“…Therefore, silicone rubber (MVQ) was selected as the test material due to its hydrophobicity in the original form as well as its characteristics (resistance to selected groups of chemical substances: alcohols, thinned acids or bases; physiological harmlessness) [ 51 , 52 , 53 ]. In addition, the choice was determined by the available literature findings on the possibility to improve the hydrophobicity of silicone rubber through chemical and physical modification [ 30 , 31 , 33 ].…”

“…Chen et al modified a silicone rubber surface with 1064 nm wavelength nanosecond laser pulses of 1064 nm wavelength and obtained a surface with the contact angle of approximately 158° [ 30 ]. Zhang’s team [ 31 ] performed laser modification of silicone rubber surface using 50 nm pulse duration and 355 nm wavelength. Several repetitions of laser processing resulted in achieving the contact angle of the surface of approximately 155°.…”

The article presents significant results in research on creating superhydrophobic properties of materials which can be used as an interesting material for use in self-cleaning polymer protective gloves and similar applications where the superhydrophobicity plays a significant role. In this work the influence of laser surface modification of MVQ silicone rubber was investigated. The research was conducted using a nanosecond-pulsed laser at 1060 nm wavelength. After a process of laser ablation, the surface condition was examined using a SEM microscope and infrared spectroscopy. During the tests, the contact angle was checked both before and after the laser modification of samples pre-geometrised in the process of their production. The test results presented in the paper indicate that the chemical and physical modifications contribute to the change in the MVQ silicone rubber contact angle. A significant increase (by more than 30°) in the contact angle to 138° was observed. It was confirmed that surface geometrisation is not the only factor contributing to an increase in the contact angle of the analyzed material; other factors include a change in laser texturing parameters, such as mean beam power, pulse duration, scanning speed and pulse repetition frequency.

“…Pure PDMS can be roughened to obtain superhydrophobicity via replication ( Liu et al, 2006 ; Cho and Choi, 2008 ; Park et al, 2011 ; Dai et al, 2019 ; Liu et al, 2019 ; Schultz et al, 2020 ; Siddiquie et al, 2020 ), laser engraving ( Yong et al, 2013 ; Yong et al, 2017 ; Zhao et al, 2019a ; Zhang et al, 2020 ; Chen et al, 2021 ), introducing a sacrificial template ( Yu et al, 2017 ; Davis et al, 2018 ), wrinkling ( Zhao et al, 2013 ), 3D printing ( He et al, 2017 ; Chen et al, 2019 ), and other methods ( Zimmermann et al, 2008a ; Zimmermann et al, 2008b ; Artus and Seeger, 2014 ; Seo et al, 2016 ; Wang et al, 2021b ; Mazaltarim et al, 2021 ; Siddiqui et al, 2021 ; Park et al, 2022 ). As an example, for the PDMS to achieve superhydrophobicity, the replication methods use different molds, including natural morphologies (lotus leaves ( Liu et al, 2006 ), rose petals ( Dai et al, 2019 ), shark skin surfaces ( Liu et al, 2019 ), etc.…”

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.

“…Usually, superhydrophobic surfaces are defined as those with static water contact angles of >150° and sliding angles of <10°. 1–4 Due to the superhydrophobicity, the water droplet can easily move down a tilted surface and it does not stick to the surface and also, it bounces when it is dropped on the surface from a height. Such surfaces exhibit unique wettability characteristics and have attracted considerable attention because of their potential applications, which include corrosion protection, anti-icing, self-cleaning, 5 oil–water separation, 6 antifouling, 7 and microfluid transportation.…”
