    Abstract : 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. READ MORE

  3. 2. Transformation of lignin into biobased thermoset

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Linnea Cederholm; [2018]
    Keywords : lignin; microwave heating; solvolysis; biobased thermoset; lignin; mikrovågsbaserad teknik; solvolys; biobaserad härdplast;

    Abstract : Combined microwave assisted extraction/degradation of technical lignin in green solvents was successfully employed to generate polyphenolic oligomers with lower Mw than the starting material. For Lignoboost, the highest liquid yield (65 %) was obtained in 20 min at 160 °C using ethanol as solvent. READ MORE

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

    University essay from Högskolan i Borås/Institutionen Ingenjörshögskolan

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

    Abstract : 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.

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

    University essay from Högskolan i Borås/Institutionen Ingenjörshögskolan

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

    Abstract : 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. READ MORE

  6. 5. Mechanical and Thermal Characterizations of Biobased Thermoset Resins from Soybean Oil Reinforced with Natural Fiber Using Vacuum Injection Moulding Technique

    University essay from Högskolan i Borås/Institutionen Ingenjörshögskolan
