Abstract: 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 catechin positions itself between the BNNTs and a polymer, improving the heat transfer between the matrix and fillers.
