1. Biobased Photocurable Resins for 3D-Printing of Self-Healable & Recyclable Thermosets
Kandidat-uppsats, KTH/Fiber- och polymerteknologiSammanfattning : 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
2. Transformation of lignin into biobased thermoset
Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)Sammanfattning : 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. LÄS MER
3. Eco Friendly Composites Prepared from Lactic Acid Based Resin and Natural Fiber
Master-uppsats, Högskolan i Borås/Institutionen IngenjörshögskolanSammanfattning : 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. Synthesis and characterization of tall oil fatty acid based thermoset resin suitable for natural fiber reinforced composite
Magister-uppsats, Högskolan i Borås/Institutionen IngenjörshögskolanSammanfattning : 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
5. Mechanical and Thermal Characterizations of Biobased Thermoset Resins from Soybean Oil Reinforced with Natural Fiber Using Vacuum Injection Moulding Technique
Magister-uppsats, Högskolan i Borås/Institutionen IngenjörshögskolanSammanfattning : The aim of this research was to analyze the mechanical and thermal properties of composites andhybrid composites prepared with four types of jute fibers and two different resins; biobased thermosetresins acrylated epoxidized soybean oil (AESO) and mathacrylated anhydride modified soybean oil(MMSO). The processing technique used was vacuum injection molding (VIM). LÄS MER
