In this study, LDH microparticles intercalated with sebacate (SB) were synthesized to function as a corrosion inhibitor through on-demand release. The microparticles were characterized using scanning electron microscopy, Fourier-transform infrared spectroscopy, X-ray diffraction, and thermogravimetric analysis (TGA). TGA demonstrated that LDH has high thermal stability and that the actual SB content in LDH/SB was estimated to be between 21.2 and 27.6 wt %. The effectiveness of calcium and aluminum-based LDHs intercalated with SB as a corrosion inhibitor was evaluated on aluminum AA5005 substrates, both in bare form and coated with an acrylic layer. Accelerated weathering tests revealing a reduction of approximately 40% of the corroded area and a marked reduction in filiform corrosion during constantly high relative humidity. A dilute electrolyte cyclic fog/dry test also demonstrated a significant reduction in corrosion in dry/wet cyclic aging. The SB species demonstrated potential as a corrosion-inhibiting component under the studied conditions by enhancing the corrosion resistance of the aluminum alloy. This performance was confirmed through electrochemical characterization, including potentiodynamic polarization measurements performed using an Ag/AgCl (3 mol·L−1 KCl) reference electrode. The pitting potential (Epit ) values, referred to this reference electrode, showed an increase when SB and LDH−SB were used. The blank sample presented an Epit of 0.08 V, while the samples containing SB and LDH−SB presented Epit values of 0.50 and 0.36 V, respectively.  \n1. INTRODUCTION  \nCorrosion remains one of the most significant challenges in the longevity and durability of aluminum alloys, particularly in harsh environmental conditions.1 These alloys are widely employed across multiple industries thanks to their favorable strength-to-weight ratio, formability, and aesthetic properties. Among the various aluminum alloys, AA5005 stands out for its balanced combination of mechanical properties and moderate corrosion resistance. It is a nonheat-treatable, high-strength aluminum−magnesium alloy that offers good weldability and an attractive surface finish. Due to these characteristics, AA5005 is extensively used in architectural components, marine environments, transportation sectors, and consumer goods, where both performance and appearance are critical, especially under aggressive environmental conditions. However, their susceptibility to localized corrosion, such as pitting and crevice corrosion, limits their long-term performance without appropriate protective strategies.2  \nOrganic coatings represent one of the most widely adopted and effective strategies to enhance the durability of metallic substrates, especially aluminum alloys, in aggressive environ-  \nments. These coatings act as physical barriers, preventing the diffusion of corrosive agents toward the metal surface. However, their protective performance can degrade overtime due to mechanical damage, permeability, or environmental stresses.3 To overcome these limitations, modern protective coatings often incorporate active pigments capable of inhibiting corros","cbCaibxgIVZVR6Ya","https://ap.wps.com/l/cbCaibxgIVZVR6Ya","pdf",6761545,11,"English","# Abstract\n# Introduction","[{\"question\":\"How were sebacate-intercalated LDH microparticles prepared and verified?\",\"answer\":\"LDH microparticles intercalated with sebacate (SB) were synthesized and characterized using scanning electron microscopy, FTIR, XRD, and thermogravimetric analysis (TGA).
