    Sammanfattning : Given the potential of ionic liquids (ILs) for batteries, supercapacitors and advanced lubricants, it is crucial to understand how electric fields affect the interfacial behaviour in IL-solvent systems and the intricate relationship between nanostructure and tribotronic properties. This thesis investigates the structural and compositional changes of ILs with different solvents at electrified interfaces. LÄS MER

  7. 5. Ionic lubricants : Molecular features and surface protection mechanisms

    Författare :Bulat Munavirov; Sergei Glavatskih; Istvan Furo; Rob Dwyer-Joyce; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ionic liquid; lubrication technology; tribology; boundary lubrication; tribofilm; friction; wear; physico-chemical interaction; diffusion NMR; jonisk vätska; smörjteknik; tribologi; gränsskiktssmörjning; tribofilm; friktion; slitage; fysikalisk-kemisk interaktion; NMR diffusometri; Machine Design; Maskinkonstruktion;

    Sammanfattning : In this thesis ionic liquids (ILs) are investigated as prospective candidates for lubrication. Three custom synthesized phosphonium orthoborate type ILs were extensively studied from the prospective of molecular structuring both in bulk and at the interface and from the prospective of their lubricating performance as neat lubricants and as additives in oils.
