Available in PDF, EPUB and Kindle. Book excerpt: Many organic electronic and bioelectronics devices rely on mixed (electronic and ionic) transport within a single organic layer. Although electronic transport in these materials is relatively well understood, a fundamental understanding of ion transport is missing. I developed a simple analytical model that describes ion transport in a planar junction between an electrolyte and a conducting polymer film. The model leads to predictions of the temporal evolution of drift length of ions and current. These predictions are validated by numerical simulations and by using realistic parameters, I show that the analytical model can be used to obtain the ion mobility in the film. Furthermore, I developed an experimental method which allows the application of the analytical model and leads to a straightforward estimation of the ion drift mobilities in conducting polymers. PEDOT:PSS was found to support efficient transport of common ions, consistent with extensive swelling of the film in water. Crosslinking the film decreased its swelling and the ion mobility. Understanding the high correlation of hydration and ionic conductivity enables us to engineer materials with high and defined ion mobilities. As an example tuning of ion mobility by adjusting the relative ratio of the hydroscopic phase to PEDOT:TOS is presented. Finally I performed electrochemical impedance spectroscopy during a moving front experiment, in order to give a physical interpretation of the impedance spectra at a conducting polymer/electrolyte junction.

Available in PDF, EPUB and Kindle. Book excerpt: An authentic revolution took place in the area of solid-state chemistry and physics just after World War II. The century of solid state started from the modest beginnings of the transistor at Bell Laboratory. Since then, the area of science and technology has been directed primarily toward the study of alloys, ceramics, and inorganic semiconductors. The size of electronic devices became smaller and smaller, while the dimensionality of materials was also reduced just after the invention of the integrated circuit. It is at this point that the advent of the discovery of quasi one-dimensional conductors has opened up a whole new area of ''nonclassical'' solid-state chemistry and physics. In the modern world, plastic and electrical devices are always tightly integrated together. However, it was in 1977 that an electrically conductive, quasi one-dimensional organic polymer, polyacetylene, was discovered. During the past 30 years, a variety of different conducting polymers have been developed. Excitement about these polymeric materials is evidenced by the fact that the field of conducting polymers has attracted scientists from such diverse areas of interest as synthetic chemistry, electrochemistry, solid-state physics, materials science, polymer science, electronics, and electrical engineering.

Available in PDF, EPUB and Kindle. Book excerpt: It is difficult to imagine how our highly evolved technological society would function, or how life would even exist on our planet, if polymers did not exist. The intensive study of polymeric systems, which has been under way for several decades, has recently yielded new insights into the properties of assemblies of these complex molecules and the physical principles that govern their behavior. These developments have included new concepts to describe aspects of the many body behavior in these systems, microscopic analyses that bring our understanding of these systems much closer to our understanding of simple liquids and solids, and the discovery of novel chemistry that these molecules can catalyze. This special topic volume of Advances in Chemical Physics surveys a number of these recent accomplishments. Supplemented with more than 250 illustrations, it provides a significant, up-to-date selection of papers by inter-nationally recognized researchers. Topics include: * Theory of Polyelectrolyte Solutions * Star Polymers: Experiment, Theory, and Simulation * Tethered Polymer Layers * Living Polymers * Transport and Kinetics in Electroactive Polymers Self-contained, authoritative, and timely, Polymeric Systems makes the cutting edge of polymer research available to scientists in every branch of chemical physics.

Download or read book Understanding Ion Transport in Conjugated Polymers written by and published by . This book was released on 2004 with total page 7 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ion transport is critical to improving the performance of conjugated polymer actuators, particularly their strain and speed. We present a novel device that allows us to measure ion transport directly and independently from electron transport in PPy films. The device geometry makes the path for ions much longer than that for electrons, ensuring that ion transport is the rate-limiting step. In addition, ion transport is visualized directly though the change in color of the film (electrochromism) as the electrochemical reaction proceeds, allowing us to precisely and quantitatively track the ion velocity. For high applied voltages, a phase front between oxidized and reduced states is observed to travel into the film, the speed of which is proportional to the applied voltage, which conclusively demonstrates that migration is the key driving force. The phase front broadens with time, which we hypothesize to be due to difflision. At lower applied voltages, there is no phase front, showing that diffusion is the rate-limiting process. A first-cut model that contains diffi%sion and drift terms is postulated, and the simulation results are compared with the experimental data. This simple model predicts the intensity profiles strikingly well.
