“…Figure b shows the high-resolution C 1s spectrum of the C/P/P coating, which is deconvoluted into five peaks centered at 284.2, 284.8, 285.8, 286.6, and 291.1 eV. These five peaks correspond to C–Si, C–C(H), C–N, C–O, and −CF 2 groups, − respectively. The C–O group may result from the oil pollution caused by vacuum system of XPS equipment; the C–N and C–Si groups arise from the modified MWCNTs and PDMS, respectively; the −CF 2 group stems from the PVDF; and the C–C(H) group stems from PVDF, PDMS and modified MWCNTs.…”

Repairable superhydrophobic surfaces have promising application potential in many fields. However, so far, it is still a challenge to develop a superhydrophobic surface with repairability for multiple types of damage through a simple method. In this paper, a repairable superhydrophobic coating was obtained on various substrates by bladecoating mixtures of polydimethylsiloxane (PDMS), polyvinylidene fluoride (PVDF), and multiwalled carbon nanotubes (MWCNTs) modified with dopamine (PDA) and octadecylamine (ODA). The obtained coating has a good liquid-repellent property with a water contact angle above 150°and a water sliding angle of ∼6°and possesses an excellent absorbance (∼97%) in the wavelength range of 250−2500 nm. Due to its high absorbance, the coating displays an outstanding photothermal effect with a temperature rise of ∼65 °C under irradiation by 1.0 kW/m 2 of simulated sunlight. Furthermore, after being degraded by multiple stimuli, including plasma treatment, acid/alkali/oil immersion, sand impact, and the icing−thawing cycle, the coating can recover superhydrophobicity via sunlight irradiation, demonstrating the good photothermal-induced repairability of the coating. It can be expected that the good water-repellent property, photothermal effect, and repairability give this coating a promising prospect in practical applications.

“…The addition of an elastomeric binder has previously been shown to improve the hydrophobic and mechanical properties of nanofibrous 3D networks and has previously found application as icephobic coatings and nonwovens. [ 29–31,45–47 ] To explore SDC networks that might exhibit hydrophobic and anti‐icing properties well‐suited for applications requiring a more durable, yet porous, polymer material, [ 31,33 ] we chose to investigate PES SDCs and PES SDC/PDMS composites. PES SDCs nonwovens are highly elastic and exhibit good mechanical integrity as nonwovens evidenced by their being rolled cylindrically, folded, and bent while exhibiting high WCAs (>125°) (illustrated by the images in Figure a,b) While PS SDC sheets can similarly be handled, rolled, and folded, their decreased inter‐fiber adhesion in the bulk network is more easily fractured with the application of tensile stress compared to PES and PVOH nonwovens (Figure 1).…”

The deposition of coatings with hierarchical morphology from hydrophobic and hydrophilic polymers is a common approach for making superhydrophobic and superhydrophilic coatings. The water-repellent, water-wicking, and anti-icing coatings reported here are made from a class of materials called soft dendritic colloids (SDCs). The branched, nanofibrous SDCs are produced in suspension through nonsolvent-induced phase separation in a turbulent medium. The properties of coatings formed by drying ethanol suspensions of SDCs made of polystyrene, polyvinyl alcohol, and polyester are compared. The highly branched SDC morphology creates entangled, porous coating layers with strong physical adhesion to the substrate due to the multitude of nanofiber sub-contacts analogous to the "gecko leg effect". Polystyrene SDC coatings show excellent superhydrophobicity but weaker adhesion due to low surface energy. Alternatively, polyvinyl alcohol SDC coatings show superhydrophilicity and strong adhesion from their high surface energy. Two strategies to improve the adhesivity and cohesivity of the SDCs layers are shown effective -use of intertwined networks and of silicone droplet microbinders. The water repulsion, together with the air trapped in the blended superhydrophobic coatings also makes them effective against ice nucleation and adhesion. Finally, these SDCs make thin, flexible, and durable nonwovens with similar properties.

“…The case of materials based on PDMS with nanoparticles is different from that of pure PDMS materials because nanoparticles possess inherently rough structures that can be directly exploited to fabricate PDMS-based superhydrophobic surfaces. Nanoparticle materials can be classified by morphology into four types: zero-dimensional nanoparticles ( He et al, 2011 ; He et al, 2012 ; Zhao et al, 2015 ; Aslanidou et al, 2016 ; Selim et al, 2018a ; Davis et al, 2018 ; Liu et al, 2018 ; Saharudin et al, 2018 ; Lu et al, 2019 ; Liu et al, 2020b ; Gu et al, 2020 ; Han and Gong, 2021 ; Xiong et al, 2022a ; Rin Yu et al, 2022 ; Yu et al, 2022 ) (such as spherical silicon dioxide (SiO 2 ) ( Aslanidou et al, 2016 ; Yu et al, 2022 ), titanium dioxide (TiO 2 ) ( Liu et al, 2020b ), polypyrrole nanoparticles ( Xiong et al, 2022a ), core-shell spherical composite nanoparticles ( Selim et al, 2018a ), or hollow spherical nanoclusters ( Han and Gong, 2021 )), one-dimensional nanoparticles ( Wang et al, 2019a ; Dai et al, 2019 ; Selim et al, 2019 ; Li et al, 2021 ) (such as linear nanorods ( Selim et al, 2019 ) and carbon nanotubes (CNTs) ( Li et al, 2021 )), two-dimensional nanoparticles ( Wang et al, 2019b ; Saharudin et al, 2019 ; Li and Guo, 2020 ; Cao et al, 2021 ) (such as laminar graphene and its derivatives ( Li and Guo, 2020 ), iron oxide (Fe 3 O 4 ) nanoplates ( Cao et al, 2021 )), and three-dimensional nanoparticles (single material nanoparticles such as tetrapod-shaped zinc oxide (ZnO) ( Yamauchi et al, 2019 ) and flower-like calcium titanium (CaTiO 3 ) structures ( Wang et al, 2007 ), and composite nanoparticles ( Nine et al, 2015 ; Shi et al, 2015 ; Barthwal et al, 2020 ; Zhu et al, 2020 ; Zhang et al, 2021a ; Zhang et al, 2021b ; Wu et al, 2021 ; Selim et al, 2022a ;…”

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.
