  1. 1. Dried nanofibrillated cellulose and its bionanocomposites

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Christian Eyholzer; [2011]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Trä och bionanokompositer; Wood and Bionanocomposites;

    Abstract : During the past decade there has been a growing interest in the reinforcement of synthetic polymers with cellulose nanowhiskers and nanofibrillated cellulose (NFC) obtained from plants or bacteria. Their beneficial mechanical properties like high stiffness and strength, in combination with their low mass allowed successful reinforcement of water based polymer dispersions (latexes) for the production of solution cast composite films.

  2. 2. Processing and properties of nanocomposites based on polylactic acid, chitin and cellulose

    University dissertation from Luleå : Luleå University of Technology

    Author : Natalia Herrera Vargas; Kristiina Oksman; Aji P. Mathew; Jyrki Vuorinen; [2017]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nanocomposite; Cellulose; Chitin; Extrusion; Polylactic acid; Trä och bionanokompositer; Wood and Bionanocomposites;

    Abstract : The production of bio-based and biodegradable nanocomposites has gained attention during recent years for environmental reasons; however, the large-scale production of these nanocomposites still poses challenges. The objective of this work has been to prepare bio-based and biodegradable nanocomposites via liquid-assisted extrusion and to gain a deeper understanding of the process and the relationship between the process, composition, structure and properties.

    Abstract : Nanocellulose materials extracted from various types of biomass have recently attracted significant attention. Due to their remarkable mechanical properties, large surface area and biodegradability, they can be promising reinforcements in nanocomposites. READ MORE

  5. 5. Improved properties of thermoplastic wood flour composites

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Kristiina Oksman; [1997]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Trä och bionanokompositer; Wood and Bionanocomposites; Träteknik; Wood Technology;

    Abstract : In this study the properties of composites made of wood flour and thermoplastics have been investigated. In order to improve the interfacial adhesion between hydrophobic and nonpolar thermoplastics and hydrophilic and polar wood flour different additives have been used as compatibilizers in composites systems.
