    Nyckelord :vanillin; vitrimer; imine; resin; dynamic covalent bonds; biobased thermoset; photocuring; chemical recyclability; self-healing; digital light processing DLP ; 3D-printing; vanillin; vitrimer; imin; resin; dynamiska kovalenta bindningar; biobaserad härdplast; fotohärdning; kemisk återvinningsbarhet; självläkning; digital light processing DLP ; 3D-utskrift;

    Sammanfattning : Överkonsumtionen av engångsartiklar i fossilbaserad plast är ett av dagens stora miljöproblem. Således finns en efterfrågan på strategier för framställning av biobaserade plaster i allmänhet och härdplaster i synnerhet. LÄS MER

  3. 2. Eco Friendly Composites Prepared from Lactic Acid Based Resin and Natural Fiber

    Master-uppsats, Högskolan i Borås/Institutionen Ingenjörshögskolan

    Författare :Nima Esmaeili; Shahrzad Javanshir; [2014]
    Nyckelord :Biobased thermoset; thermoset poly lactic acid; biobased composite; natural fiber; viscose;

    Sammanfattning : Lactic acid based thermoset were synthesised by reacting lactic acid with glycerol andfunctionalizing lactic acid branches by methacrylic anhydride. Resins with different chainlength were prepared and their thermo mechanical properties were examined through DMAanalysis and their molecular structures were analyzed by NMR method and their viscositywere investigated through rheometry analysis and three monomers were selected as the bestchain length.

  4. 3. Synthesis and characterization of tall oil fatty acid based thermoset resin suitable for natural fiber reinforced composite

    Magister-uppsats, Högskolan i Borås/Institutionen Ingenjörshögskolan

    Författare :Rong Chen; [2012]
    Nyckelord :Tall oil fatty acid; modification; biobased thermoset resin; viscose fibre; biobased composite; compression moulding;

    Sammanfattning : Biobased thermoset resins were synthesized by functionalizing the tall oil fatty acid with hydrogen peroxide and then methacrylic anhydride. The obtained resins were characterized by FTIR to confirm the conversions. LÄS MER
