“…Recently, stretchable superhydrophobic surfaces have been widely used in wearable electronics, and mechanically sensitive sensors due to their outstanding properties of self-cleaning and being water-proof. [1][2][3] In general, stretchable superhydrophobic surfaces are composed of a flexible substrate and superhydrophobic coating. For the flexible substrates, they always suffered from low elastic modulus or poor tensile strength.…”

“…In the context of concrete materials, the exceptional water repellency and enduring structural integrity offered by PDMS present an unparalleled opportunity to revolutionize conventional construction practices [28,29]. Recent developments involving PDMS-based coatings have exhibited notable resistance against various degradation mechanisms, encompassing corrosion, fouling, and chemical attack [30,31]. For instance, Lu et al [32] successfully formulated a high-performance polymer cement-based coating by innocuously introducing PDMS, which remarkably enhanced hydrophobicity, UV-aging resistance, and resistance to saltwater immersion while maintaining favorable physical properties.…”

Calcium silicate hydrate (CSH) plays a crucial role in concrete by controlling its properties and durability. The degradation of CSH often signifies concrete damage. Polydimethylsiloxane (PDMS) is commonly used to protect concrete from sulfate corrosion; however, the comprehensive mechanistic understanding of its protective effects against CSH remains limited. Here, molecular dynamics (MD) simulations were employed to explore atomic-scale interactions between PDMS coatings and CSH in a sulfate-rich environment. Our results reveal that PDMS mitigates sulfate-induced CSH decalcification by forming a positively charged layer, ultimately reducing sulfate bonding by 83.3% compared to the blank group. Molecular structure analysis highlights key hydrogen bonding and calcium–oxygen bonding interactions that are critical for this protection. Higher polymerization stabilizes substrate adsorption, reducing surface diffusion to 33.3% of low-polymerization PDMS, thereby enhancing protection. Additionally, water molecule interactions with the CSH matrix are negatively correlated with the amount of adsorbed sulfate. Simulation results offer valuable insights into the molecular-level dynamic response of the material, contributing to a deeper understanding of the protective mechanisms of PDMS against sulfate-induced CSH degradation in concrete. These findings can guide experimenters and engineers in designing more effective protective coatings for concrete exposed to sulfate-rich environments, thereby laying a foundation for further experimental research and the development of concrete materials with enhanced durability under challenging environmental conditions.

Functionalized nano‐SiO2 is an inorganic compound that exhibits hydrophobic properties upon the addition of a silane group through a chemical reaction. This property is highly effective in surface modification for various substrates, including glass, metal, and ceramics. These surface modifications find applications in self‐cleaning, anti‐fogging coatings, and water‐repellent materials. In this work, the role of nano‐SiO2 and Hexadecyltrimethoxysilane (HDTMS) functionalized nano‐SiO2 has been synthesized successfully by the sol–gel method for coating applications. The outcomes of water contact angle (WCA), analysis, Fourier transform infrared spectroscopy (FTIR), thermal gravimetric analysis (TGA), scanning electron microscope (SEM), and transmission electron microscope (TEM) observations revealed the successful grafting of hydrophobic long‐chain alkyl groups from HDTMS onto the surface of SiO2 nanoparticles. Notably, when the ratio of SiO2 nanoparticles to HDTMS is 0.25:1, the WCA of the functionalized SiO2 nanoparticles is enhanced significantly. This value is 5.35 times greater than the initial angle of contact before the modification, leading to the achievement of a super hydrophobic property.
