Book excerpt: A fiber of carbon nanotubes was prepared by a wet-spinning method involving drawing carbon nanotubes away from a substantially aligned, supported array of carbon nanotubes to form a ribbon, wetting the ribbon with a liquid, and spinning a fiber from the wetted ribbon. The liquid can be a polymer solution and after forming the fiber, the polymer can be cured. The resulting fiber has a higher tensile strength and higher conductivity compared to dry-spun fibers and to wet-spun fibers prepared by other methods.

This book was released on 2011 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: Carbon nanotubes have exciting potential to provide high performance materials of the future. One of the main challenges is assembling the billions of miles of individual nanotubes in each pound of product nanotube fiber or sheet in such a way that the properties of the individual nanotubes are most effectively utilized. In this study a novel wet fiber spinning method was developed in which carbon nanotubes dispersed in a surfactant are injected into a rotating acid bath which coagulates the dispersion to form a macroscopic fiber. This flocculation method produces highly conducting carbon nanotube fibers and sheets without the need for a polymer binder. The mechanical strength is sufficient for several applications and can be improved by either heat treatment or by incorporation of a polymer in the yarn, and subsequent draw. Poly(Vinyl Alcohol) (PVA)-treated fibers yield outstanding mechanical properties and a toughness that is comparable to spider silk. Other polymers, such as polyvinylpyrrolidone (PVP) also enhance mechanical properties. Inorganic additives, such as platinum, can be incorporated into the fiber matrix to provide multifunctionality.

Download or read book Spinning Methods for Carbon Nanotube Fibers written by Anli Wang and published by . This book was released on 2014 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: Carbon nanotubes (CNTs) have excellent properties along the tube axis. Although the material has fantastic properties at nano scale, it has proven difficult to assemble CNTs into macro-scale products that retain these properties. This thesis investigates different methods for spinning short CNTs into continuous fibers. The first part of the thesis concentrates on the study of dry spinning techniques. CNT fibers can be produced from spinnable arrays. It is found that CNT length plays an important role in the strength of CNT fibers. However, long CNT arrays are usually not spinnable. Alternative ways to spin long CNTs into fibers were exploited. One way is to assemble these long CNTs with the aid of liquid. The obtained fiber has high electrical conductivity by using annealed CNTs but low strength. Another way explored is to make a long CNT array spinnable by binding the ends of CNT bundles in the array. Besides dry spinning, wet spinning methods were also applied to spin CNT fibers. One way of wet spinning to produce CNT fibers is through coagulation of CNT dispersions in a polymer bath. Parameters involved in the spinning process and post treatments were studied. A possible mechanism of the coagulation was given. Process of another method is to add CNTs in a polymer solution and wet spin the polymer. Polyvinyl alcohol (PVA) is used as the matrix polymer and several baths were investigated. Addition of CNTs in PVA solution improves strength of the fiber when CNT are well dispersed. Properties of these fibers were dominated by the polymer.

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.
