Résumé : |
Organoclays modified by two different pillaring agents were introduced in polybenzoxazine (PBz) coatings on mild steel (MS). Both physicochemical properties and corrosion protection performance of composite coatings were fully investigated with the assistance of FTIR, XRD, AFM, SEM, and electrochemical measurements. The octadecyl quaternary ammonium-modified organoclays exhibited an exfoliated structure in polymer matrix, which benefited little in coatings’ barrier property. However, organoclays modified by dimethyl dioctadecyl quarternary ammonium induced an intercalated structure in composites, which greatly enhanced the corrosion resistance of poly(BA-aptms) with corrosion rate reduced by 3 and 4 orders of magnitude, respectively, compared to PBz and bare MS when 3 wt% of organoclays were added. |
