1.发展了多种单一导电属性单壁碳纳米管可控制备方法。

　　提出了原位刻蚀—浮动催化剂化学气相沉积法，率先宏量可控制备出半导体性/金属性富集的SWCNT，被公认为是最有效的制备单一导电属性SWCNT的方法之一（J. Am. Chem. Soc. 2011, 133(14):5232；ACS Nano, 2013, 7:6831；ACS Nano, 2014, 8:7156）；设计制备了钴-铼高熔点双金属催化剂，通过热力学控制实现均一直径碳纳米管稳定形核，通过动力学调控实现催化剂和金属性碳纳米管低的结合能、与低能量和碳源供给，最终实现金属性碳纳米管相对快速生长，获得窄直径分布的金属性碳纳米管（ACS Nano 2022, 6, 1:232–2409）。

　　2.揭示了限制单壁碳纳米管（SWCNT）柔性透明导电薄膜性能的瓶颈，建立了管束尺寸调控和管间接触电阻调控新方法，实现了高光电性能SWCNT柔性透明导电薄膜的高效制备。

　　通过对浮动催化剂化学气相沉积系统内碳管生长的热力学和动力学条件优化，实现了“碳焊”、单根SWCNT薄膜的控制制备。研究发现，该碳焊结构可使金属性和半导体性碳管间的肖特基接触转变为欧姆接触，显著降低接触电阻，从而获得了在90%透光率下面电阻仅为25Ω/□的透明导电薄膜，比已报道性能提高2倍以上，已优于柔性基底上的ITO（Sci. Advances 2018, 4, eaap9264，日本专利6845259）。

　　3.发展了多种功能基元序构新方法，在柔性碳纳米管薄膜上构筑了单原子团簇、异质结、取向纳米晶等功能基元，开拓了高性能SWCNT薄膜在能量存储与转换、柔性传感、异质结太阳能电池、光电探测等领域的应用，推动了SWCNT薄膜的性能提升与应用。

　　利用具有优异透明导电特性的SWCNT薄膜为透明电极和空穴传输层，开展了SWCNT/Si异质结太能电池的构建与性能研究（Nano Energy 2018, 50:521; Nano Energy 2020, 69: 104442; Adv. Func. Mater. 2021, 31(37):2104396; J. Mater. Chem. A 2022, 10(9): 4644）；研制出多种碳纳米管复合电催化材料，设计、制备了多种柔性电催化剂一体化碳纳米管薄膜，组装、构建了高性能锌空电池及全固态柔性锌空电池等（Energ. Environ. Sci. 2016, 9:3079; NPG Asia Mater. 2018, 10:e461; Adv. Sci. 2019, 6:1802177; Appl. Catal.
