我们首次报道氮化硼纳米管（BNNT）可以通过用聚合物包裹而溶解在有机溶剂中。透射电子显微镜和阴极发光研究表明 BNNT 和聚合物之间存在强烈的 π−π 相互作用。通过对复合薄膜和由溶液制备的 BNNT 薄膜进行紫外-可见光吸收实验，记录了 BNNT 的带隙范围为 5.2 至 5.5 eV，与其几何特征无关。
We report for the first time that boron nitride nanotubes (BNNTs) may be dissolved in organic solvents by wrapping them with a polymer. Transmission electron microscopy and cathodoluminescence studies indicate the strong π−π interactions between BNNTs and the polymer. A band gap ranging from 5.2 to 5.5 eV was documented for the BNNTs independent of their geometrical characteristics by using ultraviolet−visible absorption experiments on composite films and thin BNNT films prepared from solutions.
