A colloidal route to fabricate hierarchical sticky and non-sticky substrates

Nanoporous Monolithic Microsphere Arrays Have Anti-Adhesive Properties Independent of Humidity

“…Various methods have been employed to introduce further hierarchical structure levels. Examples include plasma structuring [12], the transfer of non-contiguously packed microsphere arrays from Langmuir troughs to flat or topographically patterned substrates [13], spraying methods [14,15], spin coating [16], pressing microspheres onto gummed tape [17], generation of nanostructured layers on micropatterned substrates [18], two-step molding combined with initiated chemical vapor deposition [19] and swelling of polyamide in acetic acid [20]. …”

Fabrication of super slippery sheet-layered and porous anodic aluminium oxide surfaces and its anticorrosion property

“…Therefore, super hydrophobic surfaces with the properties of self-cleaning [13,26], anti-ice [14,15], anti-corrosion [16,17], self-healing [18], anti-fouling [19], and anti-frost [20], are fabricated by many methods. These include hydrothermal synthesis [16,21], electrospining [22,23], and self-assembly [24,25]. However, there are still several drawbacks, such as failing to self-healing, physical damage, high cost, resistance to high pressure and repulsion of complex liquids with low contact angle hysteresis [26][27][28][29][30][31].…”

Preparation of hierarchical porous Zn-salt particles and their superhydrophobic performance

“…Several reports have indicated that low-energy surface is essential for forming the superhydrophobic performance, but surface roughness plays a more vital role for enhancing it [12][13][14][15]. Hierarchical architectures are widely used in fabricating superhydrophobic materials because they provide maximum roughness to material surfaces [5,16,17].…”
