The interface of ice with solids plays an exceptionally important role on a wide variety natural phenomena, such as the melting permafrost, sliding glaciers or frost heaving, well many technological applications windmills, car tires, aircrafts. In this work, we perform systematic computer simulation study premelting and explore thickness structure quasi-liquid layers formed at substrates different hydrophilicities. Our shows that interfacial occurs systematically neutral whatever hydrophilicity, forming films limited for contact angles larger than ca. 50° but exhibiting complete smaller angles. Contrary to most experimental studies, focus not only behavior temperature, also pressure, which is matter relevance in situations friction. cast within rigorous framework surface thermodynamics, allows us show film function single thermodynamic variable. By token are able relate properties measured along isobar, arbitrary temperature pressure. results exploited adhesion, view understanding icephobicity. We find adhesion strength atomically smooth surfaces 1 2 orders magnitude those found experiments, conjecture reason substrate roughness presence organic adsorbents. theoretical exploit our order gain insight into heterogeneous nucleation. apolar hydrophilicity unlikely nucleators, too large conspires against Furthermore, statistical-thermodynamic shed light nature intermolecular forces promoting premelting, provide model predict layer substrate's great potential fields ranging from earth sciences aircraft engineering.

Icephobicity encompasses a multifaceted definition that necessitates evaluations across various scales, from single droplets to larger ice specimens. The predominant method for evaluating icephobicity performance is adhesion strength (IAS) testing. Multiple geometries and scales testing are proposed. conventional key parameter derived this test analysis the peak detachment force value, which subsequently converted IAS (stress). Recent studies raise questions regarding approach challenge its adequacy comprehensive assessment. To achieve more profound understanding of phenomena involved, study utilizes three distinct benches, all in horizontal shear geometry but under varying conditions. findings indicate values do not necessarily reflect actual behavior. However, versus time evolution (obtained force–time plots) can provide valuable insights into icephobicity, including viscoelastic response coatings underlying failure mechanisms. beneficial aspects additionally validated context investigating coating durability through consecutive (icing/ice detachment) cycles, wherein methodologies, such as wetting morphological parameters, fail capture deterioration.
