  2. 16. Tailoring Adhesion and Wetting Properties of Cellulose Fibres and Model Surfaces Using Layer-by-Layer Technology

    Author : Emil Gustafsson; Lars Wågberg; Gero Decher; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : The versatile layer-by-layer (LbL) technique, for consecutive adsorption of polyelectrolytes and charged nanoparticles onto a substrate, was used to modify cellulose fibres and model surfaces for improved mechanical and wetting properties. In addition to being used to modify cellulose substrates, the LbL technique was also used to create cellulose surfaces suitable for high resolution adhesion measurements. READ MORE

  7. 20. Biodegradable nanocomposite films based on amylopectin and chitosan

    Author : David Nordqvist; Mikael Hedenqvist; Lars Berglund; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Polymer chemistry; Polymerkemi;

    Abstract : The use of disposable material is rapidly increasing, today the absolute majority of the material used for these application, i.e. food packages, are oil-based plastics such as polyethylene and polypropylene. Therefore it is of great importance to find alternative biodegradable materials made from renewable resources for this huge growing market. READ MORE
