| 1 | 碳纳米管的宏量制备及产业化显示文摘作为纳米材料的代表之一,碳纳米管因其独特的一维结构具备了优异的力学、电学、热学、光学和反应性能,使其在能源存储与转化、复合材料、多相催化、环境保护及生物医药等领域具有大量的应用潜力.本文总结了多种类型碳纳米管宏量制备的化学及工程原理,并对多壁碳纳米管、单壁碳纳米管、双壁碳纳米管、定向碳纳米管、超顺排碳纳米管、水平超长碳纳米管、掺杂碳纳米管、螺旋碳纳米管、碳纳米管结及碳纳米管/石墨烯杂化物的宏量制备方法进行了评述.同时,对碳纳米管产业化中新的工程问题,如工业标准、环境评估以及产业化进展进行了分析.目前,碳纳米管已经具有成千吨的产能,并广泛应用于锂离子电池电极、导电复合材料、汽车配件和体育用品等领域.尽管如此,高性能的碳纳米管的宏量制备及其配套产业化技术仍有待深入开发,产品需要进一步丰富、市场需要进一步拓展,以望形成大规模纳米产业,促进社会的可持续发展. | 张强 黄佳琦 赵梦强 骞伟中 魏飞 | 2013 | 中国科学:化学2013，43，6： | 22 |
| 2 | Preface显示文摘In the last two decades, carbon nanotubes (CNTs) have attracted tremendous attention. A CNT can be considered a seamless cylinder formed by rolling up graphene sheets, which are composed of hexagonal sp2 carbon networks.

| 3 | Different effects of substrates on the morphologies of single-walled carbon nanotubes显示文摘In this work,different effects of substrates on the morphologies of single-walled carbon nanotubes(SWNTs)are studied.SWNTs were produced by floating catalytic chemical vapor deposition using CH4as carbon source gas and Ar as carrier gas.Then the SWNTs were deposited on lithography-patterned different substrates.The as-grown SWNTs at the boundaries between SiO2and metal were characterized by scanning electron microscopy,atomic force spectroscopy and Raman spectroscopy.It is found that SWNTs deposited on low-conductivity substrates trend to have curved morphologies and some of them form rings,while SWNTs deposited on metal substrates remain straight and orientated.The mechanism of these effects was also discussed,which is closely related to the thermal conductivities and the principle of energy dissipation. | Li Tao Gang Wang Fang Yu Lianfeng Sun | 2014 | Chinese Science Bulletin2014，59，19： | 1 |
| 4 | Precise Synthesis of Carbon Nanotubes and One-Dimensional Hybrids from Templates显示文摘Carbon nanotubes(CNTs)present unique properties determined by their chiral structure.The main hurdle towards the wide applications is the difficulty to control the structure of CNTs and their hybrids that determines the properties.Precise synthesis with well-defined templates is a promising approach to control the identical structure of carbon nanomaterials.In this review,we summarize main achievements on controlled synthesis of CNTs and hybrids on two aspects:chirality-specific growth of CNTs from well-defined catalysts and nanocarbon templates,atomically precise synthesis of one-dimensional(ID)materials with the templates of CNTs.In the chirality-controlled growth part,we focus on the design of structural templates and growth mechanisms.In the synthesis of CNT hybrids part,we organize the existing strategies based on types of ID hybrids templated by CNTs,including confined nanotubes,linear carbon chains,nanowires,quasi-ID van der-Waals materials.The main advantages,challenges,and perspectives in further development are discussed. | Xusheng Yang Xin Zhao Tianhui Liu Feng Yang | 2021 | Chinese Journal of Chemistry2021，39，6： | 0 |
| 5 | The influence of probe lift-up height on CNT electrical properties measurement under EFM DC mode显示文摘Nowadays,one of the bottlenecks which hinder the development and application of carbon nanotube(CNT)nano device is that no pure semiconducting CNT(s-CNT)or metallic CNT(m-CNT)can be obtained,and for solving this problem scientists proposed some methods on preparation or separation,but all the results still should be detected and feedback to the process for further improving the preparation and separation methods.Thus,it is very important to measure and distinguish the electrical properties of CNT.For that,scientists proposed a method to measure CNT electrical properties based on DC electrostatic force microscope(EFM)mode,which distinguishes m-CNT from s-CNT according to different scan line shape to CNT with different electrical properties.But,we discovered that the probe lift-up height will seriously affect the shape of the scan line,which makes this method not reliable in distinguishing m-CNT from s-CNT.In this paper,the authors deeply researched the influence of probe lift-up height and also gave corresponding theoretical analysis and explanation,which will greatly improve the method of detecting CNT electrical properties by EFM. | Zengxu Zhao Xiaojun Tian Jie Liu Zaili Dong Lianqing Liu | 2014 | Chinese Science Bulletin2014，59，14： | 0 |
