“…After the photothermal self-healing, the content of C element increased to 43.85% and the content of O element decreased to 35.82%. The elemental content was similar to that of the cotton fabric surface before etching, confirming the success of the self-healing and recovery of the surface chemistry …”

“…The N1s spectrum (Figure e) consists of two different peaks, the Ti–N bond at 396.2 eV and the Ti–N–O bond at 399.6 eV . In the Si2p spectrum (Figure f), the characteristic absorption peaks at 102.7 and 101.9 eV mainly originate from O–Si and C–Si in PDMS-SiO 2 (Figure S2, schematic diagram) . The above results indicate that the PDMS-SiO 2 hybrid and TiN were successfully loaded onto the cotton fabric, and the combined effect of both increases the roughness and finally improves the hydrophobicity of the cotton fabric.…”

“…The elemental content was similar to that of the cotton fabric surface before etching, confirming the success of the self-healing and recovery of the surface chemistry. 37 Based on the above phenomena and structural analysis discussions, the mechanism of photo-remediation of the etched SPS cotton fabric was explored (Figure 4a). The synergistic action of the PDMS-SiO 2 hybrid and TiN in the nanorough structure and the underlying surface free energy layer resulted in the formation of a thin air layer between the droplet and the SPS cotton fabric surface, reducing the adhesion between the droplet and the fabric and achieving a superhydrophobic effect.…”

“…This is due to the limited number of PDMS short chains inside the fiber, but the fabric will still recover its superhydrophobicity with continued extension of the irradiation time. Nevertheless, the fabric can repair the damaged superhydrophobic surface without complex operations such as additional heating or adjusting the ambient humidity and achieve the purpose of green energy saving by using endless sunlight …”

A sustainable and strong superhydrophobic photothermal self-healing cotton fabric (SPS cotton fabric) was prepared by the simple one-pot method using nano-titanium nitride (TiN), hydroxyl-terminated polydimethylsiloxane (HPDMS), and tetraethyl orthosilicate (TEOS). After nano-TiN is adsorbed to the cotton fabric by hydrogen bonding, HPDMS and TEOS are catalyzed by ammonia to form a PDMS-SiO 2 hybrid on the cotton fabric, and finally the SPS cotton fabric is obtained. After plasma etching, cotton fabric can quickly restore superhydrophobicity by light irradiation. The micro−nanocoating on the SPS cotton fabric can resist at least 10 sandpaper abrasion cycles and etching of acid and alkali solutions without losing its superhydrophobicity. Owing to the good water repellency, the separation efficiency of the SPS cotton fabric can reach more than 98.00% for various oil−water mixtures. Even after 10 separation cycles, the separation efficiency only decreased by 0.20%, showing potential applications for waste oil treatment.

“…Owing to the wide variety of potential morphologies of three-dimensional composite nanoparticles, it is impossible to discuss them thoroughly in this review. Nonetheless, other morphologies of three-dimensional composite nanoparticles can be reasonably conceived based on the “3M” methodology and the previous discussion ( Dai et al, 2021 ; Li et al, 2022b ; Li et al, 2022c ). For example, zero-dimensional carbon black nanoparticles and one-dimensional carbon nanotubes have been mixed to obtain conductive composite nanoparticles, and superhydrophobic materials could be obtained by mixing PDMS and the conductive composite nanoparticles in a solution and curing the PDMS ( Li et al, 2022b ).…”

Fouling, including inorganic, organic, bio-, and composite fouling seriously affects our daily life. To reduce these effects, antifouling strategies including fouling resistance, release, and degrading, have been proposed. Superhydrophobicity, the most widely used characteristic for antifouling that relies on surface wettability, can provide surfaces with antifouling abilities owing to its fouling resistance and/or release effects. PDMS shows valuable and wide applications in many fields, and due to the inherent hydrophobicity, superhydrophobicity can be achieved simply by roughening the surface of pure PDMS or its composites. In this review, we propose a versatile “3M” methodology (materials, methods, and morphologies) to guide the fabrication of superhydrophobic PDMS-based materials for antifouling applications. Regarding materials, pure PDMS, PDMS with nanoparticles, and PDMS with other materials were introduced. The available methods are discussed based on the different materials. Materials based on PDMS with nanoparticles (zero-, one-, two-, and three-dimensional nanoparticles) are discussed systematically as typical examples with different morphologies. Carefully selected materials, methods, and morphologies were reviewed in this paper, which is expected to be a helpful reference for future research on superhydrophobic PDMS-based materials for antifouling applications.

Oceanic oil spills exert enduring adverse effects on marine ecosystems and human health. In contrast to conventional cleaning methods, advanced oil sorbents present a promising technology characterized by low cost, reduced environmental impact, and exceptional hydrophobicity and oleophilic properties for efficient oil removal from seawater. Despite these advantages, the efficacy of sorbents is hindered by highly viscous oil, impeding the oil/water separation process. To overcome this limitation, solar‐driven sorbents incorporating semiconductor materials are innovatively developed, leveraging increased temperatures to enhance crude oil absorption by reducing viscosity. Herein, a comprehensive review specifically focuses on various semiconductor‐functionalized sorbents for oil spill remediation, elucidating oil weathering and traditional cleaning methods to underscore the complexities and challenges in oil cleaning processes. An in‐depth discussion about the cleaning mechanisms of sorbents and the photothermal conversion processes facilitated by semiconductors is also provided. Additionally, it explores three coupling strategies—Joule heating and solar heating, photothermal effect, and magnetic effect, as well as photothermal and photocatalysis—that offer significant advancements in oil cleanup efficiency. Concluding with forward‐looking insights, the challenges and perspectives for the next generation of ocean oil spill removal technologies are proposed at the end.
