Polymer brushes under high load. [PDF]
PLoS ONE, 2013 Polymer coatings are frequently used to provide repulsive forces between surfaces in solution. After 25 years of design and study, a quantitative model to explain and predict repulsion under strong compression is still lacking.

Localized and structured growth of polymer brushes using ink jet printing approach [PDF]
EPJ Web of Conferences, 2022 Inkjet printing (IJP) technique has been used for the deposition of silica nanoparticles with controlled position and shape onto flexible polyethylene naphthalate (PEN) substrate. The printed silica areas have been chemically functionalized with a silane

Aqueous Lubrication with Poly(Ethylene Glycol) Brushes
Tribology Online, 2014 Hydrophilic polymer brushes constitute a man-made approach to imitating nature’s lubrication mechanisms. A polymer that has been frequently used to explore such systems is poly(ethylene glycol) (PEG).

Artificial cilia for soft and stable surface covalent immobilization of bone morphogenetic protein-2
Bioactive Materials, 2023 Preservation of growth factor sensitivity and bioactivity (e.g., bone morphogenetic protein-2 (BMP-2)) post-immobilization to tissue engineering scaffolds remains a great challenge.

Thermoresponsive micropatterned substrates for single cell studies.
PLoS ONE, 2012 We describe the design of micropatterned surfaces for single cell studies, based on thermoresponsive polymer brushes. We show that brushes made of poly(N-isopropylacrylamide) grafted at high surface density display excellent protein and cell anti ...

Switchable Friction Using Contacts of Stimulus-Responsive and Nonresponding Swollen Polymer Brushes [PDF]
, 2014 Stimulus-responsive (SR), solvated polymers can switch between an expanded state and a collapsed state via external stimuli. Using molecular dynamics simulations, I show that such SR polymers can be employed to control the frictional response between two

Ordering nanoparticles with polymer brushes [PDF]
The Journal of Chemical Physics, 2017 Ordering nanoparticles into a desired super-structure is often crucial for their technological applications. We use molecular dynamics simulations to study the assembly of nanoparticles in a polymer brush randomly grafted to a planar surface as the solvent evaporates.

Polymer Brush Friction in Cylindrical Geometries
Lubricants, 2019 Polymer brushes are outstanding lubricants that can strongly reduce wear and friction between surfaces in sliding motion. In recent decades, many researchers have put great effort in obtaining a clear understanding of the origin of the lubricating ...
