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

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

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

    Sammanfattning : 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. LÄS MER

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

    Kandidat-uppsats, KTH/Materialvetenskap

    Författare :Moa Eklund; Amanda Olofsson Ribrant; [2023]
    Nyckelord :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.;

    Sammanfattning : 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.

    Kandidat-uppsats, KTH/Fiber- och polymerteknologi

    Författare :Anna Gardell; Maria Aspenberg; Julia Aziz; [2022]
    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

  5. 4. Lignin/Carbon Fibre Composites

    Kandidat-uppsats, KTH/Kemiteknik

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

    Sammanfattning : 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. LÄS MER

  7. 5. Ett hållbart grepp om klättring : Design av ergonomiska och hållbara klättergrepp

    Kandidat-uppsats, Högskolan i Gävle/Avdelningen för industriell ekonomi, industridesign och maskinteknik
