2. 1. On processing of thermoplastic starch

   Author : Mats Thunwall; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; amylose; starch; extrusion; thermoplastic starch;

   Abstract : Starch is a biodegradable material produced in many different crop plants. Since it is biodegradable, inexpensive, generally has good barrier properties and comes from a renewable source it would be an ideal material to use in e.g. packaging applications. READ MORE

4. 2. 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

5. 3. Processing and Properties of Expanded Starch Materials

   Author : Mia Sjöqvist; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; amylopectin; extrusion; starch; porosity; foams; moisture content; amylose; microwave treatment; absorption;

   Abstract : The need to strive towards a more sustainable development of the society is becoming increasingly urgent. As the population of the world is growing so is society´s impact on the environment. This is causing environmental problems with growing amounts of waste. READ MORE

6. 4. Plasticization of Biobased Polymers: A Combined Experimental and Simulation Approach

   Author : Hüsamettin Deniz Özeren; Mikael S. Hedenqvist; Richard Olsson; Fritjof Nilsson; Kim Bolton; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; plasticization; starch; gluten; simulation; molecular dynamics; glycerol; mjukgörning; stärkelse; gluten; simulering; molekyldynamik; glycerol; Fiber- och polymervetenskap; Fibre and Polymer Science;

   Abstract : The field of bio-based plastics has developed significantly in recent decades and there is an increasing demand for industries to shift from petrochemical to biobased polymers. Biobased polymers offer competitive properties, and in many cases have advantages in terms of cost. READ MORE

7. 5. Mechanical properties of flax fibers and their composites

   Author : Edgars Sparnins; Kristofer Gamstedt; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Flax fibers; natural fiber composites; mechanical properties; Time dependent behavior; Polymera konstruktionsmaterial; Polymeric Composite Materials;

   Abstract : Flax fibers, along with a number of other natural fibers, are being considered as an environmentally friendlier alternative of synthetic fibers in fiber-reinforced polymer composites. A common feature of natural fibers is a much higher variability of mechanical properties. READ MORE
