“…Detailed anti‐icing performance tests were employed to evaluate the superhydrophobic silicone rubber surfaces. [ 77 ] The results show that the deeper the pores of the superhydrophobic surface of silicone rubber, the longer it takes for the contact state between water droplets and silicone rubber surface to change. Due to the presence of air in the pores, the adhesion strength between the superhydrophobic surface and the ice layer is low.…”

Silicone rubber materials have excellent comprehensive properties and are widely used in outdoor insulation, aerospace, and other fields. Due to its low surface energy and the appearance of biomimetic superhydrophobic materials, silicone rubber has become one of the popular materials in the field of superhydrophobicity. Superhydrophobic silicone rubber materials play an irreplaceable role in a wide range of applications such as long‐distance high‐voltage power transmission and high‐speed rail transportation. In this paper, research on superhydrophobic materials, including typical fabrication methods, is summarized to provide an overview of the up‐to‐date research state and progress in detail.

“…Laser texturing of silicone rubber was also exploited to obtain superhydrophobic performance. In [ 115 ], several micro-nano combined structures were directly prepared using a 200 ns laser at a wavelength of 1064 nm. A repetition rate of 100 kHz was set, and the fluence was changed from 7.5 to 15 J/cm 2 .…”

In numerous fields such as aerospace, the environment, and energy supply, ice generation and accretion represent a severe issue. For this reason, numerous methods have been developed for ice formation to be delayed and/or to inhibit ice adhesion to the substrates. Among them, laser micro/nanostructuring of surfaces aiming to obtain superhydrophobic behavior has been taken as a starting point for engineering substrates with anti-icing properties. In this review article, the key concept of surface wettability and its relationship with anti-icing is discussed. Furthermore, a comprehensive overview of the laser strategies to obtain superhydrophobic surfaces with anti-icing behavior is provided, from direct laser writing (DLW) to laser-induced periodic surface structuring (LIPSS), and direct laser interference patterning (DLIP). Micro-/nano-texturing of several materials is reviewed, from aluminum alloys to polymeric substrates.

“…In our previous studies, a superhydrophobic silicone rubber surface by short pulse laser (nanosecond laser) processing was obtained and its anti-icing properties were also investigated. 27,28 The results show that the micro-nano structures formed by physical changes on the laser-ablated surface lead to an increased hydrophobicity and have certain advantages in improving its anti-icing performance. This article investigates various physical and chemical changes on the silicone rubber surface processed by a femtosecond laser and its time-dependent wettability changes.…”

This article demonstrates the loss and recovery in hydrophobicity of silicone rubber insulator surface processed by a femtosecond laser. The two stages of the wettability conversion were investigated. First, a rough micro/nano structure was formed on the original hydrophobic sample surface processed by the femtosecond laser, and the water contact angle on the surface was reduced from 110 to a minimum of 35 . This hydrophilicity loss was due to the increase in the hydrophilic OH groups and the reduction of the hydrophobic CH 3 groups on the surfaces. Second, the roughened samples were stored in a natural ambient environment. Over a certain storage time, the surface hydrophobicity recovered gradually and evolved into a superhydrophobic state. It was found that the migration of low molecular weight cycle and/or linear siloxane oligomers resulted in the recovery of the hydrophobicity property.Coupled with the increase of surface roughness caused by laser irradiation, the further evolution of the hydrophobicity was promoted. Moreover, the higher temperature accelerates the recovery of the surface hydrophobicity. The research on the conversion mechanism of the wettability on the silicone rubber insulator surface processed by femtosecond laser is of great significance for improving its reliability in practical applications.
