interests, the thermal conductivity of the aluminum-epoxy composite was compared to that of the epoxy alone. Particle size was also taken into consideration during testing. It was determined that the epoxy-aluminum composite has a higher thermal conductivity, than the epoxy alone. Also noted, the larger the particle size, the more thermally ...

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 ...

Thermal interface materials are used to enhance the contact between two pieces of an electronic, to ultimately reduce the temperature and improve performance. This paper researches the contact resistance of curable polymer gels, a thermal interface material (TIMs). These TIM polymer gels have quite different mechanical properties thanks to the rheology of the polymer itself. Alongside physical testing, the researchers proposed a model to predict the thermal contact resistance of ...
