1. 1. Polymer extraction and utilization of brown algal biomass

   Författare :Martin Sterner; Ulrica Edlund; Fredrik Gröndahl; Marguerite Rinaudo; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Algae; Saccharina latissima; alginate; brown seaweed; extraction; filament; chelation; gel; Fiber- och polymervetenskap; Fibre and Polymer Science;

   Sammanfattning : Aquaculture is a field with a world changing potential. The areas at sea are enormous and aquatic cultivations impact both the environment and local ecology far less than land based cultivations. In the realm of algae, abundancies exists of nutrition, water and accessible sunlight, but there is constant shortage of places to dwell. LÄS MER

3. 2. Controlled Polymer Grafting from Nanoparticles for the Design of Dielectric Nanocomposites

   Författare :Martin Wåhlander; Eva Malmström; Anna Carlmark; Henrik Hillborg; Sanat K. Kumar; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fiber- och polymervetenskap; Fibre and Polymer Science;

   Sammanfattning : The interest for polymeric nanocomposites has rapidly grown during the last decades, fuelled by the great potential and superior properties of nanoparticles (NPs). The production volumes of commercial NPs have increased exponentially during the last ten years, and the quality has been significantly improved. LÄS MER

4. 3. Influence of liquid diffusion on the performance of polymer materials in industrial applications

   Författare :Stefanie Römhild; Mikael Hedenqvist; Lars Berglund; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LCP; Vectra A950; thermoset resin; FRP; diffusion; disclination; annealing; lining; bonding; long-term properties in water; Polymer chemistry; Polymerkemi;

   Sammanfattning : Diffusion of liquids into and through polymers is an important factor that negatively may influence the durability or lifetime of a polymer structure used in industrial applications. In this work two types of polymers, a liquid crystalline polymer (LCP, Vectra A950) and various thermoset resins as used in fibre reinforced plastics (FRP) process equipment were studied with regard to barrier properties, chemical resistance and long-term performance.

5. 4. Induction heating of carbon fibre reinforced polymer composites : Characterization and modelling

   Författare :Fredrik Lundström; Industriell Produktion; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Carbon fibre reinforced polymers; Induction heating; Material characterization; Thermal properties; Electrical conductivity; Numerical modelling;

   Sammanfattning : Carbon fibre reinforced polymers (CFRP) are lightweight materials with great potential due to their high strength and stiffness relative to their weight. This enables weight reduction in, for example, vehicles, which is important in reducing energy consumption. LÄS MER

7. 5. Renewable Composites Prepared from Biobased Thermoset Resins

   Författare :Dan Åkesson; Högskolan i Borås; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Renewable; natural fibre; composite; biobased thermoset resin;

   Sammanfattning : In our efforts to create a more sustainable society, several researchers have tried to prepare composites from renewable materials in recent years. The use of natural fibres for reinforcement of composites has been relatively well studied. LÄS MER
