  • Hydration forces at solid and fluid biointerfaces 

    Shrestha, Buddha R.; Banquy, Xavier (American Vacuum Society, 2016-01)
    We review the different molecular mechanisms giving rise to the repulsive hydration force between biologically relevant surfaces such as lipid bilayers and bio-ceramics. As we will show, the hydration force manifests itself in very different and ...

  • Intermolecular interactions between Bottlebrush Polymers boost the protection of surfaces against frictional wear 

    Faivre, Jimmy; Shrestha, Buddha R.; Xie, Guojun; Olszewski, Mateusz; Adibnia, Vahid; Moldovan, Florina; Montembault, Alexandra; Sudre, Guillaume; Delair, Thierry; David, Laurent; Matyjaszewski, Krzysztof; Banquy, Xavier (ACS Publications, 2018-05-30)
    Polymers exhibiting the bottlebrush (BB) architecture have excellent lubricating properties. However, to motivate their use in real life systems, they must also protect surfaces against frictional damage. In this article, we synthesized a library of ...

  • Lubrication and wear protection of micro-structured hydrogels using bioinspired fluids 

    Faivre, Jimmy; Montembault, Alexandra; Sudre, Guillaume; Shrestha, Buddha R.; Xie, Guojun; Matyjaszewski, Krzysztof; Benayoun, Stéphane; Banquy, Xavier; Delair, Thierry; David, Laurent (American Chemical Society, 2018-11-21)
    We report the fabrication and the use of a bioinspired synovial fluid acting as a lubricant fluid and anti-wear agent at soft and porous chitosan hydrogel tribopairs. This synthetic synovial fluid is composed of sodium hyaluronate (HA) and a bottle-brush ...

  • Unraveling the correlations between conformation, lubrication, and chemical stability of bottlebrush polymers at interfaces 

    Faivre, Jimmy; Shrestha, Buddha R.; Xie, Guojun; Delair, Thierry; David, Laurent; Matyjaszewski, Krzysztof; Banquy, Xavier (American Chemical Society, 2017-09-29)
    In the present study, we monitored the conformation and chemical stability of a hydrophilic bottlebrush (BB) polymer in pure water and buffered saline solutions. We correlated these parameters to lubricating and wear protecting properties. Using the ...

  • Wear protection without surface modification using a synergistic mixture of molecular brushes and linear polymers 

    Faivre, Jimmy; Shrestha, Buddha R.; Burdynska, Joanna; Xie, Guojun; Moldovan, Florina; Delair, Thierry; Benayoun, Stéphane; David, Laurent; Matyjaszewski, Krzysztof; Banquy, Xavier (American Chemical Society, 2017-01-10)
    We describe the design of lubricating and wear protecting fluids based on mixtures of bottlebrushes (BB) and linear polymers solutions. To illustrate this concept we used hyaluronic acid (HA) - a naturally occurring linear polyelectrolyte, and a water ...
