Superlubricity, a state of near-zero friction, offers transformative potential for minimizing energy dissipation and mechanical wear. However, realizing stable superlubricity has remained challenging due to difficulties in sustaining reliable lubricant structures. In this work, we present feasible straightforward strategy that integrates ionic liquids with trace amounts low-surface-energy perfluorocarbon, yielding robust highly ordered monolayer film. This composite system achieves an unprecedented friction coefficient as low 10-4, unlocking superlubricity. Furthermore, clarify the exceptional lubrication performance arises from precise modulation adhesion forces at molecular level. Our findings not only demonstrate practical pathway but also provide fundamental insights into underlying mechanisms, guiding rational design advanced systems extraordinary durability, which are particularly suitable graphite-based microelectromechanical devices.

The majority of existing single-network ionic liquid gels (ionogels) exhibit suboptimal strength and toughness, enhanced mechanical properties have the potential to expand applications range. We present a straightforward one-step polymerization method, followed by vacuum drying dehydration treatment, preparing synergistically tough P(AB-co-HB) double-network ionogels. rigid component is constituted PAB ionogel, which polymerized from acrylamide (AM) 1-butyl-3-methylimidazole chloride ([BMIM]Cl). elastic PHB are hydroxyethyl methacrylate (HEMA) tetrafluoroborate ([BMIM]BF4). combination components significantly fracture (2401.7 ± 130 kPa), toughness (∼18.6 0.8 MJ/m3), stretchability (∼1345%) Concurrently, ionogels can readily adhere various substrates, leaving no residue or irritation on surface after removal. ionogel-fabric laminates reduce flammability fabrics, while exhibiting outstanding thermal insulation flame retardant properties.
