Biological creatures with unique surface wettability have long served as a source of inspiration for scientists and engineers. More specifically, materials exhibiting extreme wetting properties, such as superhydrophilic and superhydrophobic surfaces, have attracted considerable attention because of their potential use in various applications, such as self-cleaning fabrics, anti-fog windows, anti-corrosive coatings, drag-reduction systems, and efficient water transportation. In particular, the engineering of surface wettability by manipulating chemical properties and structure opens emerging biomedical applications ranging from high-throughput cell culture platforms to biomedical devices. This review describes design and fabrication methods for artificial extreme wetting surfaces. Next, we introduce some of the newer and emerging biomedical applications using extreme wetting surfaces. Current challenges and future prospects of the surfaces for potential biomedical applications are also addressed.

surfaces are almost in situ grown on its bulk phase under special environment in nature. It is still a doubt what influences can the bulk phase composition and external environment make on the structures and properties of in situ growth surface, whether we can fabricate a desired superhydrophobic surface by controlling bulk phase composition and external environment and show a unique idea to synthesize multifunctional surface materials.In situ synthesis is one of the commonly used methods for fabricating superhydrophobic surfaces. [10] In contrast to the general preparation methods, such as roughening the surface of low surface energy materials or modifying the existed rough surface with low surface energy materials, [11] this method tends to be facile and easy to be extensively produced so as to realize practical applications. [12] For instance, Huang et al. reported a superhydrophobic/superoleophilic nanofiber membrane via in situ polymerization on SiO 2 fiber membrane using benzoxazine and Al 2 O 3 nanoparticles. [13] Zhang and co-workers developed a simple in situ method to fabricate a durable superhydrophobic/superoleophilic cellulose/LDH (layered double hydroxide) membrane. [14] Lai et al. reported nanosized graphite blocks with ordered honeycomb structure via in situ grown on 3D copper foam skeleton, the as-obtained coatings had a robust superhydrophobic surface. [15] However, these researches only refer to the hydrophobicity of surfaces, seldom involve the regulation of wetting state, and pay little attention to the influence of bulk phase composition and growth environment on the wettability and wetting state.In this work, by means of an easy reaction model of preparing superhydrophobic surface, the effects of the bulk phase composition and external environment on wettability and wetting state of the in situ growth surfaces were explored, trying to show a unique idea for fabricating the superhydrophobic surface with regulated adhesion by controlling bulk phase composition and external environment. Benzoxazine is a low surface energy substance with the theoretical possibility of preparing superhydrophobic surface. [16] That using fluorine-free benzoxazine as matrix model, selecting different metal chlorides to In nature, the superhydrophobic surfaces are almost in situ grown on its bulk phase under special environment. However, it is still a doubt how the bulk phase composition and external environment influence the structures and properties of in situ growth surfaces. To investigate the influence, a strategy is devised via using fluorine-free benzoxazine as matrix model, selecting different metal chlorides to change the bulk phase composition of the matrix and utilizing different curing media to control the interface growth environment. It is found interestingly that the properties of in situ growth surfaces depend strongly on its bulk phase composition and external environment, and the superhydrophobic surface with controlled adhesion could be synthesized by in situ polymerization through one-step curi...

“…Zhang et al reported heterohierarchical micro/nanostructures on Cu foils with a CA of 165 and a sliding angle of less than 2 using photolithography coupled with electrochemical deposition. 3 Although patterned micro/nanostructures have been achieved using this method to obtain superhydrophobicity surfaces, the photomasks used in photolithography are complicated and expensive, 34 limiting their further industrial applications. Femtosecond laser processing is a one-step direct maskless fabrication technique and has intrinsic advantages over traditional methods with respect to controllability and economy.…”

Surfaces with hierarchical micro/nanostructures have been widely fabricated for their extensive applications in self-cleaning, antireflection, etc. However, a flexible and highly efficient method for obtaining such surfaces remains a great challenge, especially for metals. In this paper, we propose a simple and tunable approach for fabricating a dual-functional surface with patterned hierarchical micro/nanostructure arrays. A femtosecond laser was used to remove the SiO 2 thin film, coated on the Cu substrate, masklessly and selectively. Then the arrays of micro-protrusions decorated with nanoneedles were synthesized successfully through thermal oxidation. We demonstrate that the morphology of the microprotrusions remarkably affects the surface properties, which can be flexibly tuned by controlling femtosecond laser parameters. By optimizing the laser parameters (e.g. scanning mode and laser fluence), we can achieve high performances with respect to superhydrophobicity, with a maximum contact angle of 161 and extremely low adhesion with a minimum sliding angle of less than 1.7 , thus demonstrating its self-cleaning function. In addition, antireflection properties with a minimum reflectance of less than 1% at a wavelength range of 700-800 nm can be achieved and the total reflectance can be steadily below 6% over a broad wavelength range of 600-1150 nm.
