  1. 11. A toolbox for improving the processability of composites with a high content of thermomechanical pulp

    Författare :Seyedehsan Hosseini; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; interface.; thermomechanical pulp; magnesium stearate; mechanical properties; composite; molybdenum disulfide; AKD;

    Sammanfattning : The use of oil-based products causes large volumes of non-biodegradable waste and contributes to climate changes. Focus has consequently shifted towards the use of polymers derived from wood. The processability of such polymers, however, presents a challenge but this can be overcome through the use of composite materials, i.e. LÄS MER

  3. 12. Advanced polymeric scaffolds for functional materials in biomedical applications

    Sammanfattning : Sustainable wood nanotechnologies that combine optical transmittance and mechanical performance are interesting for new functionalities utilizing transparency. Wood is a sophisticated bio-based material with a natural hierarchical, anisotropic and porous structure. LÄS MER

  7. 15. 3D-Printing of Fluorinated Polymer-based Materials for Plasmonic Sensing

    Författare :Ida Östergren; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; 3D-printing; polymer nanocomposite; hydrogen sensing; plasmonic nanoparticles; Teflon AF; fused deposition modeling;

    Sammanfattning : Hydrogen attracts growing interest as a versatile energy carrier, serving as a fuel for cars, a heat source, or a reagent for chemical synthesis. At the same time, the demand for accurate and selective hydrogen sensors is increasing because of both safety concerns and the need for process monitoring. LÄS MER
