Abstract

This research focuses on the synthesis and characterization of gigantic carbon micro-tubes (CMTs) via a simple, low-cost, low-pressure (10–15 kPa) CVD method. The design, construction of the CVD setup, and the development of the synthesis technique and methodology were realized by our research group. Gigantic CMTs were synthesized using gas (propane) and liquid (acetonitrile, ethanol, and toluene) carbon sources. The synthesized materials were thoroughly analyzed using SEM, EDX, Raman spectroscopy, and X-ray diffraction. SEM analysis revealed that the diameters of CMTs exceed the literature results to date, reaching 34.48 μm. Carbon structures synthesized from propane gas, ethanol, and toluene were assigned to the CT structure; meanwhile, from acetonitrile, carbon fibers (d = 9-44,4) μm; (l = 700-800) μm were synthesized. The obtained results proved that the carbon source type directly impacts the diameter (ethanol (9-20) μm; toluene (3,57-7,36) μm), and length (ethanol (l = 500-600) μm; toluene (l = 80- 90) μm; propane gas (l = 500-600) μm of the CMTs. Raman spectroscopy showed low disorder in the structure of CMTs compared to CFs. The grown CMTs have a great potential for microelectronic devices, composite materials, environmental protection, etc.

低成本低压化学气相沉积（CVD）法制备大直径碳微管及其表征

本研究主要通过简单、低成本、低压（10-15 kPa）的CVD方法合成和表征巨型碳微管（cmt）。本课程组完成了CVD装置的设计、搭建以及合成工艺和方法的开发。利用气体（丙烷）和液体（乙腈、乙醇和甲苯）碳源合成了巨型碳纳米管。对合成材料进行了SEM、EDX、拉曼光谱和x射线衍射分析。SEM分析表明，cmt的直径达到34.48 μm，超过了迄今为止的文献结果。由丙烷气、乙醇和甲苯合成的碳结构被分配到CT结构；同时，从乙腈中分离出(d = 9-44,4) μm的碳纤维；（l = 700 ~ 800） μm。结果表明，碳源类型直接影响了乙醇(9-20)μm；甲苯(3,57-7,36)μm)，长度(乙醇(l = 500-600) μm；甲苯(l = 80- 90) μm；丙烷气(l = 500-600) μm的cmt。拉曼光谱显示cmt的结构无序性较低。生长的cmt在微电子器件、复合材料、环境保护等方面具有巨大的潜力。

期刊介绍： Solid State Communications is an international medium for the publication of short communications and original research articles on significant developments in condensed matter science, giving scientists immediate access to important, recently completed work. The journal publishes original experimental and theoretical research on the physical and chemical properties of solids and other condensed systems and also on their preparation. The submission of manuscripts reporting research on the basic physics of materials science and devices, as well as of state-of-the-art microstructures and nanostructures, is encouraged. A coherent quantitative treatment emphasizing new physics is expected rather than a simple accumulation of experimental data. Consistent with these aims, the short communications should be kept concise and short, usually not longer than six printed pages. The number of figures and tables should also be kept to a minimum. Solid State Communications now also welcomes original research articles without length restrictions. The Fast-Track section of Solid State Communications is the venue for very rapid publication of short communications on significant developments in condensed matter science. The goal is to offer the broad condensed matter community quick and immediate access to publish recently completed papers in research areas that are rapidly evolving and in which there are developments with great potential impact.
