Download or read book Fundamentals of Conjugated Polymer Blends Copolymers and Composites written by Parveen Saini and published by John Wiley & Sons. This book was released on 2015-04-30 with total page 684 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Carbon Nanotubes written by Siva Yellampalli and published by BoD – Books on Demand. This book was released on 2011-08-17 with total page 414 pages. Available in PDF, EPUB and Kindle. Book excerpt: Polymer nanocomposites are a class of material with a great deal of promise for potential applications in various industries ranging from construction to aerospace. The main difference between polymeric nanocomposites and conventional composites is the filler that is being used for reinforcement. In the nanocomposites the reinforcement is on the order of nanometer that leads to a very different final macroscopic property. Due to this unique feature polymeric nanocomposites have been studied exclusively in the last decade using various nanofillers such as minerals, sheets or fibers. This books focuses on the preparation and property analysis of polymer nanocomposites with CNTs (fibers) as nano fillers. The book has been divided into three sections. The first section deals with fabrication and property analysis of new carbon nanotube structures. The second section deals with preparation and characterization of polymer composites with CNTs followed by the various applications of polymers with CNTs in the third section.
Download or read book Synthesis and Characterization of Polymer carbon Nanotubes Composites written by Benjamin Fragneaud and published by . This book was released on 2006 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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
