Abstract
It is urgent and significant for the further development of superhydrophobic materials to exploit a facile, low-cost, scalable, and eco-friendly method for the manufacture of superhydrophobic materials with self-cleaning, antifouling, directional transportation, and other characteristics. Herein, an outstanding superhydrophobic material composed of a flexible microconvex aramid paper substrate, micron-scale cone-shaped copper, micro-nanoscale dendritic copper oxide, and hydrophobic copper stearate film has been successfully constructed through delicate architectural design and a convenient preparation approach. Based on the microstructure evolution and composition analysis results, it is revealed that the cone-shaped copper was etched into a dendritic copper oxide structure step by step from the top to bottom and from the outside to inside in an alkaline liquid environment. Moreover, by virtue of the compositional features and structural characteristics, the constructed superhydrophobic material showcased a high contact angle (CA), low sliding angle (SA), high porosity, low surface free energy, and adhesion work. Meanwhile, the dendritic microstructure analysis, the calculation of solid-liquid interfacial tension, and the force analysis of water droplets jointly revealed the mechanism of the bounce and merged bounce of water droplets. Finally, this superhydrophobic material has the functions of self-cleaning, antifouling, and directional transportation, especially by controlling the deformation of the material to realize the transportation of water droplets in a specified direction.

Abstract
Clogging generally happens to the leachate piping system, which poses a risk to the environment. A low surface energy nanocomposite is prepared to mitigate the cloggings, by adding the fluorinated acrylate polymer and hydrophobically modified nano-silica into high-density polyethylene (HDPE) substrate. The best addition of the fluorinated acrylate polymer and the nano-silica is given as 15% and 5%, to produce the composite with a low surface energy of 29.4 mJ/m2. Through the characterization of contact angle (CA), electrochemical corrosion, scanning electron microscopy (SEM) with energy dispersive X-ray spectrometer (EDS), atomic force microscope (AFM) and thermogravimetry (TG), the composite shows low wettability, good corrosion resistance and thermal stability. The surface hydrophobic property of the composite remains unchanged after being immersed in an acidic (pH = 2) and an alkaline (pH = 12) solution, indicating that the prepared composite has strong adaptability to the extreme environments. In addition, the composite shows better anti-scaling performance than that of the commercial high-density polyethylene (HDPE) and polyvinyl chloride (PVC) pipe materials by application of a dispensing leachate immersion test. The results provide insights into engineering practice for the design and manufacture of pipe materials for leachate collection and transport.

Air superhydrophilic-superoleophobic SiO 2-based coatings for recoverable oil/water separation mesh with high flux and mechanical stability. J Colloid Interface Sci 2021; 600:118-126.

Abstract
Due to the inherent differences in surface tension between water and oil, it is a challenge to fabricate air superhydrophilic-superoleophobic materials despite their promising potential in the field of oil/water separation. Herein, a facile approach is developed to fabricate air superhydrophilic-superoleophobic SiO2 coating by combination of controllable modifying SiO2 nanoparticle surface by both hydrophilic groups (i.e., -OH groups) and oleophobic groups (i.e., fluorinated groups) with constructing porous and hierarchical structures. Hydroxyl-modified SiO2 nanoparticles (NPs) are synthesized using a base-catalysed procedure in the presence of ammonia or NaOH. Chitosan quaternary ammonium salt (HACC) is introduced to bind SiO2 by forming a unique hydrogen bond between HACC and -OH, followed by adding pentadecafluorooctanoic acid (PFOA) to complex with HACC to form fluorinated groups. The SiO2 coatings are fabricated on various substrates (e.g., glass, foam and Cu mesh) by spraying procedure and characterized using SEM, FTIR, XPS, etc. The contact angles of oils (e.g., pump oil, castor oil, corn oil, hexadecane and bean oil) and water on the coatings are over 150° and close to 0°, respectively. By optimization, the representative SiO2-coated Cu mesh displayed high-efficiency of 99.2% in separating water from mixture of water/pump oil, and high penetration flux of 1.41 × 104 L·m-2 ·h-1. Besides, the coating maintains its superhydrophilic-superoleophobic properties even after 110 cycles of sandpaper abrasion or after being immersed in water for 3 h. After 20 cycles of oil/water separation, the coating retains separation efficiency up to 97.93%. This study provides a new and universal protocol to fabricate unique superwetting surfaces with effective oil/water separation performance, long-term durability and outstanding reusability.

Abstract
Multifunctional superamphiphobic cotton fabrics are in high demand. However, preparation of such fabrics is often difficult or complicated. Herein, a novel superamphiphobic fabric is constructed by a simple one-pot method with an in situ growth process. Under suitable alkaline conditions, dopamine (DA) can be oxidized to benzoquinone. Meanwhile, 3-aminopropyltriethoxysilane (APTES), 1H,1H,2H,2H-perfluorodecyltriethoxysilane (FAS-17) molecules undergo the hydrolysis reaction and bond together. Besides, benzoquinone can react with APTES by Schiff base and hollow nanoclusters can be finally obtained because of the steric hindrance effect of benzene ring and long alkyl chain. Such nanoclusters are formed on the surface of fabric, which endows the fabric with extreme liquid repellence. The effects of pH value and DA concentration on the surface morphology and lyophobic properties of the fabric are systematically studied. The water and pump oil contact angles of the superamphiphobic fabric obtained under the optimal reaction conditions can reach 160 and 151°, respectively. The lyophobicity of the fabric is maintained even after undergoing various harsh tests, showing significant durability and stability. In addition, the superamphiphobic fabric exhibits good antifouling and strong buoyancy ability. The superamphiphobic fabric can load 35 and 27.4 times its own weight in water and oil, respectively, which shows great potential in the field of functional textiles such as swimming suits, protective clothing, and life jackets in the future.

Abstract
Solid particulate pollutants such as microplastics constitute a global environmental issue in the 21st century. Many studies are exploring ways of removing these particles from marine environments such as seas and oceans. Here, we present a superhydrophobic surface obtained by combining anodisation and the liquid-phase deposition of lauric acid. The superhydrophobic surface was examined by field emission scanning electron microscopy (FE-SEM) and atomic force microscopy (AFM) to elucidate its hierarchical structure and wetting state, while time-of-flight secondary ion mass spectrometry (TOF-SIMS) and high-resolution X-ray photoelectron spectroscopy (HR-XPS) were applied to identify the chemical composition of the surface, which revealed that aluminium laurate decreased the surface free energy. As microplastics are usually found in saline water, it was important to study the anticorrosion properties of the surface. Polarisation curves of the anodised surface showed excellent anticorrosion properties in 3.5 wt% NaCl aqueous solution, which was enhanced by the superhydrophobic properties when the aluminium surface was anodised for 60 min. The functionalised surface was superhydrophobic (154°) and superoleophilic (0°). These wetting properties allowed the surface to remove microplastics from the NaCl aqueous solution with an efficiency higher than 99%. Thus, we present a novel application of a superhydrophobic and anticorrosive surface in the removal of microplastics. This has not been reported previously and provides a new scope for superwettable materials and their environmental applications.

Abstract
The development of a unique multilayer detached superhydrophobic structure inspired by biology with excellent superhydrophobic properties, extremely short rebound time, and low surface free energy has become a challenging issue. In this work, a superhydrophobic coating is prepared on the surface of Al 1060 via a fluorine-free, efficient, economical, and environment-friendly approach. First, a Ni nanocone layer is obtained from a recyclable electrodeposition solution. Then, stearic acid is prepared on the Ni nanocone layer by dip-coating technology, resulting in a special superhydrophobic surface called the "trampoline" structure, which is quite different from the Ni nanocone structure, as the substrate. The contact angle of water is 161.3°, and the sliding angle is 7°. In addition, the superhydrophobic coating with this special structure has had great achievement in adhesion work, resilience performance, porosity, corrosion resistance, and self-cleaning and antifouling performance. So far, very few reports have analyzed the performance of this special structure. To explain the bounce performance induced by this special trampoline structure, a multidimensional superhydrophobic bouncing mechanism was proposed. Furthermore, this work is expected to provide inspiration for future applications of the unique nonfluorinated trampoline structure in superhydrophobic materials.

Abstract
Scaling commonly occurs at pipe wall during landfill leachate collection and transportation, which may give rise to pipe rupture, thus posing harm to public health and environment. To prevent scaling, this study prepared a low surface energy nanocomposite by incorporating silicone-acrylate polymer and hydrophobically modified nano-SiO2 into the high-density polyethylene (HDPE) substrate. Through the characterization of contact angle, scanning electron microscopy and thermogravimetry, the results showed that the prepared composite has low wettability and surface free energy, excellent thermal stability and acid-base resistance. In addition, the prepared composite was compared with the commercial HDPE pipe material regarding their performance on anti-scaling by using an immersion test that places their samples into a simulated landfill leachate. It was apparent that the prepared composite shows better scaling resistance. The study further expects to provide insight into pipe materials design and manufacture, thus to improve landfill leachate collection and transportation.

Abstract
Basalt flakes (BFs) have been widely used in recent years as a novel anticorrosion material in the marine industry to prevent the corrosion of metal substrates. In this study, BFs were modified with 1–7‰ nano-SiO2 microspheres, and a modified BF epoxy coating was successfully prepared. Experimental results showed that the BF epoxy resin coating modified with 3‰ nano-SiO2 microspheres exhibited excellent chemical durability (surface weight loss rate of 2.2% in the alkali solution and only 1.1% in the acid solution at room temperature after 480 h), low water infiltration (water absorption of 0.72% after 480 h), and good mechanical performance (tensile strength of approximately 33.4 MPa). This study proves the feasibility of using nano-SiO2 microspheres to modify BF epoxy resin coating and enhance the chemical durability and mechanical properties provided by the coating.
