提出了一种在碳纳米管（纳米纤维）表面合成氮化硼涂层而不破坏管壁的方法。在中等温度下，硼酸与氨水在碳纳米管表面反应生成氮化硼（BN）涂层。碳纳米管的表面结构显著影响氮化硼涂层的形貌。如果碳纳米管表面无缺陷，则高度结晶化的绝缘BN纳米管可以封装碳纳米管。在无序壁结构的碳纳米管表面制备了多晶BN护套。
A method to synthesize boron nitride coating on the surface of carbon nanotubes (nanofibers) without damaging the tube walls has been developed. A reaction between boric acid and ammonia was performed at moderate temperatures on the surface of carbon nanotubes to form boron nitride (BN) coatings. The surface structure of the carbon nanotubes significantly influences the morphology of the boron nitride coating. If the surface of the tubes is free of defects, highly crystallized insulating BN nanotubes can encapsulate carbon nanotubes. On the surface of carbon nanotubes with disordered wall structure, a polycrystalline BN sheath was produced.
