Doping In Conjugated Polymers

eBook Download

BOOK EXCERPT:

An A-to-Z of doping including its definition, its importance, methods of measurement, advantages and disadvantages, properties and characteristics—and role in conjugated polymers The versatility of polymer materials is expanding because of the introduction of electro-active behavior into the characteristics of some of them. The most exciting development in this area is related to the discovery of intrinsically conductive polymers or conjugated polymers, which include such examples as polyacetylene, polyaniline, polypyrrole, and polythiophene as well as their derivatives. "Synmet" or "synthetic metal" conjugated polymers, with their metallic characteristics, including conductivity, are of special interest to researchers. An area of limitless potential and application, conjugated polymers have sparked enormous interest, beginning in 2000 when the Nobel Prize for the discovery and development of electrically conducting conjugated polymers was awarded to three scientists: Alan J. Heeger, Alan G. MacDiarmid, and Hideki Shirakawa. Conjugated polymers have a combination of properties—both metallic (conductivity) and polymeric; doping gives the conjugated polymer's semiconducting a wide range of conductivity, from insulating to low conducting. The doping process is a tested effective method for producing conducting polymers as semiconducting material, providing a substitute for inorganic semiconductors. Doping in Conjugated Polymers is the first book dedicated to the subject and offers a comprehensive A-to-Z overview. It details doping interaction, dopant types, doping techniques, and the influence of the dopant on applications. It explains how the performance of doped conjugated polymers is greatly influenced by the nature of the dopants and their level of distribution within the polymer, and shows how the electrochemical, mechanical, and optical properties of the doped conjugated polymers can be tailored by controlling the size and mobility of the dopants counter ions. The book also examines doping at the nanoscale, in particular, with carbon nanotubes. Readership The book will interest a broad range of researchers including chemists, electrochemists, biochemists, experimental and theoretical physicists, electronic and electrical engineers, polymer and materials scientists. It can also be used in both graduate and upper-level undergraduate courses on conjugated polymers and polymer technology.

Conjugated Polymers Synthesis Design

eBook Download

BOOK EXCERPT:

This digital primer serves as an excellent introduction to conjugated polymers, particularly in terms of their synthesis and design. Chapters one and two introduce common terminology and fundamental concepts. Chapter three covers known structure–function relationships that can be used to design conjugated polymers with the desired properties for specific applications, concluding with a discussion of the additive and sometimes conflicting aspects of these design elements. Chapters four, five, and six cover the various methods used to synthesize these materials, beginning with the oldest and most simple approaches, and increasing in synthetic complexity. Advanced undergraduates, graduate students, and faculty wishing to enter this field for the first time should find this primer beneficial. At the same time, however, we have pointed out various misconceptions still commonly found in the literature, which should be valuable to those already familiar with these materials.

Nanofibers Of Conjugated Polymers

eBook Download

BOOK EXCERPT:

Conjugated polymer composites with high dielectric constants are being developed by the electronics industry in response to the need for power-grounded decoupling to secure the integrity of high-speed signals and to reduce electromagnetic interference. Electrically conducting polymers are materials that simultaneously possess the physical and chemical properties of organic polymers and the electronic characteristics of metals. Multifunctional micro- and nanostructures of conjugated polymers, such as of pyrrole, have received great attention in recent years because they can polymerize easily and have high conductivity and good thermal stability. They, however, have some disadvantages such as brittleness and hard processability, which can be overcome by developing their nanocomposites. Nanofiber materials with different dielectric properties can be made from conjugated polymer composites and used in the electronics industry, in sensors and batteries, for electrical stimulation to enhance nerve-regeneration process, and for constructing scaffolds for nerve tissue engineering. Electrospinning is a versatile technique that is used to produce ultrathin continuous fibers with high surface-to-volume and aspect ratios from a variety of materials, including polymers, composites, and ceramics. Conductive materials in fibrillar shape may be advantageous compared with films because of their inherent properties such as anisotropy, high surface area, and mechanical strength. They are of particular interest in electroactive composites as they can be efficiently distributed in an insulating polymer matrix to improve both electrical and mechanical properties. Combination of electrical properties with good mechanical performance is of particular interest in electroactive polymer technology. This book covers the general aspects of electrospinning and discusses the fundamental concepts that can be used to produce nanofibers with the help of mathematical models and equations. It also details the methods through which different polymeric structures can be included in conjugated polymers during electrospinning to form composites or blends of conjugated polymer nanofibers.

Fundamentals Of Conjugated Polymer Blends Copolymers And Composites

eBook Download

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.
