Boron Nitride Nanotubes (BNNTs), which have structure similarity to carbon nanotube, have excellent mechanical, thermal, electrical, biocompatibility and neutron shielding properties which is of interests in a wide range of applications such as electrical insulators, thermally conducting, neutron shielding materials, drug delivery vehicles and pieozoelectric materials. In the previous study, we have developed hydrophlically functionalized BNNTs capped by the amphiphilic surfactants. However, for practical application of BNNTs like nanofiller, it is essential to control the structure of BNNTs in composite. To obtain the BNNTs structure control technique, we fabricated BNNTs/Block copolymer composites by mixing hydrophilically functionalized BNNTs with pluronic triblock copolymer. In this presentation, we report the phase transition of block copolymer and self-assembly of BNNT/Block copolymer composites due to effect of BNNT which were analyzed by small angle x-ray scattering (SAXS). |
