1. 11. Evolution and control of the three dimensional functional microstructure of Polymer:Fullerene photovoltaic blends

   Författare :Olof Bäcke; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; crosslinking; fullerene crystals; tomography; transmission electron mi- croscopy; organic solar cell; in situ; polymer:fullerene film; thermal degradation;

   Sammanfattning : Polymer:fullerene bulk-heterojunction thin films show great promise for use as active layers in organic solar cells. However, their low thermal stability is a hindrance that complicates the manufacturing and influences the lifetime of devices. LÄS MER

3. 12. Quantitative 3D reconstruction of porous polymers using FIB-SEM tomography -correlating materials structures to properties of coatings for controlled drug release

   Författare :Cecilia Fager; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; tomography; controlled drug release; 3D; connectivity; insulating material; polymer film; soft material; focused ion beam; scanning electron microscopy;

   Sammanfattning : Porous networks are found in a wide range of different advanced and technologically important materials and influence the materials properties. The networks are active components in for example batteries, food and pharmaceuticals. The interconnectivity of a network strongly influences the transport properties. LÄS MER

4. 13. Thermally cured coil-coatings utilizing novel resins and fatty acid methyl esters as reactive diluents

   Författare :Katarina Johansson; Mats Johansson; Rolf van Benthem; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Coatings; Coil-coatings; Thermal cure; Reactive diluents; Fatty acids; Transesterification; Hyperbranched polyester resins; Film properties; Polymer chemistry; Polymerkemi;

   Sammanfattning : Solvent-borne thermally cured coil-coating resins contain large amounts of volatile organic solvents in order to obtain suitable flow for film application. This work describes how the expensive and environmental hazardous volatile organic solvent content of a solvent-borne thermally cured polyester/melamine coil-coating system can be reduced by introduction of fatty acid methyl esters (FAMEs) as reactive diluents and modification of the polyester binder resin.

5. 14. Fatty acid methyl esters as reactive diluents in solvent-borne thermally cured coil-coatings

   Författare :Katarina Johansson; Mats Johansson; Mats Jonsson; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fatty acids; Reactive diluents; Coatings; Thermal curing; Transesterification; Film properties; Polymer chemistry; Polymerkemi;

   Sammanfattning : This work describes how a fatty acid methyl ester (FAME) derived from a vegetable oil can be introduced as reactive diluent in a solvent-borne thermally cured coil-coating system. The evaluated reactive diluent, rape seed methyl ester (RME), has been evaluated both in a fully formulated clear coat system and via model studies. LÄS MER

7. 15. Electrolyte-Gated Organic Thin-Film Transistors

   Författare :Lars Herlogsson; Magnus Berggren; Hagen Klauk; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Organic electronics; Thin-film transistor; Organic semiconductor; Polymer; Electrolyte; Polyelectrolyte; Electronics; Elektronik;

   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
