Superhydrophobic coatings with remarkable water repellence have emerged as an increasingly prominent field of research the growth material engineering and coating industries. address requirements several application areas characteristics including corrosion resistance, drag reduction, anti-icing, anti-fogging, self-cleaning properties. Furthermore, range applications for superhydrophobic has been substantially broadened by inclusion key performance features such flame retardancy, thermal insulation, resistance to penetration, UV transparency, anti-reflection, many more. Numerous endeavours focused on biomimetic materials because their distinct surface wettability. To develop a long lifespan, scientists refined processes preparation selection. accomplish repellency, are usually fabricated using harmful fluorinated chemicals or synthetic polymers. Utilising derived from biomass offers sustainable alternative that uses renewable resources in order eliminate consumption these hazardous substances. This paper provides insight researches reported construction lignin, cellulose, chitosan starch along techniques used constructing coatings. study is useful resource guidance selection various biobased polymers tailored specific applications.

This research aims to evaluate the effectiveness of protective coatings in preventing corrosion steel marine environment. Electrochemical tests were performed on S355JR immersed natural seawater (Black Sea, Port Constanta) over a period 22 weeks, using electrochemical techniques such as evolution open circuit potential (OCP) and linear polarization resistance calculate Rp rate (Vcorr). The investigated surfaces included (a) blasted with Al2O3, (b) coated epoxy primer enriched zinc, (c) polyurethane paint, (d) subsequently then paint which kreutzonit particles had been added. proportion added was 2 wt% total mass paint. Subsequently, samples subjected morphological analyses cross-sectional analysis by scanning electron microscopy (SEM), topographical characterization (roughness microhardness), structural assessments (FTIR XRD), well an hydrophobicity (contact angle). results this study revealed significant differences behavior between different tested. that coating provided best protection environment during immersion.

Superamphiphobic surfaces, combining both superhydrophobic and superoleophobic properties, show tremendous potential applications in various fields. However, the complicated procedures, expensive equipment, poor mechanical robustness durability seriously limit their commercialization. In this study, superamphiphobic surfaces have been fabricated by a simple spraying method using two different nanostructures of silicon dioxide. The nanosheet silica (about 80 nm) constructed large-scale layer structure, nanospherical 30 interweaved with to form double-scale "reentrant" micronano structure. contact angle (CA) sliding (SA) were estimated be 158° 1° for water droplet, while CA SA measured 154° 3° olive oil, meeting requirement. On other hand, control that only adopted or just satisfy Owing similar chemical components silica, mixed very well uniformly dispersed, endowing whole surface same behavior. More importantly, mixture was sprayed on wet poly(amide-imide) (PAI) substrate, making them easily enter into PAI film. This unique structure is helpful improving durability. Thus, wettability nearly unaffected even though it underwent lots tests, including sandpaper abrasion, ultrasonic treatment, acid–base immersion, UV irradiation, boiling jet impact. As expected, antifouling, self-cleaning, icing delay performances, time prolonged from 55 342 s. It believed robust multifunctions antiliquid-adhesion, anticorrosion, anti-icing enormous industrial environment.
