Book Description
There is significant interest in new materials exhibiting favourable electronic properties, such as carbon nanotubes and conducting polymers. Particular interest in those two materials stems from the idea that a combination of these two species may give rise to a composite with properties that are superior to the parent components and exhibit synergy in terms of electrical properties. This paper presents results of preliminary experiments to prepare polyaniline/carbon nanotube and polyaniline/carbon nanofibre composites under a variety of reaction conditions. The resulting products are characterized using scanning & transmission electron microscopy and DC conductivity data.

Book Description
Since their discovery in 1977, the evolution of conducting polymers has revolutionized modern science and technology. These polymers enjoy a special status in the area of materials science yet they are not as popular among young readers or common people when compared to other materials like metals, paper, plastics, rubber, textiles, ceramics and composites like concrete. Most importantly, much of the available literature in the form of papers, specific review articles and books is targeted either at advanced readers (scientists / technologists / engineers / senior academicians) or for those who are already familiar with the topic (doctoral / postdoctoral scholars). For a beginner or even school / college students, such compilations are bit difficult to access / digest. In fact, they need proper introduction to the topic of conducting polymers including their discovery, preparation, properties, applications and societal impact, using suitable examples and already known principles/knowledge/phenomenon. Further, active participation of readers in terms of "question & answers", "fill-in-the-blanks", "numerical" along with suitable answer key is necessary to maintain the interest and to initiate the "thought process". The readers also need to know about the drawbacks and any hazards of such materials. Therefore, I believe that a comprehensive source on the science / technology of conducting polymers which maintains a link between grass root fundamentals and state-of-the-art R&D is still missing from the open literature.

Book Description
This volume presents the characterization methods involved with carbon nanotubes and carbon nanotube-based composites, with a more detailed look at computational mechanics approaches, namely the finite element method. Special emphasis is placed on studies that consider the extent to which imperfections in the structure of the nanomaterials affect their mechanical properties. These defects may include random distribution of fibers in the composite structure, as well as atom vacancies, perturbation and doping in the structure of individual carbon nanotubes.

Book Description
This book shows the recent advances of the applications of carbon nanotubes (CNTs), in particular, the polymer functionalized carbon nanotubes. It also includes a comprehensive description of carbon nanotubes' preparation, properties, and characterization. Therefore, we have attempted to provide detailed information about the polymer-carbon nanotube composites. With regard to the unique structure and properties of carbon nanotubes, a series of important findings have been reported. The unique properties of carbon nanotubes, including thermal, mechanical, and electrical properties, after polymer functionalization have been documented in detail. This book comprises 18 chapters. The chapters include different applications of polymer functionalization CNTs, e.g. photovoltaic, biomedical, drug delivery, gene delivery, stem cell therapy, thermal therapy, biological detection and imaging, electroanalytical, energy, supercapacitor, and gas sensor applications.

Book Description
The use of nanotechnologies continues to grow, as nanomaterials have proven their versatility and use in many different fields and industries within the scientific profession. Using nanotechnology, materials can be made lighter, more durable, more reactive, and more efficient leading nanoscale materials to enhance many everyday products and processes. With many different sizes, shapes, and internal structures, the applications are endless. These uses range from pharmaceutics to materials such as cement or cloth, electronics, environmental sustainability, and more. Therefore, there has been a recent surge of research focused on the synthesis and characterizations of these nanomaterials to better understand how they can be used, their applications, and the many different types. The Research Anthology on Synthesis, Characterization, and Applications of Nanomaterials seeks to address not only how nanomaterials are created, used, or characterized, but also to apply this knowledge to the multidimensional industries, fields, and applications of nanomaterials and nanoscience. This includes topics such as both natural and manmade nanomaterials; the size, shape, reactivity, and other essential characteristics of nanomaterials; challenges and potential effects of using nanomaterials; and the advantages of nanomaterials with multidisciplinary uses. This book is ideally designed for researchers, engineers, practitioners, industrialists, educators, strategists, policymakers, scientists, and students working in fields that include materials engineering, engineering science, nanotechnology, biotechnology, microbiology, drug design and delivery, medicine, and more.

Book Description
New hybrid materials from the grafting of polystyrene on the surface of nitrogen doped carbon nanotube were synthesized. These chemically modified nanotubes were further used in the fabrication of polymer based nanocomposites. In these works, we studied the impact of the polymer grafted nanotubes on the electrical and mechanical properties of a polystyrene (PS) and a poly (butadiene-co-styrene) (PSBS) matrices. The grafted nanotubes have a better dispersion in a PS matrix as compared to the as received ones. Nevertheless, this kind of functionalization does not lower the percolation threshold since the grafted polymer layer electrically isolates the nanotubes each others. On the other hand, the mechanical reinforcement (PS matrix) increases when the nanotubes are polymer grafted. Furthermore, a stronger mechanical reinforcement is observed for large strain deformation. Concerning the nano-structured PSBS matrix, we observed a stronger mechanical reinforcement as compared to the PS matrix. The PS grafted nanotubes permit to connect the PS nano-domains of the matrix and consequently forms a percolating rigid network with a very low threshold (PC
