  6. 19. Assembly and alignment in cellulose nanomaterial-based composite dispersions and thermally insulating foams

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

    Abstract : 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.

  7. 20. Polyolefin Flame Retardant Cable Materials - Effect of Additives and Copolymer Structure

    Author : Linus Karlsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Calcium Carbonate; Flame Retardant; Silicone Elastomer; Melt Viscosity; Ethylene-Acrylate Copolymer;

    Abstract : Fire safety of cables is becoming increasingly important as the use of electrical equipment steadily increases. Due to their excellent dielectric properties, polyolefin materials are widely used as insulating materials for cables. However, polyolefins are inherently flammable and need to be protected to meet the requirements on flame retardancy. READ MORE
