Super-liquid-repellent coating on the carbon steel surface

Eco-Friendly and Safe Method of Fabricating Superhydrophobic Surfaces on Stainless Steel Substrates

“…The 1650 cm –1 absorption was due to the CO bond . C–O stretching vibrations were found at 1114 and 1400 cm –1 . , Absorptions around 1384, 3134, and 3440 cm –1 were characteristic of the O–H bond. , The FT-IR results indicated that there might have been water and hydrocarbons present on the superhydrophobic surfaces. The C–C/CC/C–H nonpolar groups impart low surface energy. − Therefore, the superhydrophobicity of the as-fabricated surface can be attributed to the presence of the micro–nanohierarchical structures (Figure ) and carbon contaminants adsorbed spontaneously with low surface energy.…”

Superoleophobic Surfaces Obtained via Hierarchical Metallic Meshes

“…Superhydrophobic and superoleophobic metallic surfaces manufactured under sophisticated experimental techniques were reported recently by various groups. ,− In the present paper, we implement an approach based on exploiting metallic meshes as a substrate, which has an obvious advantage: meshes allow for robust manufacturing of hierarchical surfaces. Indeed, the largest scale is already built in the surface, namely, the scale of the mesh itself.…”

Preparation of SiO2 resin coating with superhydrophobic wettability and anti-icing behavior analysis

“…In addition, many researchers obtain superhydrophobic surfaces by changing the surface energy parameters of coatings. 24,25 The coating prepared by spraying can be applied to most alloys and has low thermal conductivity, and spraying low surface energy substances on the surface can effectively obtain appropriate surface roughness that the surface has superhydrophobic properties economically. W. Guo 26 prepared a superhydrophobic surface with fluorinated epoxy and unmodified-nano SiO 2 and micron SiO 2 , the contact angle for water was 158.6° ± 1°.…”
