Sticky Yet Slippery: Molecular Ordering Reconciles Bubble‐Surface Affinity With Ultralow Friction at the Nanoscale

to ∼1.9 nm and reduces friction by additional 60%. Molecular dynamics simulations attribute this "sticky-slippery" synergy to molecular ordering and homogenization, which reorganize interfacial water molecules into a well-defined depletion layer that strengthens hydrophobic interaction; simultaneously, coherent chain tilting and reorientation during bubble sliding preserve chain order and packing density, minimizing contact line pinning and energy dissipation. These findings unveil a universal molecular mechanism that reconciles bubble affinity with ultralow friction, establishing a general framework for engineering adaptive soft interfaces with programmable wetting, adhesion, and interfacial transport properties.
