Some Comments on Hydrogel and Cartilage Contact

We discuss the origin of the low friction observed for some elastically soft materials such as hydrogels and the human cartilage When a soft elastic solid is squeezed against another solid in a fluid if the nominal contact pressure is high enough after long enough contact time the contact area percolates resulting in islands of confined fluid For charged surfaces with charges of equal

Gecko‐Inspired but Chemically Switched Friction and

Chemically switched friction nanofibrillar surfaces (SiNWAs‐PSPMA SiNWAs‐PMAA arrays) can be constructed by finely decorating ordered Si nanowire arrays with responsive polymer brushes As expected these surfaces sense humidity or pH smartly and show reversible friction switching based on swelling and shrinking of the polymer brushes which is successfully monitored by AFM in liquid

Nanohydrogel Brushes for Switchable Underwater

2019-5-24In nature living systems commonly adopt the switchable friction/adhesion mechanism during locomotion For example geckos can move on ceilings relying on the reversible attachment and detachment of their feet on substrate surfaces Inspired by this scientists have used different materials to mimic natural dynamic friction/adhesion systems

Control of surface forces through hydrated boundary

2019-12-1Introduction Solvation forces arising from the tendency of liquid molecules to cluster or structure about surfaces or surface-attached molecules can strongly modulate surface interactions and thus the behavior of high surface-to-volume systems [] A case of particular interest is that of water which forms hydration layers about charges ions or zwitterions as well as polar molecules in

Biomimetic Bidirectional Switchable Adhesive Inspired

Here by cleverly engineering asymmetric polymeric microstructures a reusable switchable gecko‐like adhesive can be fabricated yielding steady high adhesion (≈ 1 25 N/cm 2) and friction (≈ 2 8 N/cm 2) forces when actuated for "gripping" yet release easily with minimal adhesion (≈ 0 34 N/cm 2) and friction (≈ 0 38 N/cm 2) forces
