Book Description
The excellent electrical, mechanical and thermal properties along with the high specific surface area of carbon nanotubes make them a strong candidate as functional fillers for polymer matrices in view of developing a multifunctional light-weight composite. However, the significant challenge in achieving a good dispersion of these nanotubes in the host polymer due to their inert chemical surface and tendency to exist as agglomerates inhibits their theoretical potential. Thermoplastic polymers, specifically olefins present a complex scenario for achieving good carbon nanotube dispersion owing to their high melt viscosity and incompatible surface energies with carbon nanotubes. Process parameter optimization and the usage of an economical reactive processing additive lead to an extremely good carbon nanotube dispersion in polypropylene, and consequently result in excellent electrical and thermal properties of the composite at very low filler loadings. Incorporation of glass fibers as secondary fillers lead to a substantial improvement in the mechanical properties of the bi-filler composite whilst preserving the enhancements in electrical and thermal properties caused by carbon nanotube addition. This led to a multifunctional composite with excellent electrical, structural and thermal properties with significant potential for light-weight product development.

Book Description
From the Foreword, written by legendary nano pioneer M. Meyyappan, Chief Scientist for Exploration Technology NASA Ames Research Center, Moffett Field, California, USA: "...there is critical need for a book to summarize the status of the field but more importantly to lay out the principles behind the technology. This is what Professor Arvind Agarwal and his co-workers ... have done here." Carbon Nanotubes: Reinforced Metal Matrix Composites reflects the authors’ desire to share the benefits of nanotechnology with the masses by developing metal matrix carbon nanotube (MM-CNT) composites for large-scale applications. Multiwall carbon nanotubes can now be produced on a large scale and at a significantly reduced cost. The book explores potential applications and applies the author’s own research to highlight critical developmental issues for different MM-CNT composites—and then outline novel solutions. With this problem-solving approach, the book explores: Advantages, limitations, and the evolution of processing techniques used for MM-CNT composites Characterization techniques unique to the study of MM-CNT composites—and the limitations of these methods Existing research on different MM-CNT composites, presented in useful tables that include composition, processing method, quality of CNT dispersion, and properties The micro-mechanical strengthening that results from adding CNT The applicability of micro-mechanics models in MM-CNT composites Significance of chemical stability for carbon nanotubes in the metal matrix as a function of processing, and its impact on CNT/metal interface and mechanical properties Computational studies that have not been sufficiently covered although they are essential to research and development The critical issue of CNT dispersion in the metal matrix, as well as a unique way to quantify CNT distribution and subsequently improve control of the processing parameters for obtaining improved properties Carbon Nanotubes: Reinforced Metal Matrix Composites paints a vivid picture of scientific and application achievements in this field. Exploring the mechanisms through which CNTs are enhancing the properties of different metal-based composites, the authors provide a roadmap to help researchers develop MM-CNT composites and choose potential materials for use in emerging areas of technology.

Book Description
Carbon Nanotube-Reinforced Polymers: From Nanoscale to Macroscale addresses the advances in nanotechnology that have led to the development of a new class of composite materials known as CNT-reinforced polymers. The low density and high aspect ratio, together with their exceptional mechanical, electrical and thermal properties, render carbon nanotubes as a good reinforcing agent for composites. In addition, these simulation and modeling techniques play a significant role in characterizing their properties and understanding their mechanical behavior, and are thus discussed and demonstrated in this comprehensive book that presents the state-of-the-art research in the field of modeling, characterization and processing. The book separates the theoretical studies on the mechanical properties of CNTs and their composites into atomistic modeling and continuum mechanics-based approaches, including both analytical and numerical ones, along with multi-scale modeling techniques. Different efforts have been done in this field to address the mechanical behavior of isolated CNTs and their composites by numerous researchers, signaling that this area of study is ongoing. Explains modeling approaches to carbon nanotubes, together with their application, strengths and limitations Outlines the properties of different carbon nanotube-based composites, exploring how they are used in the mechanical and structural components Analyzes the behavior of carbon nanotube-based composites in different conditions

Book Description
The well documented increase in the use of high performance composites as structural materials in aerospace components is continuously raising the demands in terms of dynamic performance, structural integrity, reliable life monitoring systems and adaptive actuating abilities. Current technologies address the above issues separately; material property tailoring and custom design practices aim to the enhancement of dynamic and damage tolerance characteristics, whereas life monitoring and actuation is performed with embedded sensors that may be detrimental to the structural integrity of the component. This publication explores the unique properties of carbon nanotubes (CNT) as an additive in the matrix of Fibre Reinforced Plastics (FRP), for producing structural composites with improved mechanical performance as well as sensing/actuating capabilities. The successful combination of the CNT properties and existing sensing actuating technologies leads to the realization of a multifunctional FRP structure. The current volume presents the state of the art research in this field. The contributions cover all the aspects of the novel composite systems, i.e. modeling from nano to macro scale, enhancement of structural efficiency, dispersion and manufacturing, integral health monitoring abilities, Raman monitoring, as well as the capabilities that ordered carbon nanotube arrays offer in terms of sensing and/or actuating in aerospace composites.

Book Description
Owing to their remarkable properties, carbon nanotubes (CNTs) hold a huge potential as fillers in the production of multifunctional composites for many applications. However, their tendency to agglomerate as well as their chemically inert surface makes the task of dispersion very challenging. In spite of the immense effort aimed at understanding CNT dispersions and its implication for the properties of nanocomposites and suspensions, very little progress has thus far been made in terms of correlating the microstructural morphology of nanocomposites to their properties. By measuring the extend of interfacial polarization in CNT/epoxy suspensions subjected to oscillatory shear flow in a rheometer, a novel measurement strategy for assessing the dispersion evolution of CNTs, during shear mixing in an epoxy resin with a three-roll mill, has been developed in this study. This allowed the influence of applied shear intensity, compatibility between CNT and matrix, initial CNT agglomerate morphology, as well as matrix viscosity on CNT dispersion quality during shear mixing to be investigated.
