  2. 1. Crystallinity and Morphology of Starch Polymers in Films

    Author : Åsa Rindlav Westling; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; morphology; amylose; surface; thermal transitions; amylopectin; starch; crystallinity; film;

    Abstract : Starch is a renewable material that can be converted into biodegradable plastic products, or films with excellent oxygen barrier properties. Films of potato starch, amylose, amylopectin and blends thereof were made by solution casting. READ MORE

  4. 2. Material Properties of Starch and Cereal Protein Films and Foams

    Author : Thomas Gillgren; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; foam; avenin; oxygen permeability; amylopectin; water vapour permeability; plasticization; mechanical properties; zein; film; glass transition temperature; kafirin; prolamin; cereal protein; amylose; starch;

    Abstract : Materials that are renewable and biodegradable are demanded for environmental reasons. Biopolymeric materials, such as materials from starch and cereal proteins, are both renewable and biodegradable. However, starch and cereal protein materials are generally rather brittle and therefore need to be plasticized to become more flexible. READ MORE

  5. 3. Thermoplastic processing of starch and cellulose-containing polymers

    Author : Mats Thunwall; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermoplastic starch; amylose; extrusion; injection moulding; polymers; cellulose; film blowing; composite;

    Abstract : Starch and cellulose are two naturally occurring polymers that have the potential to reduce the dependence on fossil resources if used as replacements or as complements to synthetic polymers. There are however some problems associated with the use of these polymers that have to be addressed and solved. READ MORE

  6. 4. Bio-inspired cellulose nanocomposites and foams based on starch matrix

    Author : Anna Svagan; Lars A. Berglund; Salvatore Iannace; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; starch; cellulose nanofibers; foam; nanocomposites; cushioning materials; biodegradable; expanded polystyrene; mechanical properties; diffusion; Polymer chemistry; Polymerkemi;

    Abstract : In 2007 the production of expanded polystyrene (EPS) in the world was over 4 million tonnes and is expected to grow at 6 percent per year. With the increased concern about environmental protection, alternative biodegradable materials from renewable resources are of interest. READ MORE

  7. 5. From Starch to Starch Microspheres. Formation of an Ordered Structure during Processing

    Author : Lidia Elfstrand; Livsmedelsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknik; Pharmaceutical and related technologies; Läkemedelsteknik och relaterad teknik; crystallization; Technological sciences; starch microspheres; protein delivery;

    Abstract : Starch microsphere is a dosage form suitable for the encapsulation of protein drugs. The starch microspheres investigated in this thesis are intended for release of the drug in a pre-designed way, or in controlled manner. READ MORE
