Since boron nitride nanotube (BNNT) has fabricated by Chopra in 1995, BNNTs have attracted many interests because of their excellent thermal and chemical stability compared with carbon nanotube (CNT). In the previous study, we have developed hydrophilically functionalized BNNTs capped by the Pluronic triblock copolymer that has both hydrophilic and hydrophobic group for their excellent dispersibility in aqueous solution. However, for practical application of functionalized BNNTs, it is necessary to control the BNNTs morphologies to improve their excellent properties. In order to control the morphologies of functionalized BNNTs, we evaporated the functionalized BNNTs to make self-assembled nanostructures, which were analyzed by using small angle X-ray scattering (SAXS) and polarization microscopy (POM). In this presentation, we report the solvent evaporation induced self-assembled nanostructures of functionalized BNNTs.
