    Sammanfattning : During the global pandemic of coronavirus, the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) outbreak, the world was desperately searching for simpler yet more effective solutions to stop the spread of coronavirus (COVID-19). Since no one was prepared for the fast spread of such a contagious virus, there was a shortage of proper protective solutions to stop the spread. LÄS MER

  3. 2. 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.

  4. 3. Development of corrosion resistant coatings using natural biopolymer and pollen

    Master-uppsats, KTH/Materialvetenskap

    Författare :Alessandro Armani; [2020]
    Nyckelord :;

    Sammanfattning : Corrosion is a mechanism that highly reduces the lifetime of metals in different environments, especially in water or moisture environment. The worldwide maintenance cost due to corrosion is estimated in billions of dollars per year, and actual solutions in terms of coating usually contains toxic or environmentally harmful species.

  5. 4. 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

  7. 5. Reprocessing and Characterisation of High Density Polyethylene Reinforced with Carbon Nanotubes

    Master-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Sofie Svensson; [2017]
    Nyckelord :HDPE; mechanical recycling; carbon nanotubes; nanocomposites;

    Sammanfattning : Nanokomposit innehållande högdensitetspolyeten och kolnanorör återvanns och analyseradesför att undersöka hur materialets egenskaper påverkas av återvinning. Kompositenproducerades med 3 viktprocent kolnanorör och återvanns tio gånger genom att extrudera ochmala ner materialet. Analyser gjordes efter varje cykel av extrudering. LÄS MER
