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 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 ...
