1. 1. Robust and Biocompatible Bonding of Hybrid Microfluidic Devices Using Off-Stoichiometric Thiol-ene Thermosets

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Peter Harris; [2023]
   Keywords : OSTE; OSTE ; Microfluidics; Thermoset; Bonding; Thermoplastics; Biocompatibility; OSTE; OSTE ; Mikrofluidik; Härdplast; Binding; Termoplaster; Biokompatibilitet;

   Abstract : Some of the major obstacles the microfluidics industry has yet to overcome in order to facilitate large scale manufacturing of devices are costly back-end processes. Among these, bonding presents some of the most obvious difficulties and is often associated with structural deformation and surface modification. READ MORE

3. 2. Bio-based resins for digital light processing : Mechanical and degradable properties

   University essay from KTH/Materialvetenskap

   Author : Moa Eklund; Amanda Olofsson Ribrant; [2023]
   Keywords : Digital Light Processing 3D Printing DLP ; Additive manufacturing; Bio-based; Polymer; Thermosets; Covalent Adaptable Networks CANs ; Recycling; Characterization.; Digital Light Processing 3D Printing DLP ; Additiv tillverkning; Bio-baserad; Polymer; Härdplast; Kovalenta Anpassningsbara Nätverk CANs ; Återvinning; Karaktärisering.;

   Abstract : Thermosets are appropriate materials for various applications due to benefits such as heat resistance and good mechanical properties. The disadvantages of traditional thermosets from a sustainable manufacturing perspective are that they are usually derived from fossil resources, and also have permanent cross-linked networks that are difficult to break, making them non-recyclable.

4. 3. Biobased Photocurable Resins for 3D-Printing of Self-Healable & Recyclable Thermosets

   University essay from KTH/Fiber- och polymerteknologi

   Author : Anna Gardell; Maria Aspenberg; Julia Aziz; [2022]
   Keywords : 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;

   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

5. 4. Lignin/Carbon Fibre Composites

   University essay from KTH/Kemiteknik

   Author : Ali Al Husseinat; Emma Persson; Ran Carlhamn Rasmussen; Filip Rynkiewicz; [2021]
   Keywords : Kraft lignin; Solvent fractionation; Selective allylation; Lignin based composite material; Thiol-ene thermoset;

   Abstract : The market is in great need of more environmentally friendly alternatives to fossil-based composite materials to obtain a more sustainable future. Lignin is the second most common biopolymer and is a byproduct in the pulping and paper industry. READ MORE

6. 5. 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
