  3. 17. Characteristics of wood plastic composites based on modified wood : Moisture properties, biological performance and micromorphology

    Författare :Kristoffer Segerholm; Magnus Wålinder; Mark Hughes; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wood plastic composites; WPC; acetylation; thermal modification; furfurylation; moisture sorption; biological durability; UV excimer laser; micromorphology;

    Sammanfattning : Biobased materials made from renewable resources, such as wood, play an important role in the sustainable development of society. One main challenge of biobased building materials is their inherent moisture sensitivity, a major cause for fungal decay, mold growth and dimensional instability, resulting in decreased service life as well as costly maintenance.
