“…This, in turn, amplifies the adhesion strength between the ice layer and the surface. [23,24] Passive techniques for both anti-icing and de-icing, employing superhydrophobic coatings with integrated electrothermal effects, have recently captured notable attention. [25][26][27][28][29] Diverging from conventional anti-icing methods, this strategy entails the application of heat to the surface, creating a thin layer underneath the ice.…”

Superhydrophobic surfaces offer notable advantages, including markedly low water affinity and reduced ice adhesion strength. Nevertheless, their practical utility is impeded by their limited durability and vulnerability to failure in cold and humid environments. In this study, a novel approach for devising an electro‐photothermal superhydrophobic (EPS) nanocomposite coating is presented. The findings indicate that the EPS nanocomposite coating exhibits both physical and chemical self‐cleaning attributes, showcasing a synergistic interplay of superhydrophobicity, electrothermal, and photothermal characteristics. The superhydrophobic coating delays icing about four times longer than the original coating. At ambient temperatures of −20 °C, the coating stacked with an electro‐ and photo‐thermal performance de‐icing layer reduces the de‐icing time by about 5 times more than the purely photo‐thermal performance de‐icing time, and reduces the de‐icing time by about 4 times more than the purely electro‐thermal de‐icing time. Furthermore, the EPS surface demonstrates the capability to sustain temperatures above 0 °C through the photothermal effect on sunny days, utilizing both the electrothermal and photothermal effects on cloudy days, and relying on the electrothermal effect during cold nights. The research introduces a novel method for fabricating functional materials, pertinent to practical anti‐icing and de‐icing applications.

“…[11][12][13] Thus far, a variety of oil-water separation materials with multiple functions and broad application domains have been developed. [14] It is encouraging that the separation materials with attractive multiple functions such as adsorption, [15] antibacterial, [16] photocatalytic, [17,18] magnetic recovery, [19] smart convertible wettability, [20,21] and a combination of the above functions [22] are more advantageous than the conventional ones with a single function. The synergy of multiple functions can purify the complex wastewater to the desired level, so the application fields of multifunctional materials are more and wider.…”

The water pollution problem caused by large-scale industrial activity is becoming increasingly serious, which not only poses a major threat to the ecosystem and human health but also seriously impedes the green and sustainable development of modern society. It is urgent to efficiently purify stubborn wastewater containing oils and other pollutants to eliminate their harm to human and environment. Therefore, it is desirable to develop multifunctional materials that can simultaneously remove oil and various pollutants or microorganisms by filtration or absorption methods to meet the practical demand for highly effective purification of wastewater with complex components. This paper summarizes the latest research progress on the "oil

“…Mussel biomimetic materials are widely used in membrane surface modification due to their excellent hydrophilic properties and adhesion properties. – Based on the adhesion properties of 5,6-dihydroxy indoles conjugated region, dopamine, tea polyphenols, tannic acid, anthocyanin, and gallocatechin gallate were introduced on the PVDF membrane to improve its hydrophilicity. ,– Undeniably, mussel-inspired codeposition modifications can provide excellent adhesion. These methods have resulted in membrane materials with good wetting and separation properties, but preparation is time-consuming (Table ).…”

The current methods of constructing modification strategies for hydrophilic membranes are time-consuming, complex in operation, and poor in universality, which limit their application on membranes. In this work, inspired by the adhesion properties and versatility of caffeic acid (CA) and p-phenylenediamine (PPDA), a simple, rapid, and universal method was designed for the separation of oil-in-water emulsion by preparing a stable hydrophilic coating separation membrane. The preparation time of the membrane was shortened to 40 min. The developed PVDF–PCA/PPDA membrane showed superhydrophilic and underwater superoleophobic properties. When applied to petroleum ether-in-water emulsion, isooctane-in-water emulsion, and dodecane-in-water emulsion separation, the oil rejection was more than 99.0%. In the circulating separation of 10 g/L soybean oil-in-water emulsion, the oil rejection was more than 99.3%, and the highest flux was 1036 L·m–2·h–1. The prepared PVDF–PCA/PPDA membrane performed well in the separation test of oily wastewater. The proposed strategy is simple and rapid; it may become a universal method for preparing membranes with super strong antifouling properties against viscous oil and accelerate the research progress of membrane separation of oil-in-water emulsions.
