  1. 1. Cellulose-water interaction: a spectroscopic study

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Erik L Lindh; KTH.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; cellulose; water; hydrogen exchange; deuterium; NMR spectroscopy; FT-IR spectroscopy; Kemi; Chemistry;

    Abstract : The human society of today has a significantly negative impact on the environment and needs to change its way of living towards a more sustainable path if to continue to live on a healthy planet. One path is believed to be an increased usage of naturally degradable and renewable raw materials and, therefore, attention has been focused on the highly abundant biopolymer cellulose. READ MORE

  2. 2. On the Solubility of Wood Hemicelluloses in Water and its Influence on the Adsorption at Cellulose/Water Interfaces

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Saina Kishani; KTH.; [2019]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wood; Hemicellulose; Solubility; Adsorption; Interaction; Cellulose; Size distribution;

    Abstract : Hemicelluloses are a group of natural polysaccharides and one of the main components of wood. The availability and biodegradability of these polymers have created a great interest in developing new bio-based materials or composites from these materials for different end-use purposes.

  3. 3. Cellulose nanofibril materials with controlled structure the influence of colloidal interactions

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Andreas Fall; KTH.; [2011]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Colloidal stability; cellulose nanofibrils; nanofibers; nanostructured materials; biocomposite; DLVO; gel;

    Abstract : Nanoparticles are very interesting components. Due to their very large specific surface area they possess properties in between molecules and macroscopic materials. In addition, a material built up of hierarchically assembled nanoparticles could obtain unique properties, not possessed by the nanoparticles themself. READ MORE

  4. 4. Ethyl(hydroxyethyl)cellulose and Some Model Uncharged Polymers: A Calorimetric Study of Their Interaction with Surfactants in Aqueous Solution

    University dissertation from Department of Biochemistry, Lund University

    Author : Geng Wang; Lund University.; Lunds universitet.; [1997]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; calorimetry; differntial scanning; isothermal titration; enthalpy; electrolyte; micelles; self-association; thermal gelling; interaction; alkyltrimethylammonium halides; sodium dodecylsulfate; surfactants; polymers; ethyl hydroxylethyl cellulose; viscosity; phase behavior; self-diffusion NMR; Physics; Fysik; Chemistry; Kemi;

    Abstract : The interactions between uncharged polymers, e.g. ethyl(hydroxylethyl)cellulose (EHEC) and some model polymers, and ionic surfactants in aqueous solution has been studied by using isothermal titration and differential scanning calorimetry. READ MORE

  5. 5. Cellulose Nanofibril Networks and Composites Preparation, Structure and Properties

    University dissertation from Stockholm : KTH

    Author : Marielle Henriksson; KTH.; [2008]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cellulose nanocomposites; microfibrillated cellulose; nanofibrils; biofibers; mechanical properties; deformation mechanisms; molar mass; endoglucanase; TECHNOLOGY Materials science; TEKNIKVETENSKAP Teknisk materialvetenskap;

    Abstract : Träbaserade cellulosananofibriller är intressanta som förstärkande fas i polymera nanokompositer; detta främst på grund av den kristallina cellulosans höga styvhet och på grund av nanofibrillernas förmåga att bilda nätverk. Cellulosananofibriller kan användas i form av mikrokristallin cellulosa, MCC, som har lågt längd/diameter förhållande, eller i form av mikrofibrillerad cellulosa, MFC, med högt längd/diameter förhållande.
