  2. 21. Electrochromic Properties of Iridium Oxide Based Thin Films

    Author : Jonas Backholm; Gunnar A. Niklasson; Andris Azens; Franco Decker; Uppsala universitet; []
    Keywords : Engineering physics; Electrochromism; iridium oxide; hydrogen intercalation; chemical diffusion coefficient; density of states; optical modulation; Teknisk fysik;

    Abstract : Electrochromic iridium oxide (IrOx) and iridium-tantalum oxide (IrTaOx) thin films were prepared by reactive magnetron sputtering. Composition, density, and structure were determined using Rutherford backscattering spectroscopy, X-ray photoelectron spectroscopy, X-ray diffraction, scanning electron microscopy, transmission electron microscopy, and electron energy loss spectroscopy.

  4. 22. Flexible and Cellulose-based Organic Electronics

    Author : Jesper Edberg; Magnus Berggren; Isak Engquist; Leif Nyholm; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Organic electronics; conductive polymers; nanocellulose; nanofibrillated cellulose; composite materials; paper electronics; flexible electronics;

    Abstract : Organic electronics is the study of organic materials with electronic functionality and the applications of such materials. In the 1970s, the discovery that polymers can be made electrically conductive led to an explosion within this field which has continued to grow year by year. READ MORE

  5. 23. All-Thin-Film Electrochromic Devices for Optical and Thermal Modulation

    Author : Anna-Lena Larsson; Gunnar A Niklasson; Lars Stenmark; Michael G Hutchins; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering physics; Teknisk fysik; Engineering physics; Teknisk fysik;

    Abstract : The optical properties of electrochromic materials can be changed by application of an electrical voltage. The conventional electrochromic device consists of several thin films of electrochromic materials and layers for electron- and ion conduction. READ MORE

  6. 24. Lithium Ion Conductive Membranes Based on Co-continuous Polymer Blends

    Author : Anette Munch Elmér; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Polymerteknik; Polymer technology; biopolymers; conductivity measurements; in-situ UV-polymerisation; solution casting; poly methyl methacrylate ; vinylidene fluoride copolymers; poly ethylene carbonate-co-ethylene oxide methacrylate; PEG methacrylate macromonomers; heterogeneous polymer blends; polymer electrolyte membranes; lithium salt containing gels;

    Abstract : There is a growing need for multifunctional polymeric materials for the development of several important energy conversion technologies. For example, the polymer electrolyte is a key component in lithium polymer batteries. The basic functions of this electrolyte are to efficiently conduct the lithium ions and physically separate the electrodes. READ MORE

  7. 25. Electrolyte-Based Organic Electronic Devices

    Author : Elias Said; Magnus Berggren; Robert Forchheimer; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Conjugated polymers; Electrolytes; Organic Field Effect Transistors; Physics; Fysik;

    Abstract : The discovery of semi-conducting and conducting organic materials has opened new possibilities for electronic devices and systems. Applications, previously unattainable for conventional electronics, have become possible thanks to the development of conjugated polymers. READ MORE
