This book was released on 2017 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: Conjugated polymers such as poly(3,4-ethylenedioxythiophene) (PEDOT) are of interest for a variety of applications including interfaces between electronic biomedical devices and living tissue. These polymers provide an improved interface compared to metal and semiconducting electrodes because of their ionic conductivity, relatively lower stiffness, and ability to incorporate biological molecules. Even though the signal transfer and biocompatibility of conjugated polymers are superior as the biointerfacing materials, the durability has been the weakest part for the long-term applications. Some efforts have been made to improve the durability of conjugated polymers, however, little quantitative information of the improved cohesion, adhesion and durability has been reported. ☐ In this thesis, the methods of improving the durability of conjugated polymer films, especially PEDOT, were investigated, including alternating the processing methods and components in synthesis. The 7-month in vivo testing showed a superior neural signal recording performance, however the durability of PEDOT films still needed to be improved. ☐ As a coating for biosignal transfer, the cohesion, adhesion and electrochemical stability of PEDOT are vital to determine the long-term performance. By far, not much information of cohesion and adhesion of conjugated polymer coatings has been dug out. In this thesis, a thin film cracking method was developed to measure the stiffness, strength and the interfacial shear strength (adhesion) of electrochemically deposited PEDOT. The estimated Young’s modulus of the PEDOT films was 2.6 ± 1.4 GPa, and the strain to failure was around 2%. The tensile strength was measured to be 56 ± 27 MPa. The effectiveness of crosslinker and adhesion promoter was demonstrated by this method. It was shown that 5 mole% addition of a tri-functional EDOT crosslinker increased the tensile strength of the films to 283 ± 67 MPa, while the strain to failure remained about the same (2%). With the modification of EDOTacid to the surface of stainless steel substrate, the interfacial shear strength was improved from 11.8 MPa to 32.5 MPa. ☐ To correlate the adhesion with the durability of PEDOT coatings, a tribology test was introduced. It was found that the durability of PEDOT on Au electrode was exceptionally good, and even better than the adhesion promoted coatings with EDOTacid on stainless steel and ITO substrates. The characterization method developed in this thesis made a critical difference in systematically comparing different materials, and provided valuable information for materials development and selection.

Book excerpt: The pioneering work by Nobel Prize Laureates Heeger, MacDiarmid, and Shirakawa marked the birth of conductive polymers, a new family of revolutionary organic materials at the boundaries between classic plastics, metals, and semiconductors. Since then, a host of chemically diverse conducting polymeric structures has been devised with fascinating optical, electrical, magnetic, and redox properties that can be tuned using easy chemical/electrochemical doping. In recent decades, the combination and blend of conductive polymers with other materials families (e.g., carbon nanomaterials, metal nanoparticles or oxide nanostructures, common polymers, and resins) fostered the advent of a new generation of hybrid multifunctional composites with enhanced properties and high potential for present and near-future everyday life applications, ranging from photovoltaics, OLEDs, smart windows and garments, plastic batteries for sensors, and intelligent actuators. In this book, we compile some of the latest advances in the field, covering both old issues and new examples emphasizing emerging applications in biomedical science, healthcare, separation science, and water pollution abatement.

Book excerpt: Conducting polymers are organic, conjugated materials that offer high electrical conductivity through doping by oxidation and a wide range of unique electromechanical and electrochromic characteristics. These properties can be reversibly tuned through electrochemical reactions, making this class of materials good biomimetic models and ideal candidates for the development of novel flexible and transparent sensing devices. This book comprehensively summarises the current and future applications of conducting polymers, with chapters focussing on electrosynthesis strategies, theoretical models for composition dependent allosteric and structural changes, composition dependent biomimetic properties, novel biomimetic devices and future developments of zoomorphic and anthropomorphic tools. Written by an expert researcher working within the field, this title will have broad appeal to materials scientists in industry and academia, from postgraduate level upwards.

This book was released on 1993-05-31 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electroactive polymers have been the object of increasing academic and industrial interest and in the past ten to fifteen years substantial progress has been achieved in the development and the characterization of this important new class of conducting materials. These materials are usually classified in two large groups, according to the mode of their electric transport. One group includes polymers having transport almost exclusively of the ionic type and they are often called 'polymer electrolytes' or, in a broader way, 'polymer ionics'. The other group includes polymeric materials where the transport mechanism is mainly electronic in nature and which are commonly termed 'conducting polymers'. Ionically conducting polymers or polymer ionics may be typically described as polar macromolecular solids in which one or more of a wide range of salts has been dissolved. The most classic example is the combina tion of poly(ethylene oxide), PEO, and lithium salts, LiX. These PEO-LiX polymer ionics were first described and proposed for applications just over ten years ago. The practical relevance of these new materials was im mediately recognized and in the course of a few years the field expanded tremendously with the involvement of many academic and industrial lab oratories. Following this diversified research activity, the ionic transport mechanism in polymer ionics was soon established and this has led to the development of new host polymers of various types, new salts and advanced polymer architectures which have enabled room temperature conductivity to be raised by several orders of magnitude.

This book was released on 2013-04-17 with total page 233 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains the majority of the papers presented at the NATO Ad vanced Research Workshop (ARW) held in Burlington, Vermont, USA on October 12-15, 1992. This ARW was the first of its kind to address the subject of intrinsically conducting polymers with an emphasis on processing and technological applications. The NATO ARW format was followed in that the subjects addressed here were limited in number but discussed in detail with the attendance being limited to a small number of selected scientists. The ARW brought together lecturers who are leaders in their respective fields from a wide range of NATO and non-NATO countries (a total of 11 countries) with the support of the NATO Scientific Affairs Division and some support from Champlain Cable Corporation. The total number of par ticipants was 33 and the number of presentations was 24. The speakers were chosen based on the topics selected for this workshop and repre sented industry, universities and government laboratories. The field of conducting polymers has grown rapidly during the past few years with important developments in materials processing and fabrica tion that brought about active research programs focusing on the use of these polymers as "smart" materials in technological applications and devices in academic and industrial research laboratories.
