“…The surface chemical bonding changes before and after treatment were further studied by FTIR (Figure 4). The 880 cm −1 absorbance, in the as-prepared coating Figure 4(a), is the symmetric stretching vibration of Si–O–Si bond [24,30]; the characteristic peak at 1180 cm −1 is a typical frequency of C–F, while the 1240 cm −1 peak is caused by (CH 3 ) 3 –Si–O and the 2980 cm −1 peak can be assigned to C–H n . Moreover, the 3680 cm −1 peak belongs to –OH/–NH 2 , which may be residuals from NH 4 OH during the synthesis of SiO 2 sphere.…”

“…The aging theory states that the higher crystalline degree is the sample, the slower the aging is. Therefore, low-temperature PL-treatment (room temperature) with a longer time can be used to create a surface with stable properties, and it has been widely used in the field of the surface modification for both catalysts and films [22][23][24]. Low-temperature PL process and its generated groups can not only remove the surface organic contaminations or impurities, but also induce surface morphological change, which can further vary the surface wettability, e.g.…”

A silica/epoxy hydrophobic coating (water contact angel (WCA) = 130°) was prepared on a glass substrate and further treated in a low-temperature plasma (PL) condition, which surprisingly resulted in an amphiphilic surface (best WCA = 3.5°, best oil CA = 5°) with excellent surface stability and without decay along with the time. We systematically studied the influences of two working gases (O 2 , Ar) and the working time of PL-treatment on the wetting behaviour (for both water and oil) and the aging effects of the PL-treated silica/epoxy coating, using SEM, FTIR-ATR, XPS and metallographic microscope. The results suggested that the stable super-amphiphilic change, causing by O 2 or Ar low-temperature PL-treatment, can be attributed to a physical smoother surface (bombed by PL-treatment) and the surface chemical state change (more polar groups, OH/NH 2 ).

In this paper, the effect of water resistance, crosslinking degree, pigments addition, and immersion time on corrosion behavior of the waterborne epoxy ester coatings with different composition in 3.5 wt.% NaCl solution have been studied by electrochemical impedance spectroscopy (EIS). Results show that the coating of higher water resistance and crosslinking degree has higher corrosion resistance. However, much higher crosslinking degree may lead to decreased water resistance of the coating, and it is necessary to minimize the content of hydrophilic groups in the waterborne coating while ensuring a qualified crosslinking degree for improving its corrosion resistance. The waterborne epoxy ester varnish coating without pigments addition degrades quickly in NaCl solution compared with the coating with pigments addition of ZnMoO4 and Zn3(PO4)2. For the corrosion evolution of waterborne epoxy ester coating in NaCl solution, it has better shielding effect at 6 h immersion. At 72 h immersion, it still has corrosion protection effect to steel substrate; the NaCl electrolyte has penetrated into the coating but has not reached the coating/substrate interface. At 120 h immersion time, NaCl electrolyte has reached the coating/steel interface, and the steel corrosion has occurred. At 240 h immersion time, serious corrosion attack has occurred on the steel substrate, and the waterborne epoxy ester coating has lost its shielding effect and corrosion protection effect to the underlying steel substrate.
