  1. 1. The Use of Lignin Derivatives to Improve Selected Paper Properties

    Author : Stefan Antonsson; Mikael E. Lindström; Gunnar Henriksson; Mats Johansson; Docent Roland Agnemo Tek. Dr. Harald Brelid; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; kraft lignin; black liquor; cross-flow filtration; lignin derivative; kraftliner; oxidative coupling; laccase; manganese; linseed oil; mechano-sorptive creep; kraftlignin; svartlut; tvärsflödesfiltrering; ligninderivat; kraftliner; oxidativ koppling; lackas; mangan; linolja; mekanosorptivt kryp; Cellulose and paper engineering; Cellulosa- och pappersteknik;

    Abstract : Ved består huvudsakligen av tre typer av polymerer, cellulosa, hemicellulosa och lignin. Lignin bildas i naturen genom enzymatiskt initierad oxidativ koppling av tre olika typer av fenylpropan-enheter. Dessa bygger genom olika kol-kol- och kol-syre-bindningar upp en amorf tredimensionell polymer. READ MORE

  3. 3. Exploring fatty acid derivatives from renewable resources as raw materials for coating applications

    Author : Samer Nameer; Mats Johansson; Mats Martinelle; Dean Webster; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; epoxy; vegetable oils; birch bark; thermoset; bio-based; fatty acid; renewable resources; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : In the work presented herein, epoxy fatty acid derivatives were explored in the formation of thermosets for coating applications. The epoxy fatty acid derivatives were obtained from renewable resources such as birch tree bark and epoxidized linseed oil. READ MORE

  4. 4. Chemical Interactions between Fatty Acids and Wood Components during Oxidation Processes

    Author : Alireza Salehi M.; Mats K G Johansson; Gunnar Hemriksson; Heikki Tenhu; KTH; []
    Keywords : ;

    Abstract : Fatty acids auto-oxidation on wood is proposed to follow a complex free radical interaction mechanism. The aim of this study was to analyze the effect of wood constituents on oxidation of fatty acids and thereby the entire drying process, and to characterize the fatty acids-wood interaction by using analytical instruments such as RT-IR and NMR.

  5. 5. Effect of Wood Constituents Oxidation of Unsaturated Fatty Acids

    Author : Alireza Salehi Movahed; Mats K.G. Johansson; Mats Johnssson; Karin Jacobsson; KTH; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Wood constituents; oil; oxidation; unstatured fatty acids; lignin; model lignin compounds; Polymer chemistry; Polymerkemi;

    Abstract : This work presents the mechanisms of free radicals in a model system between fatty acids oxidation process and wood components. The aim is to create a better understanding of new environmentally friendly materials for exterior wood protection. READ MORE
