Nanocomposite fabrics with high content of boron nitride nanotubes for tough and multifunctional composites

Abstract Herein, we apply a one-step filtration method to obtain boron nitride nanotube (BNNT)-based fabrics incorporating high content of BNNTs and an adhesive thermoplastic polyurethane (TPU). The adsorption behavior TPU on different qualities functionalized was evaluated in two-solvent system contrasted with carbon nanotubes, pointing differences surface interaction. BNNT quality affected not only the nanocomposite mechanical properties but also trends as function increasing adhesion substrates. Samples containing higher materials showed up 12-fold improvement Young’s modulus, while functionalization improved tensile toughness. Thermal conductivity varied between 1.5 3 W m ?1 K depending primarily without pronounced effect from BNNTs. BNNT-TPU fabric offers promising format exploit within tough, electrically insulating, thermally conductive for heat dissipation packaging or electronics. Graphical abstract
