Although amphiphobic materials have attracted tremendous attention recently owing to their many important applications, there remain some critical challenges such as complex or expensive fabrications, poor long-term stability, nontransparency, etc. Herein, we develop a novel kind of amphiphobic materials—statically amphiphilic but dynamically amphiphobic fluoride-free transparent coating—through one-step reaction. The obtained transparent coating can be readily applied to different kinds of substrates including flat surfaces, curved surfaces, or inner walls of some tubes and bottles, and demonstrate excellent repellency against various high/low-surface-tension liquids and outstanding stability against external damages.

A superamphiphobic coating is usually prepared via a reduction reaction and then deposited onto the surface of the substrate. This technology is difficult to control and achieve high bond strength, which easily leads to powder shedding. To overcome this issue, electroplating technology is usually preferred for preparing adhesion coatings. However, the coating prepared using this method is usually suitable only for hard steel substrates, and not for soft substrates such as carbon brushes. Herein, we demonstrate an air spray technology for preparing anti-greasy and conductive superamphiphobic graphite-1H,1H,2H,2H-perfluorooctyltrichlorosilane–SiO2 (GPS) coatings suitable for both soft substrates (carbon brushes) and hard substrates (collector rings). The sheet resistance of the coating with 10% graphite content is 4.8 × 10−3 Ω □−1 for a 10 μm thin coating, corresponding to a resistivity of 4.8 μΩ cm. More importantly, the prepared coating has excellent liquid repellency, such as water, rapeseed oil and n-hexane. In addition, the coating has excellent anti-greasy and mechanical properties, which provide a brand-new solution for the greasy pollution in the engineering field. These advantages will enhance the application of superamphiphobic GPS coating in the fields of hydropower, wind power and transportation, and so on.

Superamphiphobic surface exhibits excellent self-cleaning and anti-fouling properties, which can be applied in many fields. However, the accumulation of non-volatile organic contaminates can make the superamphiphobicity invalid gradually. Herein, we proposed a novel design of superamphiphobic coating with photocatalytic ability to degrade organic contaminates, aiming for multiple self-cleaning surface. It was realized through a simple dip coating strategy with layered and self-assembled micro-nano reentrant structure assistant with low surface energy. The dip coating surface exhibits superamphiphobicity against a variety of liquids, even for hexadecane (with a low surface energy of 27.5 mN/m) also has a contact angle of 152.4° and sliding angle of 8.4°, respectively. Simultaneously, due to the photocatalytic degradation of accumulated organic contaminants that on the surface, the dip coating surface can effectively restore the superamphiphobicity cyclically with both experimental and real outdoor conditions. Besides, this novel strategy can be applied to a variety of substrates and exhibits excellent flexibility and good durability, which can resilience to over 500 times of abrasion, chemical reagent corrosion for over 48 h, endure high temperature at 300 °C for over 12 h, and over 1,000 times of bending or 500 times of torsions. Consequently, we convince that this photocatalytic superamphiphobic coating strategy brings a promising method for maintaining long-term self-cleaning and anti-fouling capabilities in variety of applications even in harsh environments.

Superamphiphobic materials have attracted lots of attention due to its wide applications in many fields. However, the preparation of most superamphiphobic materials was time-consuming and complicated. In this study, a durable superamphiphobic fabric was prepared by vapor–liquid sol–gel method to deposit silica with thiol (SiO2–SH) and thiol–ene click reaction to graft 1H,1H,2H,2H-heptadecafluorodecyl methacrylate (FMA). The superamphiphobic fabric can repel liquids with surface tension as low as 27.5 mN m–1. Importantly, the fabric can maintain high amphiphobicity after 15 laundry cycles, 40 tape-peeling cycles, 160 g of sand abrasion, 24 h UV irradiation, as well as immersion in acid/base solution for 12 h, 95 °C water for 6 h or 2 °C water for 24 h. What’s more, the fabric shows excellent self-cleaning and antifouling properties. After the superamphiphobic fabric was prewetted by ethanol, it shows superhydrophilicity/underwater superoleophobicity and superoleophilicity/underoil superhydrophobicity, which can be used for on-demand oil/water separation with high separation efficiency and outstanding reusability.

Since the lotus effect was reported by Barthlott and Neinhuis in 1997, superhydrophobic and superoleophobic materials have received much attention due to special rough morphology and great potential applications in self-cleaning, anti-fouling, corrosion-resistance, and other fields. However, the conventional preparation process of superamphiphobic materials is complicated, including pre- and post-treatments which are used to achieve micro-nano hierarchical structures and low surface energy. In this study, we used methyltrimethoxysilane (MTMS) and 1,1,2,2- tetrahydroperfluorodecyltrimethoxysilane (FAS-17) as precursors and successfully prepared superamphiphobic FAS-17/MTMS composite aerogel via facile sol-gel method. Three-dimensional networks and long fluorocarbon chains formed micro-nano hierarchical structures. As-prepared aerogels had water contact angle (WCA) of 153.68°, oil contact angle (OCA) of 156.28°, water sliding angle (WSA) of 3.32° and oil sliding angle (OSA) of 4.57°, suggesting excellent superamphiphobic performance. Besides external superamphiphobicity, the cross section of sample also exhibited great liquid-repellency with WCA of 160.43° and OCA of 153.43°. Moreover, although cracked into powders with particle size of 0.1 mm, aerogel sample still retained its liquid-repellency with WCA of 122.85° and OCA of 128.01°, respectively. After thermal treatment under 200 ℃ for 2 h, the aerogel sample had WCA of 152.45° and OCA of 135.67°, showing excellent thermal stability. Taking advantage of low thermal conductivity and superamphiphobic properties, superamphiphobic aerogel has potential for fabricating self-cleaning and thermal insulating materials .

To address the functional failure caused by low-surface-tension liquid wetting and adhesion in superhydrophobic materials, in this study, we constructed a bilayer coating with superamphiphobic properties using an epoxy (Ep) bonding layer and an organosilane-grafted attapulgite (OG-ATP) layer through spray-coating technique. The prepared superamphiphobic bilayer coating exhibited high contact angles (CAs) and low sliding angles (SAs) for cold water (25 °C), hot water (85 °C), glycerol, ethylene glycol, peanut oil, and even n-hexadecane (CA = 150.4 ± 0.3° and SA = 7 ± 2°) with surface tension of 27.5 mN m −1 . Surface morphology and elemental analysis confirmed the coating's unique micro-nano hierarchical structure and low surface energy characteristics. Electrochemical impedance spectroscopy (EIS) results showed that the surface charge transfer resistance ( R ct ) and low-frequency modulus (|Z| 0.01Hz ) were enhanced by 6–7 orders of magnitude compared to the bare aluminum alloy substrate. The anti-corrosion performance remained stable even after 5 days of 3.5 wt% NaCl immersion. Additionally, icing experiments with water droplets at −10 °C and −15 °C revealed a significant delay in ice formation on the substrate protected by the bilayer coating. The development of this protective material, combining superamphiphobicity, self-cleaning, corrosion resistance, and anti-icing functions, will provide advanced technological reserves in areas such as marine, aviation, transportation, and manufacturing.

Coatings with superamphiphobicity and photocatalytic degradation properties to achieve excellent self-cleaning performance have received extensive attention. Herein, TiO 2 -SiO 2 composite particles with micro-/nanoscale hierarchical structures were fabricated by hydrophobic agglomeration. The TiO 2 -SiO 2 was modified with 1H, 1H, 2H, 2H-perfluorodecyltriethoxysilane (PFDTS), and then it was sprayed onto the surfaces of substrates to obtain TiO 2 -SiO 2 /PFDTS coatings. The coating surface exhibited superamphiphobicity and low adhesion properties. The contact angles (CAs) of water, ethylene glycol, glycerol, and hexadecane on the coating surface were 163.5°, 154.6°, 157.3°, and 150.2°, respectively. The slide angles (SAs) of the above droplets on the coating surface were 0.4°, 2.7°, 1.6°, and 11.1°, respectively. In addition, 80.9 % methyl orange solution (10 ppm) was degraded by the TiO 2 -SiO 2 /PFDTS under UV irradiation in 60 min, demonstrating an excellent photocatalytic degradation performance. It also had good adaptability to different substrates, liquids with different properties, and outdoor environments. The results of a mechanistic study showed that SiO 2 and TiO 2 were connected by the carbon chains of modifiers. PFDTS and TiO 2 -SiO 2 might be combined by chemical bonds or surface carbon chains. The hierarchical structure of TiO 2 -SiO 2 and the low surface energy of PFDTS resulted in the superamphiphobic property of the TiO 2 -SiO 2 /PFDTS coating.

A durable superamphiphobic cotton fabric was obtained by coating SiO2 aerogel particles, polydimethylsiloxane (PDMS), and 1H,1H,2H,2H-perfluorooctyltriethoxysilane (PFTES) on a cotton fabric via the dip-pad-dry process. The surface morphology, chemical composition, and thermal degradation behavior characterization of the as-prepared cotton fabric (PFTES/PDMS/SiO2@Cotton fabric) were performed, respectively. It was proved that the coated cotton fabric was successfully covered with PFTES/PDMS/SiO2. The porous rough surface topology structure due to the SiO2 aerogel particles along with low surface energy because of the fluorinated chains and PDMS adhesive layer on the as-obtained PFTES/PDMS/SiO2@Cotton fabric can trap a layer of air, endowing the coated fabric durable superamphiphobicity. The prepared superamphiphobic cotton fabric with a water contact angle (WCA) of 159.0 ± 0.8° and an oil contact angle (OCA) of 154.5 ± 0.7° showed good liquid repellence for common liquids in daily life like orange juice, cola, coffee, and milk, exhibiting excellent self-cleaning and stain-resistance property. Moreover, the superamphiphobic cotton fabric possessed good durability and still maintained superamphiphobicity after mechanical abrasion for 1500 cycles or ultraviolet (UV) irradiation for 96 h. This superamphiphobic cotton fabric exhibited potential applications in various fields due to the high repellency to various liquids.

Due to the construction of complicated micro-/nanohierarchical structures, designing durable superamphiphobic Al surfaces by a simple, environmentally friendly, and fast method remains a great challenge. In this article, we used a simple and environmentally friendly technique that includes laser marking and water boiling treatment to create triple-scale micro-/nanostructures on 1060 Al surfaces. The as-prepared 1060 Al surfaces revealed excellent superamphiphobicity with low sliding angles, owing to great Cassie state stability after 1H,1H,2H,2H-perfluorodecyltriethoxysilane (FAS-17) modification. The contact angle of the water droplets reaches 160°, and that of peanut oil droplets reaches 155° on this surface. Meanwhile, this superamphiphobic Al surface also possesses excellent self-cleaning ability and oil resistance. Even when entirely immersed in oil sludge, the as-prepared Al surfaces can retain superamphiphobicity. Furthermore, the as-prepared superamphiphobic Al surface demonstrates outstanding chemical stability and endurance in a variety of application environments. In addition, the as-prepared superamphiphobic Al surface offers potential anti-icing and anti-frosting properties. Therefore, the as-prepared superamphiphobic Al surface will be a potential candidate with broad applications in aerospace, construction, and marine industries. Graphical abstract

In this study, we propose a durable superamphiphobic antifouling coating with photothermal self-repairing capability. The prepared coating comprises FS-61 fluorinated kaolin, the antibacterial agent CuS, the photothermal conversion agent polydopamine (PDA), and the adhesive polydimethylsiloxanes (PDMS). The material exhibits exceptional thermal stability in thermogravimetric tests, demonstrating its ability to withstand temperatures of up to approximately 400 °C. Contact angle measurements confirm the high repellency of the coating towards oily and aqueous liquids with surface tensions as low as 27.5 mN/m, highlighting its remarkable superamphiphobic characteristics. Furthermore, the coating demonstrates robust durability in experiments simulating external environmental damage such as water scouring and tape peeling. After 24 h of water scouring and 7 tape peelings, the contact angle of the coating with water and n-hexadecane remains above 150°. Photothermal experiments provide compelling evidence for the exceptional photothermal self-healing properties exhibited by this coating material. Additionally, it shows significant growth inhibition and anti-adhesive effects against both bacteria and fungi in antibacterial tests. Therefore, the FS-kaolin/CuS-PDA/PDMS coating demonstrates immense potential for various applications including building decoration, maintenance of oil and gas pipelines, as well as protection of ships and bridges.

Environmentally robust super-repellent and flame-retardant materials satisfying various functional necessities under harsh weather events to provide protections from fouling and burn injuries have proven challenging to attain. Here, a unique four-tier hierarchical macro/micro/nanostructure is designed and constructed by regulating the accretion of multiscale organic–inorganic hybrid building blocks using silica nanoparticles, microsized ammonium polyphosphate, fluorinated alkyl silane and fluorocarbon surfactants, leading to appreciable self-cleaning, antifouling and anti-icing properties in addition to excellent flame retardancy. The fabricated rough surface exhibits super-repellency to a variety of liquids, including synthetic blood, edible oil, hexadecane, concentrated H 2 SO 4 , and even dodecane. The hierarchy of the surface texture is found to be decisive for satisfactory liquid repellency and weather resistance. In addition, the coated fabric presents an enhanced buoyancy which could load 40.2 times its own weight in water and demonstrates a favorable icing delay time of 1168 s. Various stability tests show that the coating maintains a good nonwetting state even under harsh conditions, including mechanical abrasions, repeated washing, chemical corrosion, heat treatment, and strong ultraviolet irradiation. Thus, this work provides a feasible and sustainable strategy for constructing multifunctional protective materials used in advanced protective clothing, infrastructure and transportation facilities.
