  1. 11. Influence of paper properties and polymer coatings on barrier properties of greaseproof paper

    Författare :Henrik Kjellgren; Gunnar Engström; Lars Järnström; Lennart Stolpe; Torbjörn Helle; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Greaseproof paper; Barrier properties; Gas barrier; Paper properties; Coatings; Chemical engineering; Kemiteknik; Chemical Engineering; Kemiteknik;

    Sammanfattning : Greaseproof paper has a dense structure and therefore provides a natural barrier against materials like fat and oils. The barrier is obtained by extensive refining of the pulp. LÄS MER

  3. 12. 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.

  4. 13. Interactions between Polymers in Dispersion Coating and Surface Sizing of Paper and Board

    Författare :Caisa Johansson; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical Engineering; Kemiteknik;

    Sammanfattning : Barrier dispersion coatings are applied to paper or board in order to lower the permeability of the material to liquids and gases. In the present study, the film formation and barrier properties of latices used for coating applications were investigated. LÄS MER

  5. 14. Preparation of Electroconductive Paper by Deposition of Conducting Polymer

    Författare :Elson Montibon; Magnus Lestelius; Lars Järnström; Agne Swerin; Karlstads universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER
