  1. 6. Converting Poultry Feather Waste into Bioplastics using Green Modifying Agents

    Master-uppsats, Lunds universitet/Centrum för analys och syntes

    Författare :Marc Jirström; [2021]
    Nyckelord :polymer technology; materials science; renewable materials; Technology and Engineering;

    Sammanfattning : Handling of problematic waste material, and the use of fossil-based and non-biodegradable plastics are two major sustainability challenges. By developing solutions that convert waste material to bioplastics, it is possible to address both these issues. LÄS MER

  3. 7. Microscopy techniques for studying polymer-polymer blends

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

    Författare :Sandra Mattsson; [2019]
    Nyckelord :CLEM; correlative light and electron microscopy; correlative microscopy; fluorescence microscopy; scanning electron microscopy; phase contrast microscopy; polymer blend; morphology; super yellow; PEO; poly ethylene oxide ; CLEM; korrelativ ljus- och elektronmikroskopi; korrelativ mikroskopi; fluorescensmikroskopi; svepelektronmikroskopi; faskontrastsmikroskopi; polymerblandning; morfologi; super yellow; PEO; poly etylenoxid ;

    Sammanfattning : Semiconductors are used in many electronic applications, for example diodes, solar cells and transistors. Typically, semiconductors are inorganic materials, such as silicon and gallium arsenide, but lately more research and development has been devoted to organic semiconductors, for example semiconducting polymers.

  4. 8. Tribological Performance of Hygrothermally Aged UHMWPE Hybrid Composites

    Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Luca Palmeira Belotti; [2018]
    Nyckelord :UHMWPE; aging; polymers; tribology;

    Sammanfattning : Stricter environmental regulations and trend of decreasing cost and increasing operational efficiency are the driving forces for the improvement of the tribological performance in many different industries. For example, in the case of hydropower plants, there has been increasing research carried out to achieve oil-free stations, which would substitute the oil-based lubricants with environmentally accepted lubricants or water.

  5. 9. Block Copolymer Lithographyfor Nano-porous Oxide Thin Films

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

    Författare :Yandi Liu; [2018]
    Nyckelord :Block Copolymer; Lithography; Nanopatterning; Reactive-Ion Etching; Oxide Thin Films; Blockcopolymer; Litografi; Nanopakning; Reaktion-Jon Etsning; Oxidtunnfilmerna;

    Sammanfattning : This thesis focuses on employing a new patterning technique called block copolymer lithography to transfer the nano-porous pattern from the polymer template to the underlying oxide thin film. Nano-porous block copolymer films are produced by spin-coating polymer solution on wafers followed by annealing, UV exposure and development processes. LÄS MER

  7. 10. Measuring material properties of thin films with DIC and tearing test of laminate

    Uppsats för yrkesexamina på avancerad nivå, Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Författare :Peter Nilsson; [2017]
    Nyckelord :DIC; Thin polymer films; Laminated tearing;

    Sammanfattning : Thin polymer materials are today widely used in industry and production. An ordinary food package can have around six different layers of materials laminated together to obtain the desired protection. To obtain an efficient usage of these materials simulations are often required. LÄS MER
