This protective coating is made by combining Epon 828 as a polymer matrix with modified layered-double-hydroxy (LDH) nanoparticles acting as corrosion inhibitor containers. To synthesize the coatings, nitrate was intercalated into Zn-Al-LDH layers through an aqueous co-precipitation method to obtain Zn-Al LDH-NO3, and decavanadate replaced nitrate within the LDH layers through an anion exchange process to obtain Zn-Al LDH-(V10O28)6\u2212. The intercalated LDH was functionalized by silanization with (3-aminopropyl)triethoxysilane (APTES) to increase the compatibility of the LDH inhibitor nanocontainers with epoxy resin and produce a protective coating. To protect the mild steel substrate, functionalized LDH nanopowders were dispersed into the epoxy resin, mixed with a polyamide hardener (Epikure 3571), and applied and cured to the metal surface. Surface morphology, structure, and chemical composition were determined for the modified LDH nanopowders using scanning electron microscopy, energy-dispersive X-ray analysis, X-ray diffraction, infrared spectroscopy, X-ray photoelectron spectroscopy, and thermogravimetric analysis. Corrosion protection of the coating system was studied using long-term immersion testing and potentiodynamic polarization studies in a 3.5 wt.% NaCl solution.<\/jats:p>","DOI":"10.3390\/molecules29040819","type":"journal-article","created":{"date-parts":[[2024,2,12]],"date-time":"2024-02-12T06:19:59Z","timestamp":1707718799000},"page":"819","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":31,"title":["Synthesis of Silane Functionalized LDH-Modified Nanopowders to Improve Compatibility and Enhance Corrosion Protection for Epoxy Coatings"],"prefix":"10.3390","volume":"29","author":[{"given":"Alireza","family":"Aminifazl","sequence":"first","affiliation":[{"name":"Department of Chemistry, University of North Texas, 1155 Union Circle #305070, Denton, TX 76203, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Darshan Jayasinghe","family":"Karunarathne","sequence":"additional","affiliation":[{"name":"Department of Chemistry, University of North Texas, 1155 Union Circle #305070, Denton, TX 76203, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Teresa D.","family":"Golden","sequence":"additional","affiliation":[{"name":"Department of Chemistry, University of North Texas, 1155 Union Circle #305070, Denton, TX 76203, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,2,10]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Kania, H.
