“…Several superhydrophobic surfaces have been obtained on hydrophilic materials by inducing an adequate roughness (Hosono et al, 2005; Zhu et al, 2006; Cao et al, 2007; Karlsson et al, 2010; Celia et al, 2013). The literature reveals the great interest for fundamental research and practical applications in these topics (Lai et al, 2011; Shirtcliffe et al, 2011; Yao et al, 2011; Kumar et al, 2015).…”

Porous Surface Films With Tunable Morphologies and Hydrophobic Properties Based on Block Copolymer Under the Effects of Thermal Annealing

et al. 2019

The fabrication of porous-structured polymer films with patterned surface structures has recently attracted increased interest within the material science field. In this work, a series of microstructure scale patterned polymer films were obtained via breath figure methods (BF) with hydrophobic surface films based on self-assembled diblock copolymers by atom-transfer radical polymerization (ATRP). The surface characteristics and morphological properties, pore size, roughness, thickness, and wettability of the block copolymer films was studied in response to variation of the hydrophilic co-monomer structures. A significant improvement of the quality and order of the hydrophobic films was observed in response to thermal annealing and a consequent optimization of the assembly process.

“…The surface of substrates could be compared before and after the surface modification on the basis of hardness and modulus. This test provides quantitative data with reference to the physical condition of engineered surfaces [36,120]. It is suggestible to compare the hardness as well as modulus of the fabricated coatings after performing accelerated weathering, corrosion or abrasion tests on the coatings.…”

Mechanical Durability of Engineered Superhydrophobic Surfaces for Anti-Corrosion

2018

Engineered superhydrophobic coating for anti-corrosion applications is a subject of great significance at present. However, the use of superhydrophobic coatings for anti-corrosion applications is hindered by the mechanical durability in many cases. There is a need for an understanding not only of how to fabricate such surfaces, but also of the corrosion resistance and mechanical durability of those coatings. This review discusses recent developments in the mechanical durability of superhydrophobic coatings primarily used for anti-corrosion. First, superhydrophobicity is introduced with an emphasis on different wetting models. After that, this review classifies the nanofabrication methods based on the material and methods of surface functionalization. Furthermore, the testing procedures used for the measurement of corrosion and mechanical durability are presented. Finally, the mechanical durability and anti-corrosion performance of the developed superhydrophobic coatings are discussed.

“…Various studies were carried out focused on delaying ice formation and easy removal of formed ice. Over the past decades, superhydrophobic coatings have shown good promise to repel and shed water [1][2][3][4]. Researchers working in various fields mimicked natural superhydrophobic surfaces (plants, inspects, bacteria, skin of aquatic animals etc.)…”

Among different types of anti-icing coatings, superhydrophobic coatings have attracted considerable attention due to their water repellency and low heat-transfer rate. However, condensation on superhydrophobic surfaces at low temperatures usually causes an increase in ice adhesion because of the induced wetting of micro-and nanostructures. By tuning the weight ratio of surface-modified nanoparticles to unmodified ones, five superhydrophobic coatings with different structural features at the microscale were developed. Ice-adhesion strength and ice-nucleation temperature were studied, together with the effect of moisture condensation on ice adhesion. It was found that the ice-adhesion strength and icing temperature of these coatings do not necessarily follow the same order among these surfaces because of different mechanisms involved. Surface roughness is inadequate to describe the necessary surface features that critically affect the anti-icing behavior of the coatings. Detailed topology/geometry has to be considered when designing icephobic coatings. Superhydrophobic coatings can be adopted for icephobic applications once the surface topology is carefully designed.
