  3. 3. Acetylation of Solid Wood. Wood Properties and Process Development

    Författare :Pia Larsson Brelid; Chalmers University of Technology; []
    Nyckelord :microwave heating; deformation; wood; hardness; adhesive bonding; power penetration depth; shear strength; delamination; acetylation; pH; bending strength; dielectric properties; stability;

    Sammanfattning : The influence of acetylation on selected wood properties has been determined for Scandinavian pine and spruce wood, in order to predict the behavior of acetylated wood when it is used in different applications. Only minor differences in both bending strength and the modulus of elasticity were obtained for acetylated wood when compared with unmodified wood, and can, for practical applications, be considered unaltered.

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

    Författare :Liliana Licea Jimenez; Chalmers University of Technology; []
    Nyckelord :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
