As an analogous material to carbon nanotube (CNT), boron nitride nanotube (BNNT) has been spotlighted due to its superb physical properties such as high mechanical strength, high elasticity, high thermal conductivity, high insulating property, unique luminescence, and biocompatibility. In this talk, we will present a non-covalent functionalization approach using poly(4-vinylpyridine) (P4VP) in order to efficiently debundle and achieve nano-dispersion of BNNTs. The efficiency and stability of BNNT nano-dispersion are systematically investigated. The highly debundled BNNT dispersion is utilized in fabrication of thermally regenerable ultrafiltration membranes which can exclude higher than 99.9% of latex with about 25 nm in diameter. In addition, the improved thermal conductivity of epoxy/hexagonal boron nitride (h-BN) composites and neutron shielding property of epoxy composite by addition of BNNTs will be introduced. |
