Available in PDF, EPUB and Kindle. Book excerpt: This book compiles all current information on the different types of functionalization of carbon nanotubes (CNTs) and graphene, both covalent and non-covalent. The book starts with a general overview of the synthesis, characterization and application of functionalized CNTs and graphene. Special attention is dedicated to the characterization of functionalized materials, a topic rarely addressed on the literature. The authors provide a comparison between the functionalization of these two types of carbon materials.

Available in PDF, EPUB and Kindle. Book excerpt: In an effort to translate the superlative mechanical properties of multiwalled carbon nanotubes (MWCNT) to polymeric media, a novel oligomeric functionalization approach is investigated here. Industrial multiwall carbon nanotubes were subjected first to a gas-phase oxidation process followed by grafting with an amine derivative based on the reaction between diaminodiphenylsulfone (DDS) and triglycidal p-aminophenol (TGAP). By reacting the TGAP with an excess of DDS, a long chain molecule with free amine groups was created that could react with the functionality of the MWCNTs. The synthesized amine derivative oligomer was reactively attached to the MWCNTs via two methods. The first used a diazonium salt reaction scheme whereby isoamyl nitrite was used to convert the aryl amine (AD) to the diazonium salt, which could then couple with the MWCNT through electron donation. The second method used a peptide coupling agent, O-Benzotriazole-N,N,N0́9,N0́9-tetramethyl-uronium-hexafluoro-phosphate (HBTU), to aid in the reaction between the free amine of the DDS:TGAP amine derivative and the carboxylic acid on the nanotube. To determine the effect the oligomer functionalized carbon nanotubes had on a polymeric system, the AD grafted tubes were dispersed into tetraglycidyl methylene dianiline (TGMDA) at 0.5, 1, & 2wt% concentration and cured with DDS. Parallel plate rheometric analysis was then performed on the resulting systems to determine how the functionalized carbon nanotubes affected the rheological properties of the polymer. It was discovered that the functionalized carbon nanotubes had a catalytic effect on the polymer system, accelerating the onset of cure. Furthermore, loss and storage modulus analysis revealed uncommon behavior in the MWCNT enhanced systems, resulting in gel point determination that was not characterized by G0́9 G0́+ crossover. Cured specimens were then tested in oscillating torsion to determine oscillation stress increases over the unmodified polymer with increasing temperature. The greatest increase in oscillation stress over the unmodified TGMDA:DDS polymer, 67%, was recorded at 400℗ʻF by the 0.5wt% HBTU modified TGAP:DDS functionalized MWCNT system. Three point bend testing was then performed on cured specimens to determine the reinforcing properties of the oligomer functionalized carbon nanotubes. Testing revealed that the HBTU:AD functionalized MWCNT at 0.5wt% loading increased average ultimate flexural strength by 77% over the unmodified system .

This book was released on 2017-09-01 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes a series of contemporary techniques and their combinations used for CNTs solubilization, from physical to chemical and biological, applying inorganic and organic compounds, as well as some metal complexes. In some cases, successive steps can be applied, for instance the use of low and high-weight surfactants, or mineral acid treatment for creation of –OH and –COOH groups and their further interaction with organic molecules. Each discussed method leads to an improvement of CNT solubility, frequently a considerable one. The formed dispersions can be stable for long periods of time, from several weeks to some months, and they sometimes even remain stable after centrifugation. Several special studies have been carried out in the areas of influence of solvent and light on CNTs dispersibility, combinations and abilities of surfactants, CNT cytotoxicity, etc. Applications of solubilized CNTs are discussed in this book as well.

This book was released on 2023-02-14 with total page 452 pages. Available in PDF, EPUB and Kindle. Book excerpt: FUNCTIONALIZED CARBON NANOTUBES FOR BIOMEDICAL APPLICATIONS The book highlights established research and technology on current and emerging trends and biomedical applications of functionalized carbon nanotubes by providing academic researchers and scientists in industry, as well as high-tech start-ups, with knowledge of the modern practices that will revolutionize using functionalized carbon nanotubes. Nanotechnology suggests fascinating opportunities for a variety of applications in biomedical fields, including bioimaging and targeted delivery of biomacromolecules into cells. Numerous strategies have been recommended to functionalize carbon nanotubes with raised solubility for efficient use in biomedical applications. Functionalized carbon nanotubes have unique arrangements and extravagant mechanical, thermal, magnetic, optical, electrical, surface, and chemical properties, and the combination of these features gives them widespread biomedical applications. Functionalized carbon nanotubes are relatively flexible and interact with the cell membranes and penetrate different biological tissues owing to a “snaking” effect, therefore both the pharmacological and toxicological profiles of functionalized carbon nanotubes have gathered much attention in recent times. This book covers a broad range of topics relating to carbon nanotubes, from synthesis and functionalization to applications in advanced biomedical devices and systems. As they possess unique and attractive physical, chemical, optical, and even magnetic properties for various applications, considerable effort has been made to employ functionalized carbon nanotubes as new materials for the development of novel biomedical tools, such as diagnostic sensors, imaging agents, and drug/gene delivery systems for both diagnostics and clinical treatment. Audience The book is intended for a very broad audience of researchers and scientists working in the fields of nanomaterials, nanomedicine, bioinspired nanomaterials, nanotechnology, and biomedical application of nanomaterials.

Ralphs and published by . This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Thermal interface materials (TIMs) are used as an aid in transporting heat away from a circuit or electronic module. Composite materials are a popular research area for TIMs because they allow the desired properties from the individual constituents to be combined. The composite selected for this study uses carbon nanotubes (CNT) as the filler and an elastomeric polymer for the matrix, specifically a multiwalled carbon nanotube (MWCNT) / polydimethylsiloxane (PDMS) composite. Additionally, functionalization of the CNT may affect the composites0́9 thermal conductivity because of its effect on the CNT dispersion in the polymer matrix and its effect on the CNT-polymer interface. The objective of this study was to determine the effect CNT functionalization has on the effective thermal conductivity of a MWCNT/PDMS composite. The three functionalization0́9s used in this study are unfunctionalized, functionalized with a carboxyl group, and functionalized with a hydroxyl group. Secondary objectives were to develop the initial stages of a carbon-polymer composite database and to perform an uncertainty analysis on the stepped bar apparatus used in this study. The database is to be used for visualization of data found in literature to promote data driven research. The uncertainty analysis on the stepped bar apparatus is to qualify the instrument for thermal measurements in this study Initial results showed some increase in thermal properties of the composite, but there was little difference between the thermal conductivity of the three functionalization0́9s because of the high level of uncertainty used early on in this study. Later results showed an increase in mechanical properties of the composite which offset any thermal advantage with use as a TIM. A stronger composite means less compression under a similar load, resulting in a thicker TIM and higher resistance. However, the mechanical and thermal properties compound to show that -OH functionalized MWCNT present better properties for a TIM than unfunctionalized and -COOH functionalized; none show better results than the polymer by itself.
