随着高通量合成技术的不断进步，氮化硼纳米管的研究正朝着应用方向发展。一个未来的目标是组装高纵横比、原始bnnt的宏观物品。然而，由于提纯和制造方法的不足，目前还无法获得这些物品。我们介绍了一种无需超声波或使用表面活性剂就能从合成杂质中提取bnnt的溶液工艺，并将提取的bnnt转化为薄膜。溶液法还可用于将含有大量六方氮化硼（h-BN）的合成材料转化为具有可控结构和尺寸的席子和气凝胶。溶液萃取法，结合合成和纯化的进一步进展，有助于全bnnt宏观物品的发展，如纤维和三维结构。
Due to recent advances in high-throughput synthesis, research on boron nitride nanotubes (BNNTs) is moving toward applications. One future goal is the assembly of macroscopic articles of high-aspect-ratio, pristine BNNTs. However, these articles are presently unattainable because of insufficient purification and fabrication methods. We introduce a solution process for extracting BNNTs from synthesis impurities without sonication or the use of surfactants and proceed to convert the extracted BNNTs into thin films. The solution process can also be used to convert as-synthesized material-which contains significant amounts of hexagonal boron nitride (h-BN)-into mats and aerogels with controllable structure and dimension. The solution extraction method, combined with further advances in synthesis and purification, contributes to the development of all-BNNT macroscopic articles, such as fibers and 3-D structures.
