Nitrate layered double hydroxide (LDH) phase Zn 2 Al(OH) 6 (NO 3 )Á2H 2 O is successfully exfoliated in the presence of polyester under mild conditions using water as essential solvent and at room temperature under air. From small angle X-ray scattering spectroscopy a total exfoliation is found to be achieved using up to 10 wt % LDH, while intercalated polymer nanocomposite structures largely extended up to 14 nm are observed for loading ranging from 10 to 20 wt %. The process is found to be explained by the diffusion of the polymer chain into the interlayer host structure. Starting from an initial value of 0.89 nm, %3, 7, 10, 14, and 20 nm transient interleaved nanostructures are formed without any carbonate uptake. The collective gap distance is certainly due to a defined number of polymer chains diffusing into the LDH interstices. Similarly, starting from an aqueous polyester solution highly concentrated in LDH nitrate phase up to 50% w.w, successive dilutions yield platelet exfoliation, thus rendering a smooth chemistry process attractive for potential applications.

The incorporation of 2-hydroxyethyl phosphate (2-HEP) into layered double hydroxide (LDH) galleries results in the formation of new organic-inorganic hybrid assemblies, subsequently studied as a functionalized filler with regards to their corrosion inhibition as an epoxy-based polymer primer coating of aluminum AA 2024. Hybrid layered assemblies as well as the concomitant conveivable processes that consist of the release of interleaved 2-HEP and the uptake of corrosive Clanions were studied by X-ray diffraction. From DC polarization experiments, it is demonstrated that the anodic corrosion inhibition of 2-HEP is not impeded when the molecule is intercalated in the LDH container despite the absence of

Zinc aluminum hydrotalcite containing 2-benzothiazolythio-succinic acid (HT-BTSA) and modified by 2-aminoethyl-3-aminopropyltrimethoxysilane (APS) at different concentrations (3%, 5% and 10%). APS modified HT-BTSA (HT-BTSA-S) was incorporated in epoxy coatings at 3% concentration. The corrosion protective performance of the epoxy coatings containing HT-BTSA-S were evaluated by electrochemical impedance spectroscopy, adhesion measurement. The results showed that the presence of HT-BTSA-S improved protection performance of epoxy coating and the best protection was obtained with HT-BTSA modified with 5 % APS.
