  1. 1. Aging and heat-sealing properties of films based on wheat gluten

    Författare :Sung-Woo Cho; Mikael Hedenqvist; Minna Hakkarainen; Mikael Lindström; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wheat gluten; aging; migration; opacity; heat sealability; shear strength; Polymer chemistry; Polymerkemi;

    Sammanfattning : Recently the research interest of the possibility of using wheat gluten (WG) as packaging material has greatly increased due to its combination of high gas barrier, attractive mechanical, film-forming and renewable properties. The source is also readily available and inexpensive on a worldwide basis. LÄS MER

  3. 2. 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.

  4. 3. Hygrothermal Durability of Adhesively Bonded FRP/steel Joints

    Författare :Mohsen Heshmati; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cohesive zone modelling; durability; moisture diffusion; Fibre reinforced polymer; adhesively bonded FRP steel joints; long-term performance;

    Sammanfattning : Fibre reinforced polymer (FRP) composites offer superior mechanical properties, such as specific strength and stiffness, corrosion resistance and light weight. Over the past four dec-ades, FRPs have been increasingly used for strengthening and repair of bridge structures, and more recently, in the manufacture of whole/hybrid FRP bridges. LÄS MER

  5. 4. Processing and Development of Wheat Gluten Plastics

    Författare :Henrik Ullsten; Mikael S. Hedenqvist; Nathalie Gontard; KTH; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Wheat Gluten; Extrusion; Processing; Chemistry; Kemi;

    Sammanfattning :  Renewable packaging materials are of interest for a more sustainable environment. Wheat gluten is one of the most interesting candidates to replace petroleum-based oxygen-barrier polymers for packaging applications. LÄS MER
