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, ...

The purpose of this research was to improve the thermal conductivity of boron-nitride filled epoxy composites. To complete this task, the interfacial adhesion in the composite needed to be improved. This was achieved by employing admicellar polymerization to coat the polystyrene and polymethyl methacrylate, on the boron nitride surface. The results indicated an increase in the thermal conductivity of the composite from 1.5 W/mK, with the use of untreated boron-nitride, ...

The focus of this research was to discover new thermally conductive ceramic/plastic composites for their use in thermal management. In this experiment, the thermal constants analyzer was used to measure the thermal conductivity of composite films containing hexagonal boron nitride particles and polyimide. Upon testing, a thermal conductivity of 7 W/mK with a 60% filler content was noted, as compared to a thermal conductivity of 5 W/mK for the plastic ...

In this experiment, the thermal conductivity of several composites, with varying matrix composition and boron nitride nanotubes fillers, was investigated. Poly(methyl methacrylate), polystyrene, poly(vinyl butyral) and poly(ethylene vinyl alcohol) were the matrix compositions analyzed. The results indicated that with the addition of the boron nitride nanotube fillers, there was a 20-fold increase in the thermal conductivity of the polymer. Several other properties were analyzed alongside of thermal ...
