Fluorine‐Free Soft Nanocomposites for High‐Speed Liquid Impact Repellence

Advanced Functional Materials, EarlyView.
Fluorine‐free soft nanocomposite coatings are developed using silicone oil‐mediated mechanical‐stiffness control, enabling ‘dry’ liquid‐repellent surfaces that resist high‐speed water jet impacts up to ∼60 m/s. By tuning nanoparticle loading and oil content, the coatings also achieve >90% optical transparency, amphiphobicity with impact resistance to ...

Lubricating Mechanism and Lubricants in Sheet Drawing (1st Report)

Journal of the Japan Society of Precision Engineering, 1954
This paper gives an account of experimental investigation on lubrication and lubricants in sheet drawing by measuring forces involved in the working. With the apparatus which was devised by one of the authors, the drawing force, the holding force and the frictional resistance of holder surface can be simultaneously recorded on film during working ...

Polymer Infiltration Into SURMOF Channels Enables Hydrophobic and Solid‐Like Slippery Functional Thin Films

Advanced Functional Materials, EarlyView.
We report a polymer‐chain insertion strategy to fabricate pore‐threaded MOF thin films with precisely tuned surface chemistry and wettability. Grafting n‐alkane chains into the pillared layer Cu2(bdc)2(dabco) MOF thin film's vertical nanochannels enhances water stability, and induces hydrophobicity and lubricant‐free, solid‐like slippery behavior ...

Graphite lubrication mechanism under high mechanical load

, 2023
Viele tribologische Extremanwendungen wie im Vakuum, in sauren Umgebungen, bei Hochtemperaturanwendungen oder unter hoher Last sind anspruchsvoll und führen oft zum Versagen herkömmlicher flüssiger Schmierstoffe wie Öle und Fette. Für diese Fälle stellen Festschmierstoffe wie Graphit eine exzellente Alternative dar.
