Porous membranes with under-liquid dual superlyophobic properties, which are difficult to achieve because of a thermodynamic contradiction, have attracted considerable interest in the field of switchable oil/water separation. Herein, a bioinspired mesh membrane with alternating hydrophilic and hydrophobic chemical patterns on its surface that endows it with superamphiphilic and under-liquid dual superlyophobic properties is fabricated by a simple liquidus modification process. The as-prepared membrane possesses a combination of under-oil superhydrophobic and under-water superoleophobic characteristics in the absence of external stimuli. Moreover, it can effectively perform the on-demand separation of various oil/water systems, including immiscible oil/water mixtures and oil/water emulsions owing to its under-liquid dual superlyophobic properties.

Superamphiphobic and flame-retardant fabrics offer effective protection for firefighters and industrial workers operating under hazardous conditions. However, limitations in deformation resistance, wear comfort, and environmental adaptability hinder their practical applications. Here, a monolithic hierarchical macro-/micro-/nanostructure is constructed to achieve durable repellency against water and oils, even under significant deformations. This coating integrates fluorinated nanoparticles, flame retardant microparticles, and a cross-linking adhesive. Hydrogen bonding and the adhesive define the coating’s morphology, robustness, and adaptability. The coated surface exhibits an ultralow water adhesion force (0.002 mN) and excellent anti-fouling performance against extreme temperatures (100 °C, −196 °C) and corrosive liquids, including aqua regia and concentrated H 2 SO 4 . Upon fire exposure, the coating enables self-extinguishing behavior on cotton fabrics. The coated fabrics also demonstrate remarkable mechanical and UV resistance while preserving wear comfort. Overall, we achieve a balance between desirable properties and wear comfort in superamphiphobic, flame-retardant fabrics, enabling protective clothing applications previously unattainable.

Superamphiphobic and electroactive composite coating on aluminum substrate was successfully fabricated by integrating epoxy, polyaniline (PANI), fluorinated ethylene propylene , carbon nanotubes and SiO 2 nanoparticles into a two-layer coating configuration with nano/micro hierarchical surface structure. The composite coating demonstrates strong adhesion, excellent wear resistance and durable anti-wettability. The electrochemical tests demonstrated significantly enhanced anticorrosion performance by surface barrier effect of the superamphiphobic coating and redox catalytic capability of embedded electroactive PANI. The design principle of the multi-functional coatings will definitely benefit the advancement of durable anti-corrosive coatings and the achieved superior properties will promise a wider engineering applications in petroleum related industries.

It is nowadays essential to avoid electromagnetic interferes (EMI) not only in electronic equipment but also in human health with the rapid development of electronic technology. Damage or invalid in complex and harsh environments is still one of the major challenges facing the field of EMI shielding materials, but superhydrophobic surface have recently shown potential to enhance mechanical stability and chemical durability for this material. As one of the vital research directions of superwetting field, superamphiphobic surface have been often used to solve problems of other fields to improve their surface properties. Therefore, combining the superamphiphobic surface to overcome the problems of electromagnetic shielding materials is the main work of this paper. Here, a superamphiphobic surface was introduced through constructing micro-nano structure with low surface energy, which was mainly contributed from 1H,1H,2H,2H-perfluorodecyltriethoxysilane, micro-ordered array polypyrrole , multi-walled carbon nanotubes and silica. Finally, the as-prepared materials after 5000 times of kneading-releasing cycles, 60 min of ultrasonic, 50 times of abrasion by using sandpaper, 24 h of ultraviolet irradiation, and 10 h of immersion in acid, alkali and different organic solvents , still has superamphiphobic performance which means it can be used extreme environment to endow a widely applications for EMI shielding materials.
