  1. 1. Protein-based Packaging Films, Sheets and Composites: Process Development and Functional Properties

    Författare :Sung-Woo Cho; Mikael Hedenqvist; Amar K. Mohanty; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; wheat gluten; solution casting; compression molding; extrusion; injection molding; aging; migration; opacity; heat sealability; hemp fiber; laminate; polylactic acid; clay; nanocomposites.; Other chemical engineering; Övrig kemiteknik;

    Sammanfattning : The depletion of the petroleum resources and a number of environmental concerns led to considerable research efforts in the field of biodegradable materials over the last few decades. Of the diverse range of biopolymers, wheat gluten (WG) stands out as an alternative to synthetic plastics in packaging applications due to its attractive combination of flexibility and strength, high gas barrier properties under low humidity conditions and renewability.

  3. 2. Modeling the mechanical performance of natural fiber composites

    Författare :Erik Marklund; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymera konstruktionsmaterial; Polymeric Composite Materials;

    Sammanfattning : Due to environmental concerns the interest in use of renewable and recyclable materials has dramatically increased over the recent years. Wood and other lignocellulosic fiber reinforced polymers have large potential as structural materials due to the high specific stiffness, high specific strength and high aspect ratio of the fibers.

  4. 3. Mechanics of microdamage development and stiffness degradation in fiber composites

    Författare :Johannes Eitzenberger; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymeric Composite Materials; Polymera konstruktionsmaterial;

    Sammanfattning : Damage in composites reduces its performance and durability and thus its usefulness. The common subject in all papers presented in the licentiate thesis is distributed microdamage, and the materials of interest are a Hemp/Lignin natural composite and glass/carbon fiber reinforced plastics composites.

  5. 4. 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

  7. 5. Development of hierarchical cellulosic reinforcement for polymer composites

    Författare :Abdelghani Hajlane; Angelika Bachinger; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymera konstruktionsmaterial; Polymeric Composite Materials;

    Sammanfattning : Cellulose is an environmentally friendly material which is obtainable in vast quantities, since it is present in every plant. Cellulosic fibers are commercially found in two forms: natural (flax, hemp, cotton, sisal, wood, etc.) and regenerated cellulose fibers (RCF). LÄS MER
