  1. 1. Biocomposites Based on Core-Shell Cellulose Nanofibers : Preparation, Structure, and Properties

    Författare :Kasinee Prakobna; Lars Berglund; David Plackett; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biocomposites; cellulose nanofibers; polysaccharides; holocellulose; nanostructure; dispersion; mechanical properties; hygromechanical properties; moisture stability; film; porous material; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : Cellulose nanofibers (CNFs) are of interest as load-bearing components for polymer matrix nanocomposites. A wide range of nanostructured materials including nanopaper/films, foams, aerogels, and hydrogels can be prepared from CNFs. The material performance can be fine-tuned when CNFs are combined with different polymer matrices. LÄS MER

  3. 2. Carbon Nanotube Polymer Composites: Mechanical, Electrical and Photorefractive Properties

    Författare :Liliana Licea Jimenez; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; carbon nanotubes; electrical properties; photorefractive properties.; polymer matrix nanocomposites; mechanical properties;

    Sammanfattning : Incorporation of carbon nanotubes (CNT) into polymers is attractive due to the generally good processability of polymers and unprecedented properties of nanotubes. In this work, preparation and matrix known earlier but not employed so-far for nanocomposites are studied towards enhanced mechanical and electrical performances. LÄS MER

  5. 4. Mechanical Properties of Gamma Titanium Aluminides

    Författare :Viktor Recina; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; microstructure; intermetallic compound; tensile properties; diffusion bonding; sample preparation; low cycle fatigue; fractography; gamma titanium aluminide; mechanical properties;

    Sammanfattning : In recent years intermetallic compounds have attracted a great deal of attention as structural materials. Among the intermetallics, gamma titanium aluminides (.gamma.-TiAl) are considered to be closest to application. LÄS MER

  7. 5. Influence of paper properties and polymer coatings on barrier properties of greaseproof paper

    Författare :Henrik Kjellgren; Gunnar Engström; Lars Järnström; Lennart Stolpe; Torbjörn Helle; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Greaseproof paper; Barrier properties; Gas barrier; Paper properties; Coatings; Chemical engineering; Kemiteknik; Chemical Engineering; Kemiteknik;

    Sammanfattning : Greaseproof paper has a dense structure and therefore provides a natural barrier against materials like fat and oils. The barrier is obtained by extensive refining of the pulp. LÄS MER
