  4. 13. Assembly and alignment in cellulose nanomaterial-based composite dispersions and thermally insulating foams

    Författare :Pierre Munier; Lennart Bergström; Aji Mathew; Steve Eichhorn; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cellulose nanomaterials; composites; assembly; alignment; x-ray scattering; foams; thermal insulation; mechanical strengthening; Materials Chemistry; materialkemi;

    Sammanfattning : Research on nanoparticles extracted from renewable and highly available sources is motivated by both the development of functional nanomaterials and the drive to replace widely used materials based on fossil resources. In particular, cellulose, in the form of cellulose nanomaterials (CNM), has attracted increased attention for the development of sustainable and high performance products, thanks to properties that include high specific mechanical strength, chemical versatility and anisotropic thermal conductivity.
