A variety of nano and micro-sized boron nitride (BN) particles were dispersed in a polyimide (PI) precursor polyamic acid (PAA) using a surfactant in order to generate a thermally conductive polyimide composite film with excellent thermal properties. The observed thermal conductivities varied with the BN weight % and the particle size. BN weight % was raised as high as 30%, which resulted in a thermal conductivity of 1.2 W/mK. Glass transition and thermal ...

The addition of ceramics, Boron Nitride and Boron-Aluminum Nitride, to an organosoluble polyimide (PI) film was investigated in this research. Test were performed to determine the effect of the addition of ceramics, on the thermal performance of the film, at room temperature. After appropriate treatments, the BN-PI elicited a thermal conductivity of 2.3 W/mK, as compared to the neat polyimide, with a thermal conductivity of 0.13 W/mK. In contrast, due ...

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 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 ...
