Journal ArticleDOI
Mechanical and physical properties on carbon nanotube
TL;DR: In this paper, the aligned and very long carbon nanotubes were prepared by chemical vapor deposition (CVD) of hydrocarbon gas on various substrates, and properties such as tensile strength, Young's modulus, thermal conductivity and third-order optical nonlinearity were analyzed.
Journal ArticleDOI
Directly Synthesized Strong, Highly Conducting, Transparent Single-Walled Carbon Nanotube Films
Wenjun Ma,Li Song,Rong Yang,Taihua Zhang,Yuanchun Zhao,Lianfeng Sun,Yan Ren,Dongfang Liu,Lifeng Liu,Jun Shen,Zhengxing Zhang,Yanjuan Xiang,Weiya Zhou,Sishen Xie +13 more
TL;DR: Tests reveal that the directly synthesized SWNT films have superior electrical and mechanical properties compared with the films made from a solution-based filtration process: the electrical conductivity is over 2000 S/cm and the strength can reach 360 MPa.
Journal ArticleDOI
Large-scale synthesis of nitrogen-rich carbon nitride microfibers by using graphitic carbon nitride as precursor
Yuanchun Zhao,Zheng Liu,Weiguo Chu,Li Song,Zengxing Zhang,Dongli Yu,Yongjun Tian,Sishen Xie,Lianfeng Sun +8 more
TL;DR: One-dimensional structures of nitrogen-rich carbon nitride are synthesized via a thermal evaporation process as discussed by the authors, where the C-N atomic rings (s-triazine and/or tri-striazine) present in the precursor remain stable during the process and act as basic building blocks during microstructure assembly.
Journal ArticleDOI
Tensile tests of ropes of very long aligned multiwall carbon nanotubes
TL;DR: In this article, the authors measured the Young's modulus and tensile strength of multi-wall carbon nanotubes by pulling very long (∼2 mm) aligned nanotube ropes with a specially designed stress-strain puller.
Journal ArticleDOI
Controlled growth of single-walled carbon nanotubes by catalytic decomposition of CH4 over Mo/Co/MgO catalysts
Sing Hai Tang,Ziyi Zhong,Zhitao Xiong,Lianfeng Sun,Lei Liu,Jianyi Lin,Zexiang Shen,K. L. Tan +7 more
TL;DR: In this paper, it was found that the addition of molybdenum to Co/MgO catalysts could remarkably increase the yield and also improve the quality of single-walled carbon nanotubes (SWNTs) from catalytic decomposition of methane.
