“…This phenomenon, shown at relatively low temperatures (<600 • C) in other works about siloxane surfaces, was analysed in detail by Karapanagiotis et al, by studying the effects of thermal treatment temperature and time [41]. That phenomenon takes place because the -CH3 groups on the surface of SiO2 particles are replaced by -OH groups due to the decomposition of -CH3 groups after calcining at a high temperature [34,[41][42][43].…”

“…Using ammonia, during the hydrolysis and condensation of TEOS, silica nanoparticles (with several Si-OH) progressively generate. According with other works [34,35], the hydrolysed MTES monomers cross-condense with Si-OH groups on the surface of silica particles, and then, link them into the porous network.…”

“…As can be observed, as the curing temperature increases, the silica products show less loss of mass because they have already lost mass during the curing heating. That phenomenon takes place because the -CH 3 groups on the surface of SiO 2 particles are replaced by -OH groups due to the decomposition of -CH 3 groups after calcining at a high temperature [34,[41][42][43].…”

A super-hydrophobic surface at a high temperature (400 °C) using the sol-gel method with tetraethoxysilane (TEOS) and methyltriethoxysilane (MTES) as precursors has been obtained. The effects of the coatings’ ages, deposited times and thicknesses on the hydrophobicity of the silica coatings have been analysed. The morphology, chemical composition, thermal degradation and hydrophobicity of the resulting surfaces have been studied by scanning electron microscopy (SEM), Fourier transfer infrared spectrometer (FT-IR), Thermogravimetry (TGA) and water contact angle (WCA) measurement. The results show that an average water contact angle of 149° after been cured at 400 °C for a coating aged for 5 days, and four deposition cycles using a dipping rate of 1000 mm/min was achieved.

Inspired by the lotus leaves in nature against contaminants in the muddy environment, superhydrophobic phenomena has attracted tremendous attentions among the research communities, and triggered the researchers to fabricate an artificial superhydrophobic surface for real-time applications. In this paper, the development of bioinspired materials is combed in accordance with time evolution. Besides, the advantages/disadvantages of numerous preparations in superhydrophobic coating are discussed through the recent researches.

“…At present, the traditional antirust coating is mainly to add organic acids, inorganic acids or their salts into the film‐forming system, 11–13 so as to convert or stabilize the rust 14 . However, these additives have the disadvantages of affecting the stability, poor compatibility, and toxicity of the film‐forming system in use.…”

A phytic acid‐based surface tolerant epoxy coating was prepared, and the effect of phytic acid on the corrosion resistance of the composite coating on rusty carbon steel substrate was investigated. The results showed that the low‐frequency impedance modulus of the composite coating on rusty carbon steel could reached 108 Ω·cm2 order of magnitude after immersing for 480 h in 3.5 wt% NaCl solution. Compared with pure epoxy coating, the phytic acid‐based surface tolerant epoxy coating on the rusty substrate exhibited better corrosion resistance even if with some artificial defects in the composite coating. The protective performance of the composite coating mainly came from the formation of a stable iron phytate chelate in the reaction of phytic acid and rust. For the rusty carbon steel, the original Fe3+ on its surface was also transformed by phytic acid penetrating to the interface between the coating and the substrate. Therefore, a dense film was formed with the reaction of phytic acid and rust on the substrates, and the dense film became a part of the whole paint film, which could improve the corrosion resistance of the surface tolerant coating.
