To address the challenges of equipment icing and corrosion in outdoor industrial applications, particularly the self-cleaning, anti-icing, and anti-corrosion needs of off-road vehicle chassis systems, this study employs a simple and efficient one-step spray coating method to develop a durable superhydrophobic coating. The coating exhibits excellent anti-icing capabilities and long-term corrosion resistance. Its micro-nano structure endows it with outstanding hydrophobicity, with a contact angle of 163.8°± 3.6° and a sliding angle of 2.9°± 0.2°. The superhydrophobic property of the coating significantly prolongs the freezing time of water droplets, reaching 567.2 seconds. Furthermore, the coating maintained exceptional waterproof performance during tests of mechanical abrasion, anti-corrosion, anti-fouling, and thermal stability. Even after 25 cycles of abrasive wear and exposure to harsh corrosive environments, its performance remained stable. Electrochemical tests showed that the corrosion current density of the superhydrophobic coating was only 2.74 × 10 −8 A/cm 2 , which is three orders of magnitude lower than the corrosion current density 2.474 × 10 −5 A/cm 2 of bare aluminum alloy, achieving a corrosion inhibition efficiency of up to 99.88 %, demonstrating its remarkable anti-corrosion properties.

Despite a wealth of information on removal of the microplastics (MPs) in wastewater treatment plants (WWTPs), little attention has been paid to how wastewater treatment process affect the MP physicochemical and adsorption characteristics. In this study, changes in physicochemical property of three MPs, i.e. polyamide (PA), polyethylene (PE) and polystyrene (PS) through the wastewater pipeline, grit and biological aeration tanks were investigated. The results show that compared with virgin MPs, the treated MPs have higher specific surface area and O content, and lower C and H contents, and glass transition temperature , implying that the three treatments cause the chain scission and oxidation of the MPs. Cd adsorption capacities of the MPs are higher than the corresponding virgin MPs after sulfidation in the pipeline (SWPN) and biological treatment in aeration tank (BTAT). Pearson correlation analysis shows that the increase is mainly resulted from the enhancement of the O-containing groups on the MPs. However, Cd adsorption capacities of the MPs decrease after mechanical abrasion in grit tank (MAGT), corresponding to the decrease in carbonyl index. Two dimensional FTIR correlation spectroscopy demonstrates that the N H bond in the PA plays a more important role than C H bond in the adsorption of Cd, but only change of the C H bond is found in the PE and PS. The findings provide new insights into the effect of WWTPs on the MP aging and physicochemical characteristics.

A superhydrophobic and self-cleaning photoluminescent film is developed by creating hierarchical micro-/nano-structures on soy protein film surface with hydrophobic nanoparticles. The functional protein film can resist strong acid/alkaline, organic solvents and slight mechanical abrasion without losing light-emitting and self-cleaning properties. Such film can be applied in some extreme environments for long-term outdoor service.

With an increase in marine oil pollution, efficient remediation strategies are required to completely remove the oily wastewater. The construction of self-healing coatings with high separation efficiency has become a hot research topic. In this study, the hybrid coatings of nano-silica synergized with self-healing silicon elastomer were prepared on polyethylene terephthalate (PET) fabrics by two combination strategies. Different combination strategies conferred various bonding states between the nanoparticles and the elastomer, affecting the hydrophobicity and stability of the materials. Self-healing silicon elastomer was prepared based on polydimethylsiloxane (PDMS) crosslinked by iron-based coordination. The prepared hybrid fabrics exhibited high hydrophobicity with a water contact angle (WCA) of 145˚, and could maintain the hydrophobic properties after 20 cycles of mechanical abrasion. It realized 97% separation efficiency of multiple types of oil-water solution, even severe mechanical abrasion occurred, which still basically returned to the initial level after self-healing.

The application of pH-responsive superwetting materials receives increasing attention in oil/water separation. In this work, a mussel inspired robust surface coating fabricated with dopamine, copolymer PDMAEMA- co -PHEMA- co -PHFBMA (PDHH) and SiO 2 nanoparticles (DPS) was formed on stainless steel mesh to perform multiple repeatable oil/water separation. Herein, dopamine was chosen to provide strong adhesion strength and durability, endowing the mesh excellent stability in harsh environments, such as mechanical abrasion, acid/alkali immersion and UV irradiation. In virtue of pH stimulation, the as-prepared mesh can be reversibly switched between superhydrophobicity and superhydrophilicity. Moreover, the mesh possesses remarkable oil/water separation efficiency (SE) (≥98%) and desirable recyclability. An oil collector prepared by the mesh and kapok fiber showed good oil absorption capability in the range of 39.67–79.56 g/g. The facile and inexpensive preparation of the durable separation device enables it promising in actual oil/water separation. Graphic abstract

Traditional superhydrophobic materials for oil/water separation not only depend on nonrenewable feedstocks but also lead to secondary environmental pollutions after discarding, due to the presence of inorganic nanoparticles and toxic fluorine-containing chemicals. Herein, we report a fully sustainable, nanoparticle-free, and fluorine-free superhydrophobic cotton fabric (CF) fabricated via an eco-friendly method, that is, roughness creation by enzyme etching followed by surface coating with an epoxidized soybean oil thermoset and subsequent low surface energy modification with stearic acid. The superhydrophobic CF exhibited excellent durability with surface superhydrophobicity surviving from mechanical abrasion, tape peeling, ultrasonication, chemical resistance, and low/high temperature treatment, due to the enzyme etching-induced stable surface structure with covalently linked low-energy substance. The superhydrophobic CF showed excellent oil/water separation performance with a high separation efficiency and high oil flux. With outstanding mechanical robustness, chemical and environmental resistances, and excellent oil/water separation performance, the fully sustainable superhydrophobic CF can be applied as an environmentally friendly substitute to nonrenewable and harmful chemicals containing oil/water separation materials.

Surface hydrophobicity is generally created by lower surface energy materials. However, it is predictable. Simultaneously, it is rare to construct a self-healing surface hydrophobicity using hydrophilic materials, which is an emerging and significant aspect. Herein, we for the first time fabricated the unpredictable surface hydrophobicity on the cotton fabric surface by utilizing chitosan and tannic acid (labelled as Cot@PTA@PTA-CS), in which chitosan played the decisive role. Interestingly, the surface hydrophobicity of Cot@PTA@PTA-CS could be recovered under the heating treatment. Notably, using the hydrophilic materials realizes the unpredictable surface hydrophobicity with self-healing characteristics, which is an advanced work in contrast to the conventional predictable surface hydrophobicity created by fluorine-free hydrophobic or fluorinated materials. Then, Cot@PTA@PTA-CS was treated with polydimethylsiloxane to obtain surface superhydrophobicity, regarded as Cot@PTA@PTA-CS@PDMS. Cot@PTA@PTA-CS@PDMS and Cot@PTA@PTA-CS all exhibited good hydrophobicity after mechanical abrasion. Moreover, Cot@PTA@PTA-CS@PDMS exhibited good repellency to 95 °C water, diiodomethane, ethylene glycol, and dimethyl sulfoxide. So, the surface free energies of modified cotton fabrics were calculated. Besides, the modified cotton fabrics also possessed excellent UV resistance, anti-oxidation activity, photothermal effect, and self-cleaning. Finally, Cot@PTA@PTA-CS@PDMS was used for the high-efficient oil/water separation. Briefly, this work provides a novel and feasible strategy for creating unpredictable surface hydrophobicity with self-healing performance by chitosan and tannic acid, inspiring more scholars to fabricate hydrophobic surface by hydrophilic materials.
