Ice formation and accretion on surfaces is a serious economic issue in energy supply and transportation. Recent strategies for developing icephobic surfaces are intimately associated with superwettability. Commonly, the superwettability of icephobic materials depends on their surface roughness and chemical composition. This article critically categorizes the possible strategies to mitigate icing problems from daily life. The wettability and classical nucleation theories are used to characterize the icephobic surfaces. Thermodynamically, the advantages/disadvantages of superhydrophobic surfaces are discussed to explain icephobic behavior. The importance of elasticity, slippery liquid-infused porous surfaces (SLIPSs), amphiphilicity, antifreezing protein, organogels, and stimuli-responsive materials has been highlighted to induce icephobic performance. In addition, the design principles and mechanism to fabricate icephobic surfaces with superwettability are explored and summarized.

“…There are two basic preparation methods of silicone rubber superhydrophobic coating: 1) modifying low surface energy materials on the surface with micro nano rough structure; 2) micro nano rough structures are constructed on the surface of materials with low surface energy. Based on these two basic principles, a variety of preparation methods of silicone rubber superhydrophobic coatings, such as etching method [27][28][29][30][31][32][33], template method [34][35][36], spray-impregnation method [37][38][39][40], deposition method [41][42][43], phase separation method [21,44], layer by layer assembly method [45][46], sol-gel method [47][48][49][50], etc. Each preparation method also has its own unique characteristics and application scenarios, as shown in Table 1.…”

Silicone rubber has excellent insulation properties such as good hydrophobic mobility and anti pollution flashover performance. It plays an important role in the power system and provides an important guarantee for the reliability of power supply. However, due to the erosion of various harsh environments, especially in wet environments such as rain and snow, a large amount of dirt and water are easily attached to the surface of insulating parts. It not only reduces its surface hydrophobicity and hydrophobic mobility, but also greatly shortens its service life. There are even serious leakage current problems. Especially in the low temperature environment, a lot of snow and flashover will occur at the accessories of the insulation parts. In order to solve this problem, super hydrophobic self-cleaning coating based on silicone rubber surface came into being. The preparation principle and model of superhydrophobic self-cleaning coating on silicone rubber surface are reviewed in this paper. By comparing different preparation methods, the advantages, disadvantages and application prospects are analyzed, and the existing problems and challenges are put forward according to the existing preparation technologies, so as to lay a theoretical foundation for preparing self-cleaning coatings with excellent performance in the future.

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.
