Abstract:

This thesis focuses on two of the major challenges of carbon nanotube (CNT) research: understanding the growth mechanism of nanotubes by chemical vapour deposition (CVD) and the positioning of nanotubes on surfaces. The mechanism of growth of single–walled nanotubes (SWNTs) has been studied in two ways. Firstly, a novel iron nanoparticle catalyst for the production of single–walled nanotubes was developed. CVD conditions were established that produced high quality tubes. These optimised CVD conditions were then used as the basis of several comparative CVD experiments showing that the quality o

Abstract:

The use of single-walled carbon nanotubes (SWNTs) as test tubes for the encapsulation of metallic nanoparticles (MNPs) and the formation of inorganic nanomaterials has been advanced. A methodology to encapsulate the group 10 and 11 metals inside SWNTs to investigate their properties has been optimised. Each metal interacts with carbon differently at the atomic level, as shown by aberration-corrected high resolution transmission electron microscopy (AC-HRTEM), leading to the promotion of a plethora of different processes stimulated by MNPs under the electron beam. Additionally, interactions bet

An industrial application of CNT requires the understanding of the growth mechanism and the control of the synthesis process parameters.

Portland cement (PC) is one of the most consumed products of the world.

Carbon nanotubes have exceptionally high tensile strength and are therefore candidates for structural reinforcement of cement materials. Many tentative have been reported to develop composites with the physical mixture of high quality nanotubes and cement. These processes today are still unviable for large scale production of construction material. The problems are linked to the scale and costs

Recently the development of efficient methodologies for covalent chemical modification has raised hope for the use of these materials in various fields of application such as biosensors, vaccine and drug delivery systems, medical imaging, biomaterials, water purification,

Abstract:

Carbon nanotubes (CNTs) are advanced materials that have numerous novel and useful properties. Controlling the synthesis and properties of CNTs is the major challenge toward their future applications. This thesis addresses this challenge with several contributions. This thesis begins with the brief introduction of CNTs, including the history of their discovery, their geometric structure, unique properties and potential applications. Then focus is laid on the subsequent three sections: characterization, synthesis, and manipulation of CNTs. Chapter 2 describes three characterization tools: AF

Abstract:

The chemistry and applications of carbon nanotubes are critically dependent on nanotube chirality. To date, no one has demonstrated chirality-selective synthesis of single-walled carbon nanotubes from pre-synthesized catalyst nanoparticles. A proposed chemical approach to the mass production of chirality-selective SWNTs is their "cloning" by chemical cutting, decoration with catalyst nanoparticles, and continued growth. The progress of this process will be reviewed. Purified HiPco nanotubes were sidewall functionalized to allow suspension in water and organic solvents. Methods were developed t

Abstract:

碩士<br>國立臺北科技大學<br>製造科技研究所<br>89<br>This thesis is mainly focused on the synthesis and field emission property applications of carbon nanotubes (CNTs). A two-step process was employed to synthesize CNTs in that ion beam sputtering deposition (IBSD) was used to deposit iron or nickel catalyst thin films on silicon and Corning glass 7059 followed by hydrogen plasma pretreatment to form nano-size Fe or Ni particles and the CNTs growth by microwave plasma-enhanced chemical vapor deposition (MPECVD) at the second step. Well-aligned, uniform carbon nanotubes (CNTs) have been obtained in la
