High temperature thermal conductive nanocomposite textile by “green” electrospinning


Recently, thermal regulated textiles have attracted wide interest owing to the ability to realize personal cooling and provide thermal comfort. However, most of thermal conductive textiles cannot afford higher temperature (>200°C), which restricts the further applications in aviation, fire extinguishing or military requiring high temperature heat spreader. Here, we report a high temperature thermal conductive nanocomposite textile consisting of amino functional boron nitride nanosheets (FBN) and polyimide (PI) nanofibers. Notably, the textile is “green” electrospun from aqueous solution without any organic solvents, which is facile, economic and environmental. Moreover, both FBN and the precursor of PI are modified to be water soluble and exhibit good compatibility in the spinning solution even under high concentration. The “green” method obtained FBN-PI textile shows high thermal conductivity (13.1 W m−1 K−1) at high temperature (300 °C), filling in the gap of thermal conductive polymer nanocomposite fiber for high temperature thermal regulation. Furthermore, it also provides efficient cooling capability as thermal spreader. The good performance ascribes to the weaving of the aligned FBN filament in the thermal stable PI fiber, which constructs effective thermal conductive network. In addition, the nanocomposite textile is lightweight, soft and hydrophobic, which is promising for electronic packaging or space suit for special high temperature thermal management.
