迄今为止，关于由碳/氮化硼核-壳异质纳米管（MWCNT@BNNT）或氮化硼纳米管（BNNT）组成的宏观片材组件（特别是巴基纸）的制造和性质的报道有限。在本文中，我们报道了通过一种简单的方法合成MWCNT@ BNNT，该方法涉及大气压化学气相沉积（APCVD）和安全的h-BN前体氨硼烷。这些MWCNT@ BNNT被用作通过核碳的热氧化合成BNNT的牺牲模板。通过简易超声处理和过滤步骤促进巴克纸制造。为了测试这些新的巴基纸的导热性能，在热管理应用的利益，我们已经开发了一种新的技术，先进的扫描热显微镜（SThM），我们称之为穿刺SThM（pSThM）。我们的测量结果表明，相对于对照多壁碳纳米管（MWCNT）巴克纸，MWCNT@BNNT巴克纸的热导率增加了14%。同时，我们的BNNT巴克纸表现出大约一半的MWCNT对照的热导率，这归因于我们的BNNT的乱层质量。据我们所知，这项工作实现了MWCNT@BNNT巴克纸和由BNNT组成的BNNT巴克纸的第一次热导率测量，而BNNT巴克纸不是通过高能技术合成的。
To date, there has been limited reporting on the fabrication and properties of macroscopic sheet assemblies (specifically buckypapers) composed of carbon/boron nitride core–shell heteronanotubes (MWCNT@BNNT) or boron nitride nanotubes (BNNTs). Herein we report the synthesis of MWCNT@BNNTs via a facile method involving Atmospheric Pressure Chemical Vapor Deposition (APCVD) and the safe h-BN precursor ammonia borane. These MWCNT@BNNTs were used as sacrificial templates for BNNT synthesis by thermal oxidation of the core carbon. Buckypaper fabrication was facilitated by facile sonication and filtration steps. To test the thermal conductivity properties of these new buckypapers, in the interest of thermal management applications, we have developed a novel technique of advanced scanning thermal microscopy (SThM) that we call piercing SThM (pSThM). Our measurements show a 14% increase in thermal conductivity of the MWCNT@BNNT buckypaper relative to a control multiwalled carbon nanotube (MWCNT) buckypaper. Meanwhile, our BNNT buckypaper exhibited approximately half the thermal conductivity of the MWCNT control, which we attribute to the turbostratic quality of our BNNTs. To the best of our knowledge, this work achieves the first thermal conductivity measurement of a MWCNT@BNNT buckypaper and of a BNNT buckypaper composed of BNNTs not synthesized by high energy techniques.
