“…For PDMS with other materials, various methods can be used to obtain superhydrophobicity, such as spin coating with PDMS and polytetrafluoroethylene (PTFE) powder ( Ruan et al, 2017 ), electrospinning to produce PDMS and poly (methyl methacrylate) (PMMA) composites ( Lu et al, 2021 ), drop casting or spray coating with PDMS and wax ( Zhao et al, 2019b ; Torun et al, 2019 ; Celik et al, 2021 ), spray coating with PDMS and starch ( Wang et al, 2021c ), preparing PDMS films with SU-8 resin ( Wu et al, 2018 ), and other methods ( Děkanovský et al, 2019 ; Pakzad et al, 2020 ; Cao et al, 2022 ; Zhao et al, 2022 ). The combined action of the used materials and methods leads to specific morphologies that result in superhydrophobicity.…”

“…Silicone- or fluoro-based polymers are the main polymeric materials used to achieve superhydrophobicity or superoleophobicity ( Dobretsov and Thomason, 2011 ), and silicone- and fluoro-based polymers with fouling release properties are suitable for achieving antifouling abilities ( Carl et al, 2012 ; Lejars et al, 2012 ; Liu et al, 2017 ; Liang et al, 2020 ). However, fluoro-based materials are expensive and may result in irreversible pollution due to fluoride toxicity ( Cao et al, 2022 ). By contrast, silicone-based polymers, such as polydimethylsiloxane (PDMS), are advantageous owing to their acceptable costs, chemical stability, biocompatibility, and weatherability ( Liu et al, 2021 ).…”

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.

“…Surfaces can be categorized according to the water contact angle (WCA), as hydrophilic (for WCA <90°) or hydrophobic (for WCA >90°) ( Li et al, 2020b ; Yang et al, 2022 ; Zhao et al, 2022 ). In particular, a surface is considered superhydrophilic or superhydrophobic when the WCA is lower than 10° or higher than 150°, respectively ( Ji et al, 2021 ; Cao et al, 2022 ; He et al, 2022 ). Furthermore, according to the anisotropy of the WCA, the surface wettability can be either isotropic or anisotropic surface wettability (ASW).…”

Porous polydimethylsiloxane (PDMS) films with special surface wettability have potential applications in the biomedical, environmental, and structural mechanical fields. However, preparing porous PDMS films with a regular surface pattern using conventional methods, such as chemical foaming or physical pore formation, is challenging. In this study, porous PDMS films with a regular surface pattern are designed and prepared using 3D printing to ensure the formation of controllable and regular physical structures. First, the effect of the surface wettability of glass substrates with different surface energies (commercial hydrophilic glass and hydrophobic glass (F-glass) obtained by treating regular glass with 1H,1H,2H,2H-perfluorooctyl-trichlorosilane) on the structural characteristics of the 3D printed PDMS filaments is investigated systematically. Additionally, the effect of the printing speed and the surface wettability of the glass substrate on the PDMS filament morphology is investigated synchronously. Next, using the F-glass substrate and an optimized printing speed, the effects of the number of printed layers on both the morphologies of the individual PDMS filaments and porous PDMS films, and the surface wettability of the films are studied. This study reveals that regularly patterned porous PDMS films with distinct structural designs but the same controllable surface wettability, such as anisotropic surface wettability and superhydrophobicity, can be easily fabricated through 3D printing. This study provides a new method for fabricating porous PDMS films with a specific surface wettability, which can potentially expand the application of porous PDMS films.

“…21 It is also possible to impart dynamic covalent bonding sites on PBzs or supramolecular interactions to produce selfhealable materials. [22][23][24] For example, self-healing by light triggered [2 + 2] cycloaddition was accomplished using coumarin functional benzoxazines. 25 Although deep light penetration into such materials is limited, these systems were shown to be capable of initiating the healing process on demand.…”
