Intermolecular interactions between Bottlebrush Polymers boost the protection of surfaces against frictional wear
(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, ...
Bioinspired microstructures of chitosan hydrogel provide enhanced wear protection
(Royal Society of Chemistry, 2018-02-16)
We describe the fabrication of physical chitosan hydrogels exhibiting a layered structure. This bilayered structure, as shown by SEM and confocal microscopy, is composed of a thin dense superficial zone (SZ), covering a ...
Lubrication and wear protection of micro-structured hydrogels using bioinspired fluids
(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 ...
Unraveling the correlations between conformation, lubrication, and chemical stability of bottlebrush polymers at interfaces
(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 ...
Wear protection without surface modification using a synergistic mixture of molecular brushes and linear polymers
(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 ...
