  1. 1. Glyoxylic-Modified Lignin for Synthesis of Smart Elastomer and Composite Materials

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Xinyi Wei; [2023]
    Nyckelord :Lignin; lignin-based elastomer; nanocomposites; Lignin; ligninbaserad elastomer; nanokompositer;

    Sammanfattning : Sustainable development has become a global goal and the utilization of bioresources is a key way to achieve this crucial goal. Glyoxylic acid-functionalized lignin (GA-lignin) is one of the novel lignin derivatives extracted from beech wood (hardwood) and has great potential to be an industrially important bioresource.

  3. 2. Flexible and recyclable electronics made from nanoreinforced silk

    Master-uppsats, KTH/Fiber- och polymerteknologi

    Författare :Marek Bukovský; [2020]
    Nyckelord :Wearable electronics; flexible electronics; silk fibroin; MXene; nanocomposites; Bärbar elektronik; flexibel elektronik; silkes fibriller; MXene; nanokompositer;

    Sammanfattning : Forskningsområdet för bärbar elektronik är fortfarande relativt ungt och det finns ett stort behov av utveckling av nya material inom området. Olika typer av kompositer är mycket intressanta och de ska uppvisa såväl hög hållfasthet som goda ledande egenskaper. LÄS MER

  4. 3. Nanomechanical properties of nanocomposite polymer layer

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Tomasz Tokarski; [2019]
    Nyckelord :Nanocomposite; nanowear; nano mechanical properties; gel trapping; atomic force microscopy;

    Sammanfattning : Interphase phenomenon gains more and more interest throughout the research community. An interphase is formed between a filler particle and a polymeric matrix, and it may constitute almost the entire volume of a nanocomposite. If the interphase have favorable mechanical properties it will thus result in a nanocomposite with such properties. LÄS MER

  5. 4. Investigation of the dielectric breakdown strength of polymer nanocomposites

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad materialvetenskap

    Författare :Mattias Karlsson; [2014]
    Nyckelord :breakdown; polyethylene;

    Sammanfattning : The aim of this thesis is to investigate the possibility of enhancing the dielectric breakdown strength (DBS) of low density polyethylene (LDPE) with addition of voltage stabilizing additives. In the first part of the thesis, the influence of various process parameters on the alternating current DBS of pure LDPE and LDPE containing either 3 or 30 wt% magnesium oxide nanoparticles was investigated.

  7. 5. NCF/Wax nano composites inspired by plant cuticles

    Uppsats för yrkesexamina på avancerad nivå, KTH/Skolan för kemivetenskap (CHE)

    Författare :Chuan Qi; [2012]
    Nyckelord :plant cuticles; wax; wax-NFC composties; biocomposites; surface modification;

    Sammanfattning : Plant cuticles are extracellular membranes covering aerial organs of plants, whose main functions rely on the protection against water loss, mechanical injury from the environment, attack of microorganism, and also regulation of gas exchange. Among the several constituents of plant cuticles, waxes are those that play an important role in their barrier properties. LÄS MER
