  1. 6. Mechanical Pulp-Based Nanocellulose : Processing and applications relating to paper and paperboard, composite films, and foams

    Författare :Sinke Henshaw Osong; Per Engstrand; Sven Norgren; Mark Martinez; Mittuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mechanical pulp; thermo-mechanical pulp; chemi-thermomechanical pulp; fractionation; fines; homogenisation; nanocellulose; nano-ligno-cellulose; microfibrillated cellulose; nanofibrillated cellulose; paper; strength properties; crill; TEMPO; nanographite NG ; composite films;

    Sammanfattning : This thesis deals with processing of nanocellulose originating from pulps, with focus on mechanical pulp fibres and fines fractions. The nanocellulose materials produced within this research project were tested for different purposes ranging from strength additives in paper and paperboard products, via composite films to foam materials.

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

    Författare :Elson Montibon; Magnus Lestelius; Lars Järnström; Jouko Peltonen; Karlstads universitet; []
    Nyckelord :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;

    Sammanfattning : 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.
