Synthesis of Carbon Nanotubes via Plasma Arc Discharge Method

CNTs are the element that exists with predominant physio-chemical properties, which have been extensive researched today. These properties make carbon nanotubes (CNTs) valuable in a wide potential range of applications. The production of high-quality carbon nano-tubes (CNTs) via different precursors has been reported for many years. The arc discharge is a pristine technique to form CNTs with a high-quality yield. This technique has been elucidated for a long time, but the growth condition and mechanism of affected synthesized parameters and coorelation between synthesized parameters and nucleation of carbon have not been explored. In this chapter, the authors present the factors affecting temperature, geometry, grain size, electrodes, pressure, catalyst, arc current, power supply, and growth mechanism of CNTs. The variation in parameters has been elicited along with challenges and gaps.

Synthesis of Carbon Nanotubes Using Plant Source and Study their Properties

In this study the normal and activated charcoal were used to prepare normal and activated multi walled carbon nanotubes (MWCNTs) from same plant (Citrus aurantium) which is a source of carbon by Chemical Flame Deposition method (CFDM). The obtained products were analyzed using FESEM, FTIR, XRD, and Raman spectroscopy. The FESEM image of normal charcoal revealed that it has much less nanopores than activated charcoal. The ratios of ID/IG for the normal and activated MWCNTs were 0.85 and 0.91 respectively, which shows that use activated charcoal as a source enhance the disorder and the defects on the carbon nanotubes. The results demonstrate and confirmed that a carbon nanotubes which were prepared from normal and activated charcoal have some disfigurements and have converging diameter nearly (31-88 nm) and (37-70nm) for normal and activated MWCNTs with length about (1-2) μm respectively.

<p>Artikel ini berisi tentang sintesis <em>carbon nanotubes</em> (CNT) dari material tanaman sebagai upaya untuk mengurangi penggunaan bahan kimia dan pemanfaatan bahan terbarukan. CNT telah berhasil disintesis dari prekursor tanaman seperti cangkang sawit, minyak sawit, bambu, kayu karet, jerami padi, batok kelapa, serat kelapa dan minyak kelapa. Sifat unik dari CNT menyebabkan penelitiannya terus dilakukan dan banyak diterapkan dalam berbagai aplikasi salah satunya material komposit. CNT yang telah disintesis dapat dikompositkan dengan <em>polyaniline</em> (PANI) untuk memperoleh konduktivitas, sifat optik, dan kekuatan mekanik yang lebih unggul. </p><p><strong><em>Review: Synthesis of Carbon Nanotubes (CNT) from Renewable Materials for Carbon Nanotube-Polyaniline Composites. </em></strong>This article contains the synthesis of carbon nanotubes (CNT) from plant materials in an effort to reduce the use of chemicals and the use of renewable materials. CNT has been successfully synthesized from plant precursors such as palm kernel shells, palm oil, bamboo, rubberwood, rice straw, coconut shells, coconut fiber, and coconut oil. The unique properties of CNT have led to continuous research and many applications in various applications, one of which is composite materials. The synthesized CNTs can be composite with polyaniline (PANI) to obtain superior conductivity, optical properties, and mechanical strength.</p>
