Synthesis, Purification, Characterization, and Liquid Phases of BNNTs as Lightweight Multi-functional Precursor for Aerospace Fibers and Films
Abstract
We propose to accelerate BN nanotube (BNNT) development with the ultimate goal of providing high quality, high concentration BNNTs and the tools for analyzing them and converting them into neat, ordered structures via solution processing. To achieve this objective, the PI and co-PIs will develop a scientific understanding of (1) the synthesis of BNNTs; (2) purification of the synthesized BNNT products; (3) characterization of BNNTs in solid and liquid phases; (4) dissolution of BNNTs in true solvents; and (5) liquid crystalline behavior of BNNTs in solution. Because the processing framework closely parallels our earlier work with carbon nanotubes (CNTs), success in these five goals will enable the spinning of BNNT fibers, casting BNNT films, and molding of BNNT aerogels in our existing facility. Such macroscopic materials would then be tested for macroscopicthermal conductivity, strength, neutron shielding efficiency, and high temperature oxidation resistance.
