  2. 1. Paper-based Supercapacitors

    Author : Britta Andres; Håkan Olin; Mats Sandberg; Mittuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; graphene; graphite; paper; nano fibrillated cellulose; supercapacitor; electric double-layer capacitor; energy storage; roll-to-roll; coating; kinetic energy recovery;

    Abstract : The growing market of mobile electronic devices, renewable off-grid energy sources and electric vehicles requires high-performance energy storage devices. Rechargeable batteries are usually the first choice due to their high energy density. However, supercapacitors have a higher power density and longer life-time compared to batteries. READ MORE

  4. 2. Preparation of Electroconductive Paper by Deposition of Conducting Polymer

    Author : Elson Montibon; Magnus Lestelius; Lars Järnström; Agne Swerin; Karlstads universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; electroconductive paper; conducting polymer; adsorption; coating; organic solvents; bulk conductivity; Cellulose and paper engineering; Cellulosa- och pappersteknik; Chemical Engineering; Kemiteknik;

    Abstract : The thesis describes an investigation into the interaction between the conducting polymer and cellulosic materials, and the preparation of electroconductive paper. The adsorption behavior of the conducting polymer onto cellulosic materials was characterized. READ MORE

  5. 3. Heat Transfer and Energy Efficiency in Infrared Paper Dryers

    Author : Magnus Pettersson; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; experimental; modelling; electricity; gas; efficiency; energy; drying; dryer; heat transfer; radiation; paper; infrared; IR; coating; Chemical technology and engineering; Kemiteknik och kemisk teknologi;

    Abstract : Infrared (IR) dryers are widely used in the paper industry, mainly in the production of coated paper grades. The thesis deals with various aspects of heat transfer and energy use in infrared heaters and dryers as employed in the paper industry. Both gas-fired and electric IR dryers are considered and compared. READ MORE

  6. 4. Quantitative microscopy of coating uniformity

    Author : Christina Dahlström; Tetsu Uesaka; Magnus Norgren; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Coating uniformity; coating microstructure uniformity; base sheet effects; argon ion beam milling; scanning electron microscopy; image analysis; binder distributions; autocorrelation analysis; random deposition process; simulation;

    Abstract : Print quality demands for coated papers are steadily growing, and achieving coating uniformity is crucial for high image sharpness, colour fidelity, and print uniformity. Coating uniformity may be divided into two scales: coating thickness uniformity and coating microstructure uniformity, the latter of which includes pigment, pore and binder distributions within the coating layer.

  7. 5. Modification of Paper into Conductive Substrate for Electronic Functions : Deposition, Characterization and Demonstration

    Author : Elson Montibon; Magnus Lestelius; Lars Järnström; Jouko Peltonen; Karlstads universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ionic paper; electroconductive paper; flexible electronics; conducting polymer; ionic liquids; fiber network; Cellulose and paper engineering; Cellulosa- och pappersteknik; Chemical Engineering; Kemiteknik;

    Abstract : The thesis investigates the modification of paper into an ion- and electron-conductive material, and as a renewable material for electronic device. The study stretches from investigating the interaction between the cellulosic materials and the conducting polymer to demonstrating the performance of the conductive paper by printing the electronic structure on the surface of the conductive paper.
