  4. 3. Melt flow and surface stability effects on polymer flammability : A study on polystyrene, flexible polyurethane foam and polyolefin composites

    Författare :Roland H. Krämer; Ulf W. Gedde; Norman C. Billingham; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Melt; flow; dripping; collapse; combustion; pool fire; feed‐back; gasification; heat release; flammability; nanocomposites; molar mass; intumescence; polyurethane; Polymer chemistry; Polymerkemi;

    Sammanfattning : Our ability to accurately determine the flammability properties of polymers is hampered bythe erratic effects of deformation and liquid flow that occur during polymer combustion.This study aims to improve the understanding of such effects at several levels: The often obvious impact of melt flow on standardized flammability test methods forelectrical appliances is described to identify the need and to motivate others to worktowards an improved material characterization.

  5. 4. Phase separation, aggregation and gelation of a charged helixforming polysaccharide in aqueous salt solution

    Författare :Johan Borgström; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; polysaccharide; physical gel; ion binding; carrageenan; liquid crystal; polymer; Fysikalisk kemi;

    Sammanfattning : The phase behaviour and gelation of the anionic polysaccharide kappa-carrageenan (KC) in different salt solutions was studied. The specific site binding of certain anions and certain cations to the KC helix was used as a means of controlling the interactions. LÄS MER

  7. 5. CO2 Capture through Integration of Aqueous and Immobilized Deep Eutectic Solvents

    Författare :Sahar Foorginezhad; Xiaoyan Ji; Hailong Li; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CO2 capture; Ionic liquid; Deep eutectic solvent; Immobilization; Slurry.; Energiteknik; Energy Engineering;

    Sammanfattning : The growing global concern over rising CO2 emissions and its significant impact on climate change highlight the urgent need for efficient CO2 capture technologies. Among the array of techniques employed for this purpose, chemical absorption stands out, characterized by high capture capacity, promising efficiency, and versatile applicability. LÄS MER
