“…Bacon et al [34] found that the coating lost the protective performance when the impedance value fell below 10 8 cm 2 . Our previous study [4][5][6] indicated that the epoxy coating below 10 7 cm 2 cannot prevent the corrosion of metals from happening under AHP. In practical application, a coated system with 10 7 cm 2 still has some protective function.…”

“…They also [5] considered that both physical and chemical properties between inorganic fillers and organic binder contribute to a bad interfacial compatibility [13]. Our previous studies indicated that a large number of defects on the coating surface such as pores were generated by the addition of inorganic fillers [4][5][6]. Moreover, high surface energy of inorganic fillers would form agglomeration which lead to the degradation of coating mechanical properties [14][15][16].…”

“…According to the survey of application of the coatings in practical deep sea environment, the coatings which showed good protective performance in shallow sea often rapidly deteriorated and lost the protective function in deep sea, at least, it is the case in China. Our prior research also revealed that deep sea environment accelerated the failure of organic coating [4][5][6]. Many surface modification technologies of the inorganic particles have been extensively employed to change the physical and chemical properties of the particle surfaces, such as surface deposition method, coupling agent method, esterification method and surface grafting method [17][18][19][20][21].…”

As maritime transport becomes increasingly important, metal corrosion results in significant economic losses. Superhydrophobic materials have significant potential for corrosion prevention. However, poor compatibility between superhydrophobic materials and resin reduces the long‐term corrosion resistance. Interfacial strengthening cells (IS‐Cells) are designed to maintain superhydrophobicity and retain active hydroxyl groups participating in resin‐curing. IS‐Cells also contribute to achieving the maze effect. A novel anti‐corrosion IS coating is fabricated by compatible IS‐Cells and epoxy. IS coatings feature smooth surfaces and vertical compactness, protecting against liquid and gaseous corrosive medium. Strong diffusion resistance and extended diffusion distance ensure long‐term corrosion resistance of IS coatings. Approximately 85 µm of IS coatings remain corrosion‐free after 112 days of immersion in the NaCl solution. The low‐frequency impedance, self‐corrosion potential, and self‐corrosion current density are 1.68 × 109 Ω cm2, −0.0708 V, and 5.38 × 10−11 A cm−2, respectively. IS coatings can also withstand 2400 h of neutral salt spray testing without corrosion in the artificial scratches. Due to the electrostatic repulsion between the hydrophobic C–F chains onto IS‐Cells and protein molecules, IS coatings maintain anti‐fouling properties after dry‐wet immersion tests in the natural marine environment for 90 days. IS coatings show great potential for marine anti‐corrosion applications.

Durability of fiber‐reinforced polyoxymethylene composites under the high hydrostatic pressure in the deep sea

The effect of hydrostatic pressure of up to 40 MPa on the seawater permeation, crystalline structure, and mechanical strength of carbon fiber and glass fiber‐reinforced polyoxymethylene (POM) composites was investigated. The experimental results reveal that hydrostatic pressure slightly promotes seawater permeation throughout the POM composites and degrades the bonding strength of the matrix–fiber interface. In the POM matrix, the seawater hydrostatic pressure does not influence the chemical stability but induces a physical chain scission process, which is characterized by linearly decreased molecular weight. The chain scissions initially entangled in the amorphous region are supposed to have sufficient mobility to join the crystalline phase. The increased crystallinity, albeit slight, together with the compress effect of hydrostatic pressure may possibly account for the stable mechanical strengths of the POM composites. © 2019 Wiley Periodicals, Inc.
