  2. 2. Modification of Paper into Conductive Substrate for Electronic Functions Deposition, Characterization and Demonstration

    University dissertation from Karlstad : Karlstad University

    Author : Elson Montibon; Karlstads universitet.; [2011]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ionic paper; electroconductive paper; flexible electronics; conducting polymer; ionic liquids; fiber network; TECHNOLOGY Chemical engineering Chemical process and manufacturing engineering Cellulose and paper engineering; TEKNIKVETENSKAP Kemiteknik Kemisk process- och produktionsteknik 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.

  3. 3. Formation and properties of polyelectrolyte multilayers on wood fibres  influence on paper strength and fibre wettability

    University dissertation from Stockholm : KTH

    Author : Rikard Lingström; KTH.; [2006]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; polyelectrolyte; multilayer; adsorption; reflectance; contact angle; dynamics; paper; mechanical properties; individual; wood fibre; NATURAL SCIENCES Chemistry; NATURVETENSKAP Kemi;

    Abstract : The work in this licentiate thesis examines the adsorption of polyelectrolyte multilayers (PEM) onto wood fibres as a new way to influence the properties of the fibre surfaces and hence the fibres. Fundamental aspects of PEM formation on wood fibres have been studied, and discussed in terms of paper strength and wood fibre wettability. READ MORE

  5. 5. Formation of Block Copolymer and Surfactant Vesicles

    University dissertation from Karin Bryskhe, Villav. 8, 232 53 Åkarp

    Author : Karin Bryskhe; Lund University.; Lunds universitet.; [2004]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Polymerteknik; Fysikalisk kemi; biopolymers; Polymer technology; nanoparticles; Lipid; triblock copolymer; surfactants; Nonionic; Vesicles; Formation; Physical chemistry;

    Abstract : In this thesis temperature induced vesicle formation in both a block copolymer system and nonionic surfactant system have been investigated. The block copolymer is a triblock copolymer of poly(ethylene oxide) (PEO) and poly(propylene oxide) (PPO), PEO-PPO-PEO, with the average molecular composition of EO5PO68EO5 and the commercial trade name Pluronic L121 (papers I, II).
