Waterborne polymeric coating for corrosion protection has been of particular interest both in academia and industrial circles for years because of its low cost and low-volatile organic compound (VOC) emissions. However, organic coating is permeable to water and oxygen resulting in the reduction of anticorrosion properties during coating application. In this study, waterborne corrosion-resistant hydrophobic-modified alkyd resin composite coatings using fluorinated acrylate–siloxane (FASAR) and submicron-sheet zinc phosphate (Zn₃(PO₄)₂) pigment were prepared. The results of hydrophobicity, thermal, and mechanical measurements indicated that the FASAR30/5%Zn₃(PO₄)₂ had excellent performance. More importantly, the EIS and potentiodynamic polarization tests revealed that the acquired films also exhibited high anticorrosion property for carbon steel. The corrosion current density (i_corr) was 7.20 × 10⁻⁷ A cm⁻², with an inhibition efficiency of 99.92%, and a corrosion rate of 8.37 × 10⁻³ mm per year. On the other hand, the impedance modulus (Z_f = 0.01 Hz) of FASAR30/5%Zn₃(PO₄)₂ still had 5.68 × 10⁴ Ω cm² after 14-day immersion in the 3.5 wt% NaCl solution.

多年来，用于防腐​​蚀的水性聚合物涂料因其低成本和低挥发性有机化合物 (VOC) 排放而受到学术界和工业界的特别关注。然而，有机涂层可渗透水和氧气，导致涂层应用过程中的防腐性能降低。在这项研究中，使用氟化丙烯酸酯-硅氧烷 (FASAR) 和亚微米片磷酸锌 (Zn ₃ (PO ₄ ) ₂ ) 颜料制备了水性耐腐蚀疏水改性醇酸树脂复合涂料。疏水性、热和机械测量结果表明 FASAR30/5%Zn ₃ (PO ₄ ) ₂有出色的表现。更重要的是，EIS和动电位极化测试表明，所获得的薄膜还表现出对碳钢的高防腐性能。腐蚀电流密度（i _corr）为7.20×10 ^-7  A cm ^-2，缓蚀效率为99.92%，腐蚀速率为8.37×10 ^-3  mm/年。另一方面，FASAR30/5%Zn ₃ (PO ₄ ) ₂的阻抗模量( Z _f = 0.01 Hz)在3.5 wt% NaCl 溶液中浸泡14 天后仍为5.68 × 10 ⁴  Ω cm ²。
