Abstract

In this work, new boron nitride-reinforced epoxy-based composite inks for direct-ink write (DIW) additive manufacturing are presented. Printed composites are characterized for thermal conductivity, flexure, and impact energy, along with optical and electron microscopy. The new inks utilize boron nitride nanobarbs (BNNBs), a novel form of boron nitride nanotube, where the surface is decorated with hexagonal boron nitride nanoplatelets. BNNBs are shown to improve the thermal conductivity of the printed composites up to 32%, the strength up to 34%, and stiffness up to 44%. Anisotropy was observed in all measurements, suggesting that the BNNBs become aligned during printing.
