Book excerpt: Carbon nanotubes have hundreds of potential applications but require innovative processing techniques to manipulate the microscopic carbon dust into useful devices and products. This thesis describes efforts to process carbon nanotubes (CNTs) using novel methods with the goals of: 1) improving the properties of energy absorbing and composite carbon nanotube materials and 2) increasing understanding of fundamental structure â€" property relationships within these materials. Millimeter long CNTs, in the form of arrays, yarns and papers, were used to produce energy absorbing foams and high volume fraction CNT composites. Vertically aligned CNT arrays were grown on silicon substrates using chemical vapor deposition (CVD) of ethylene gas over iron nano-particles. The low density, millimeter thick arrays were tested under compression as energy absorbing foams. With additional CVD processing steps, it was possible to tune the compressive properties of the arrays. After the longest treatment, the compressive strength of the arrays was increased by a factor of 35 with a density increase of only six fold, while also imparting recovery from compression to the array. Microscopy revealed that the post-synthesis CVD treatment increased the number of CNT walls through an epitaxial type radial growth on the surface of the as-grown tubes. The increase in tube radius and mutual support between nanotubes explained the increases in compressive strength while an increase in nanotube roughness was proposed as the morphological change responsible for recovery in the array. Carbon nanotube yarns were used as the raw material for macroscopic textile preforms with a multi-level hierarchical carbon nanotube (CNT) structure: nanotubes, bundles, spun single yarns, plied yarns and 3-D braids. In prior tensile tests, composites produced from the 3-D braids exhibited unusual mechanical behavior effects. The proposed physical hypotheses explained those effects by molecular level interactions and mo.

Available in PDF, EPUB and Kindle. Book excerpt: Ultralong multiwalled carbon nanotube arrays (forests) were grown by chloride-mediated chemical vapor deposition, in which iron chloride was used as a catalyst precursor. Highly spinnable millimeter-long arrays were grown with a very rapid growth rate of 100 μm/min. By stacking long-lasting carbon nanotube (CNT) webs, unidirectionally aligned CNT sheets were fabricated. The sheet was highly anisotropic in electrical and thermal properties and due to high alignment of the CNTs in the sheets. CNT yarns were fabricated using the millimeter-long CNTs and a detailed analysis of various postspin processes, including postspin twisting and multiply twisting, and their effect on CNT yarns were studied. Mechanical properties clearly depended on the dimensions of CNTs, where thinner and longer CNTs led to strong and stiff yarns. Large contacting surface areas in the yarns, brought by closer packing with high-aspect-ratio CNTs, were effective for higher van der Waals interaction leading to higher tensile properties. Growth of millimeter-long highly spinnable CNT arrays and the material properties of tailored large-scale CNT structures, including unidirectionally aligned sheets and spun yarns, are described.

Available in PDF, EPUB and Kindle. Book excerpt: Carbon nanotube (CNT) yarn, a macroscopic structure of CNTs with many potential applications, has attracted increased attention around the world and across many research areas and industrial fields, including materials science, electronics, medical biology and ecology. Spinning CNTs into yarn based on traditional textile spinning principles has demonstrated the potential in many important applications by producing weavable multifunctionalized yarns. Between 1991 and 2010, new manufacturing methods have enabled the production of pure CNT yarns and CNT-based composite yarns called superfiber suitable for weaving, knitting and braiding with continuous improvements. Especially various novel technologies are used to recently produce yarns for electrochemical devices and medical bioengineering. Thus, the studies on assembling individual CNTs into macrostructures of controlled and oriented configurations continue to play an important role in exploiting CNT potential applications.

Available in PDF, EPUB and Kindle. Book excerpt: Individual carbon nanotubes (CNTs) have exceptional mechanical and electrical properties. However, the transfer of these extraordinary qualities into CNT products, without compromising performance, remains a challenge. This chapter presents an overview of the manufacturing of CNT sheets and buckypaper and also describes research performed at the University of Cincinnati in this field. CNT arrays were grown using the chemical vapor deposition method. Sheets were drawn from the spinnable CNT arrays and characterized using scanning electron microscopy to show the highly unidirectional alignment of the nanotubes in the sheet. The anisotropic morphology of the sheet provides superior properties along one material axis as observed by measuring the tensile strength, electrical resistivity, optical transmittance, and electromagnetic interference shielding properties of the material. Surface modification of aligned multiwall nanotube sheets was carried out via incorporation of an atmospheric pressure plasma jet in the sheet posttreatment process. Helium/oxygen plasma was utilized to produce carboxyl (–COO−) functionality on the surface of the nanotubes. X-ray photoelectron spectroscopy confirmed the presence of the functional groups on the nanotube surface. The sheet was further characterized using Raman spectroscopy, Fourier transform infrared spectroscopy, and contact angle testing. Composite laminates made from functionalized CNT sheets showed higher strength than those made with pristine sheets. The effects of plasma power and oxygen concentration were studied in order to determine the best possible parameters for functionalization. Plasma treatment is a useful tool for fast, clean and dry functionalization of CNTs. This study demonstrates the ease of incorporating the plasma tool in the manufacturing process of sheets leading to the production of CNT/polymer composites. Macroscopic structures of nanotubes such as threads and sheets are leading to novel applications.

Available in PDF, EPUB and Kindle. Book excerpt: Since the discovery of graphene, it has become one of the most widely and extensively studied materials. This book aims to summarize the progress in synthesis, processing, characterization and applications of a special group of nanocarbon materials derived from graphene or graphene related derivatives by using various strategies in different forms. More specifically, three forms of macrosized materials are presented, i.e., one-dimension or 1D (fibers, wires, yarns, streads, etc.), two-dimension or 2D (films, membranes, papers, sheets, etc.) and three-dimension or 3D (bulk, hydrogels, aerogels, foams, sponges, etc.). Seven chapters are included with the first chapter serving to introduce the concept, definition, and nomenclature of graphene, graphene oxide and their derivatives. The main topics are covered in Chapters 2‒7. Although they have coherent connections, each chapter of them is designed such that they can be studied independently. The target readers of this book include undergraduate students, postgraduate students, researchers, designers, engineers, professors, and program/project managers from the fields of materials science and engineering, applied physics, chemical engineering, biomaterials, materials manufacturing and design, institutes, and research founding agencies.
