  1. 1. Thermoset biopolymer reinforced with carbon-nanotubes

    M1-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Morteza Esmaeili; [2019]
    Nyckelord :biopolymers; bio-composites; glycerol lactic acid; carbon nanotube; reinforcement; thermoset; dispersion;

    Sammanfattning : Compared to conventional fibers, carbon nanotubes possess several significant properties, which make them as an excellent alternative reinforcement in multi-functional material industry. In this study, the possibility of dispersion of the multi-wall carbon nanotube (MWCNTs) in a thermoset bio-based resin (synthesized based on end-functionalized glycerol-lactic acid oligomers, GLA, at university of Borås) was investigated.

  3. 2. Graphene-based Coatings for Heat Exchangers

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

    Författare :Marie Långberg; [2015]
    Nyckelord :Polyaniline; graphene; materials chemistry; materialkemi; Chemistry;

    Sammanfattning : This master thesis is a part of a larger interwork between SP, KTH and Alfa Laval funded by the SIO graphene programme, which end goal is to formulate an anti-corrosion coating based on graphene or graphene related materials (GRMs). The investigation is partly based on an article “Novel anticorrosion coatings prepared from polyaniline/graphene composites” from 2012 by Chang et al in combination of knowledge acquired during a previous EU project, www.

  4. 3. Fabrication of a light-weight SOFC using ceramic fibre paper as substrate

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

    Författare :Philip Löfkvist; [2015]
    Nyckelord :inorganic chemistry; solid oxide fuel cell; unmanned aerial vehicle; high temperature heat treatment; yttria stabilized zirconia; ceramic fibre paper; catator; nickel oxide; impregnation; paste manufacturing; ultra-sonication; ball-milling; optical microscopy; materials chemistry; scanning electron microscopy; materialkemi; Technology and Engineering;

    Sammanfattning : A novel method for the fabrication of a light-weight solid oxide fuel cell (SOFC) has been evaluated at Catator. This was conducted in order to lower the weight and thus cost of an unmanned aerial vehicle. The main aim for this thesis was to achieve a thin, dense and crack-free electrolyte using a ceramic fibre paper as substrate. LÄS MER
