Lotus-Leaf-Inspired Biomimetic Coatings: Different Types, Key Properties, and Applications in Infrastructures

A universal infrastructural issue is wetting of surfaces; millions dollars are invested annually for rehabilitation and maintenance infrastructures including roadways buildings to fix the damages caused by moisture frost. The biomimicry lotus leaf can provide superhydrophobic surfaces that repel water droplets, thus reducing penetration moisture, which linked with many deterioration mechanisms in infrastructures, such as steel corrosion, sulfate attack, alkali-aggregate reactions, freezing thawing. In cold-region countries, extent frost damage due components will be decreased significantly if minimized. Consequently, it greatly reduce costs infrastructures. present study was conducted explore any attempted produce biomimetic coatings. It focuses on anti-wetting characteristics (e.g., superhydrophobicity, sliding angle, contact angle), self-cleaning capability, durability, some special properties light absorbance transmission, anti-icing capacity, anti-fouling ability) lotus-leaf-inspired This also highlights potential applications coatings, particularly most abundant research across coating materials showed superhydrophobicity being well-tested while capacity durability remain among require further existing promise. addition, should validated before practical applications.
