1. Microphase Separated Cation Conducting Polymers : Design, Synthesis, and Properties
Sammanfattning : This thesis describes the synthesis and properties of five different cation conducting polymer systems. These systems were designed so that the polymers would be able to microphase separate into distinct phases with one phase for mechanical strength and one for ionic conductivity. LÄS MER
2. Electrolyte : Semiconductor Combinations for Organic Electronic Devices
Sammanfattning : The discovery of semi-conducting organic materials has opened new possibilities for electronic devices and systems because of their solution processibility, lightweight and flexibility compared to inorganic semiconductors. The combination of semiconductors with electrolytes, and more especially organic semiconductors and solid electrolytes has attracted the attention of researchers because of the multiple phenomena originating from the simultaneous motion of electrons and ions.

3. Electrolyte-Gated Organic Thin-Film Transistors
Sammanfattning : There has been a remarkable progress in the development of organic electronic materials since the discovery of conducting polymers more than three decades ago. Many of these materials can be processed from solution, in the form as inks. LÄS MER
4. Novel Materials for Fuel Cells and Batteries Light Scattering Studies of the Structure and Dynamics of Polymer Electrolytes
Sammanfattning : The development of new materials and technologies for electrochemical energy conversion and storage, such as fuel cells and batteries, is important for a future more efficient use of energy. Polymer electrolytes are key components in polymer electrolyte fuel cells and lithium-based batteries. LÄS MER
5. Evaluating Cathode Catalysts in the Polymer Electrolyte Fuel Cell
Sammanfattning : The polymer electrolyte membrane fuel cell (PEMFC) converts the chemical energy of hydrogen and oxygen (air) into usable electrical energy. At the cathode (the positive electrode), a considerable amount of platinum is generally required to catalyse the sluggish oxygen reduction reaction (ORR). LÄS MER
