“…Herein, we show that superhydrophobic coatings can also be used in an innovative way to address the increasingly significant issue of pollution caused by MPs [53]. The coating obtained in this study confirmed that the wetting properties of superhydrophobic surfaces combined with the properties of MPs can be used to remove these pollutants [54]. Further research is needed to clearly determine the physico-chemical mechanisms that lead to MPs migrating from water to oil, as well as the effects of the oil used and the different morphologies and systems in the removal of MPs from oceans, rivers and water treatment plants.…”

The pollution caused by microplastics around the world is an increasingly significant issue that has to be tackled with different methods and technologies. Here, we report a straightforward and rapid process combining electrodeposition and electrophoresis to produce a durable superhydrophobic coating on an aluminum substrate (UNS A91070) that has a static contact angle (153°), sliding angle (1°), and contact angle hysteresis (1°). Field emission scanning electron microscopy and high-resolution transmission electron microscopy showed the presence of a hierarchical structure with nanolayers that were 70 nm thick. The chemical composition was also analyzed using attenuated total reflectance-Fourier transform infrared spectroscopy and high-resolution X-ray photoelectron spectroscopy, which revealed that the hierarchical structure was composed of zinc laurate (Zn(C11H20COO)2) that decreased the surface free energy of the system. Moreover, the coating showed high durability against abrasion caused by the P1200 SiC paper due to the presence of TiO2 particles in the upper layers as well as the homogeneous chemical composition of the hierarchical structure. Finally, taking advantage of the superoleophilic properties of superhydrophobic surfaces, the ability of the coating to remove high-density polyethylene microplastics from water was studied.

“…Iron‐modified adsorbents have been engineered using various processes (e.g., chemical co‐precipitation, hydrothermal, chemical vapor deposition, calcination, and sonication) while the addition of different metals (copper, cobalt, manganese, and platinum), minerals (kaolin), and acids (phosphonic acid molecules, lauric acid) can alter the hydrophobic properties (i.e., super hydrophilic or superhydrophobic) and enhance re‐active sites/functional groups all of which results in more efficient adsorption of MPs on the surfaces of these metal‐based adsorbents (Rius‐Ayra et al. 2021; Sarcletti et al. 2021; Huang et al.…”

Environmental pollution has been one of the people’s most significant concerns for decades. In today’s industrialized and modernized society, the problem of environmental pollution has become more and more serious, directly affecting the sustainable development of each country. The unique surface properties of materials and interfaces produced by biomimetic approaches can be leveraged to create practical solutions to challenging environmental issues. Among them, superhydrophobic materials get a lot of attention because of their exceptional capacities in various environmental applications such as oil-water separation, membrane-based water purification and desalination, biofouling prevention, high-performance vapor condensation, and atmospheric water capture. This chapter reviews and discusses the fundamental principles of superhydrophobicity, recent works in preparing superhydrophobic surfaces, their potential environmental applications, and the challenges confronted in their new applications.
