报道了一种宏观量制备长、小直径、单壁和少壁氮化硼纳米管（BNNT）的新方法。加压蒸气/冷凝器（PVC）方法在没有催化剂的情况下产生高度结晶的、非常长的、小直径的BNNT。手掌大小的棉花状BNNT原料块通过这种技术生长，并直接纺成厘米长的纱线。观察到的纳米管长度是最密切相关的方法生长的纳米管长度的100倍。这些长BNNT的自组装和生长模型进行了讨论。
A new method for producing long, small-diameter, single- and few-walled, boron nitride nanotubes (BNNTs) in macroscopic quantities is reported. The pressurized vapor/condenser (PVC) method produces, without catalysts, highly crystalline, very long, small-diameter, BNNTs. Palm-sized, cotton-like masses of BNNT raw material were grown by this technique and spun directly into centimeters-long yarn. Nanotube lengths were observed to be 100 times that of those grown by the most closely related method. Self-assembly and growth models for these long BNNTs are discussed.
