    Abstract : In this thesis, bio-nanocomposites made from two alternative biopolymers and montmorillonite (Mnt) clay have been investigated by molecular modelling. These biopolymers are xyloglucan (XG) and chitosan (CHS), both of which are abundant, renewable, and cost-effective. READ MORE

  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; Luleå tekniska universitet.; [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.
