  2. 11. 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.

  4. 12. Coagulation of Cellulose: from Ionic-Liquid Solution to Cellulose Nanostructure

    Author : Artur Hedlund; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Wet Spinning; Cellulose; Ionic Liquids; Diffusion; Coagulation; Nonsolvent;

    Abstract : Abstract A linear chain of glucose monomers, cellulose, provides the structural reinforcement of the cell walls of plants and constitutes almost half of their dry mass. Wood and other plant-based raw materials are processed on a large industrial scale to isolate the cellulose, which is then dissolved. READ MORE

  5. 13. Design of Cellulose-Based Electrically Conductive Composites: Fundamentals, Modifications, and Scale-up

    Author : Karishma Jain; Lars Wågberg; Per A. Larsson; Davide Beneventi; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Cellulose nanofibrils; PEDOT:PSS; chemically-modified cellulose fibers; fundamental interactions; bioelectronics; energy storage; conductive paper production; large-scale production; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : Modern demand for consumer electronics is fueling the generation of 'E-waste.' Furthermore, theraw materials and manufacturing methods used in the fabrication of electronics are not sustainable. READ MORE

  6. 14. Pyrolysis of mixed plastics and paper to produce fuels and other chemicals

    Author : Nanta Sophonrat; Weihong Yang; Linda Sandström; Tobias Richards; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Pyrolysis; Mixed plastics and biomass; Cellulose; Refuse derived fuels RDF ; Paper rejects; Interactions; Stepwise pyrolysis; Calcium oxide CaO ; Chemical Engineering; Kemiteknik; Energy Technology; Energiteknik;

    Abstract : As the world population and economy grow, higher consumption results in higher waste packaging, plastics and paper residues. Pyrolysis offers a way to recover fuels and other chemicals from this waste fraction. READ MORE

  7. 15. Carbon fibres from lignin-cellulose precursors

    Author : Andreas Bengtsson; Monica Ek; Jim Parkås; Daniel Söderberg; KTH; []
