  2. 1. Bio-inspired polysaccharide nanocomposites and foams

    Author : Anna Svagan; Lars Berglund; Mats Stading; KTH; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cellulose; starch; microfibrillated cellulose; biomimetic; nanocomposite; nanocomposite foam; mechanical properties; Biomaterials; Biomaterial;

    Abstract : Today, the majority of materials used for single-use packaging are petroleum-based synthetic polymers. With increased concern about the environmental protection, efforts have been made to develop alternative biodegradable materials from renewable resources. Starch offers an attractive alternative since it is of low cost and abundant. READ MORE

  4. 2. Biodegradable Blends and Nanocomposite Films with Amylopectin, Poly(lactic acid) and Chitosan Matrices

    Author : David Nordqvist; Mikael S. Hedenqvist; Mats Stading; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; amylopectin; chitosan; microfibrillated cellulose; nanocomposite; montmorillonite; coupling agent; amylopektin; kitosan; mikrofibrillär cellulose; nanokomposit; montmorillonit; kompatibilisator; Polymer chemistry; Polymerkemi;

    Abstract : Användningan av engångsförpackningar har ökat kraftigt de senaste åren. Den absolut största delen av dessa förpackningar tillverkars av oljebaserade plaster såsom polyetylen (PE) och polypropylen (PP). Dessa har även en oerhört lång nedbrytningstid, vilket gör det viktigt att finna mer miljövänliga alternativ. READ MORE

  5. 3. Towards compatibilization of cellulose nanofibrils in polymer matrices : Polymer design for mediating the nanofibril–matrix interface

    Author : Rosella Telaretti Leggieri; Eva Malmström; Mats Johansson; Catarina de Carvalho Esteves; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Cellulose nanofibril CNF ; copolymer; nanocomposite; coating; reinforcement; interface; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : Magnifying the nanostructure of wood reveals the features of an extraordinary nanocomposite material. In this nanocomposite, long fibrils of semicrystalline cellulose, with a cross-section in the nanometer range and length up to several micrometers, are embedded in an amorphous matrix made of other polymeric components.

  6. 4. Long-term Properties of Sustainable Polymeric Materials : Mechanical Recycling and Use of Renewable Resources

    Author : Emma Strömberg; Sigbritt Karlsson; Amparo Ribes-Greus; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Sustainable materials; mechanical recycling; polyolefin; reprocessing; accelerated ageing; chromatography; biofilm; microenvironment chamber; environmental degradation; biocomposite; nanocomposite; Polymer chemistry; Polymerkemi;

    Abstract : New strategies for management of the accumulating amounts of plastic waste are required, to achieve a sustainable development in terms of material production and use. After service life, the materials should be recovered and recycled efficiently to provide a valuable resource for future applications. READ MORE

  7. 5. Compression-moulded and multifunctional cellulose network materials

    Author : Sylvain Galland; Lars Berglund; Naceur Belgacem; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; compression-moulding; cellulose fibre; nanocomposite; magnetic nanoparticle; epoxy; UV curing; oxygen barrier;

    Abstract : Cellulose-based materials are widely used in a number of important applications (e.g. paper, wood, textiles). Additional developments are suggested by the growing interest for natural fibre-based composite and nanocomposite materials. READ MORE
