Although superhydrophobic materials have attracted much research interest in anti-icing,some controversy still exists.In this re-search,we report a cost-effective method used to verify the contribution of area fraction to ice adhesion strength.We tried to partial-ly-embed silica nanoparticles into microscale fabrics of a commercial polyamide mesh.Then,the area fraction could be determined by altering the mesh size.Generally,the ice adhesion strength decreases as the area fraction decreases.An ice adhesion strength of ～1.9 kPa and a delayed freezing time of ～1048 s can be obtained.We attribute the low ice adhesion strength to the combination of superhydro-phobicity and stress concentration.The superhydrophobicity prohibits the water from penetrating into the voids of the meshes,and the small actual contact area leads to stress concentration which promotes interfacial crack propagation.Moreover,our superhydrophobic mesh simultaneously exhibits a micro-nano hierarchical structure and a partially-embedded structure.Therefore,the as-prepared super-hydrophobic mesh retained the icephobicity after 20 icing/deicing cycles,and maintained its superhydrophobicity even after 60 sandpa-per-abrasion cycles and a 220 ℃ thermal treatment.
