Superhydrophobicity, a unique natural phenomenon observed in organisms such as lotus leaves and desert beetles, has inspired extensive research on biomimetic materials. Two main superhydrophobic effects have been identified: the “lotus leaf effect” and the “rose petal effect”, both showing water contact angles larger than 150°, but with differing contact angle hysteresis values. In recent years, numerous strategies have been developed to fabricate superhydrophobic materials, among which 3D printing has garnered significant attention due to its rapid, low-cost, and precise construction of complex materials in a facile way. In this minireview, we provide a comprehensive overview of biomimetic superhydrophobic materials fabricated through 3D printing, focusing on wetting regimes, fabrication techniques, including printing of diverse micro/nanostructures, post-modification, and bulk material printing, and applications ranging from liquid manipulation and oil/water separation to drag reduction. Additionally, we discuss the challenges and future research directions in this burgeoning field.

The structural defects on graphene grown on a metal substrate via chemical vapor deposition can readily stimulate severe galvanic corrosion phenomena. For any defect passivation method that can be technologically promising for superior corrosion-resistant graphene coatings, efficiency and accuracy are two critical but still challenging requirements. In this work, the authors design a rapid processing method (within just 15 min) that can accurately heal various structural defects of different types and sizes on graphene coating, where the hydrophobic 1H,1H,2H,2H-perfluorooctanethiol (PFOT) molecules are self-assembled onto the defect sites. The surface morphologies, atomic bonding states, and defect-healing mechanism are deeply understood by comprehensive experimental characterizations and first-principles calculations. Both weak physical PFOT-pristine graphene bonding and strong covalent PFOT-defect bonding are two microscopic factors that enhance defect healing efficiency and accuracy. Spatially resolved electronic and electrochemical measurements show that the defect-healing not only effectively suppresses galvanic corrosion phenomena during both short-term and long-term tests, but also well preserves the superior electronic conductivity of pristine graphene. The defect healing strategy proposed here can find its wide potential applications in the fields like electro-industry, coating, and sensors that require the graphene coatings having both superior corrosion resistance and electronic property.

In addressing issues related to defects in laser quenching technologies, this study undertakes surface passivation treatment on 2205 duplex stainless steel. The investigation explores the impact of different laser parameters on the corrosion resistance of the passive film on the steel surface. The findings may provide theoretical references for the laser passivation treatment and corrosion resistance mechanism of steel surfaces.
