Patterned superfunctional surfaces based on a silicone nanofilament coating

Superamphiphobic surfaces

“…As is well-known, the combination of appropriate surface roughness 15 and surface chemistry is crucial to the preparation of superhydrophobic surfaces. Therefore, two steps, i.e., the generation of nanoscale roughness and the functionalization with low surface energy materials (mainly fluorinated small molecules or macromolecules), are involved.…”

“…Subsequently, the obtained textile was soaked in 3-aminopropyltriethoxysiloxane solution to generate surface amine groups which were then protonated with hydrochloric acid. The positively charged textile was then dipped 15 into a suspension of negatively charged nanosilicas, resulting in a layer of silica nanoparticles because of electrostatic attraction. On the contrary, Hsieh and coworkers 24 applied hierarchical silica sphere stacking layers to glass surface via self-assembly technique.…”

“…Research on super-antiwetting and the observation of extremely high  CA dates back to more than a century ago- CA nearly 180° was firstly achieved via coating a substrate with soot, reported by 15 Ollvier in 1907. 1 Thereafter, super-antiwetting surface with water  CA higher than ca.…”

“…16 That's why 'oils' spread quickly on a solely 100 superhydrophobic surface 15 and  CA analysis with 'oils' is needed for the characterization of superamphiphobicity. 9,15 As is clearly shown in Fig. 3 15 Whether surfaces displaying  CA > 150° for probing liquids both water and 'oils' are truly superamphiphobic remains unknown if the corresponding CAH is not determined.…”

“…9,15 As is clearly shown in Fig. 3 15 Whether surfaces displaying  CA > 150° for probing liquids both water and 'oils' are truly superamphiphobic remains unknown if the corresponding CAH is not determined. For example, despite a high  CA (ca.…”
