  2. 21. Microphase Separated Cation Conducting Polymers : Design, Synthesis, and Properties

    Author : Hannes Nederstedt; Centrum för analys och syntes; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Polymer; Litiumbatteri; Mikrofasseparering; Bränslceller; Elektrolyt; Polymerelektrolyt; Polymera bränslecellsmembran; Polymer electrolyte fuel cells; Polymer electrolyte; Polymer electrolyte membrane; Microphase separation; Lithium battery; Polymer; Fuel cell; Proton exchange membrane PEM ;

    Abstract : 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. READ MORE

  4. 22. Conducting Redox Polymers for Electrode Materials : Synthetic Strategies and Electrochemical Properties

    Author : Xiao Huang; Adolf Gogoll; Martin Sjödin; Maria Strømme; David Mecerreyes; Berit Olofsson; Fredrik Björefors; Tom Lindfors; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Organic electrode material; Energy storage; Conducting redox polymer; Polythiophene; Terephthalate; PEDOT; Chemistry with specialization in Organic Chemistry; Kemi med inriktning mot organisk kemi;

    Abstract : Organic electrode materials represent an intriguing alternative to their inorganic counterparts due to their sustainable and environmental-friendly properties. Their plastic character allows for the realization of light-weight, versatile and disposable devices for energy storage. READ MORE

  5. 23. Imidazole containing polymers complexed with Cu2+ and Zn2+

    Author : Markus Andersson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; vibrational spectroscopy; far-FTIR; EPR; cross-linking; DSC; Coordinating polymer; imidazole; mid-FTIR; metal ion;

    Abstract : An enormous problem for the shipping industry is fouling of marine organisms such as algae andbarnacles on the boat hull. The negative consequences for the society are both economical as well asenvironmental. To prevent fouling in general, biocides are typically incorporated directly into the paint. READ MORE

  6. 24. Structure control by phase separation and influence on mass transport in films for controlled release

    Author : Helene Andersson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Controlled release; Coating; Cellulose derivatives; Hydroxypropyl cellulose; Solvent evaporation; Ethyl cellulose; Phase separation; Polymer blend; Molecular weight;

    Abstract : Controlled release coatings for oral pharmaceutics are often made of cellulose derivatives. Such coatings can be used to promote a prolonged therapeutic concentration in the blood by a slow drug delivery in the gastrointestinal tract. READ MORE
