Preparation and characterization of nanocontainers of corrosion inhibitor based on layered double hydroxides

Modified hydrotalcites for improved corrosion protection of reinforcing steel in concrete – preparation, characterization, and assessment in alkaline chloride solution

“…Since the fact that the MHTs were synthesized in alkaline solution (pH is around 10), the OH − may not be expected to exchange the intercalated inhibitors. However, previous research reported the possibility of decrease of solution pH due to the adsorption of OH − by hydrotacite‐like compounds in a solution with very high alkalinity (pH 13–14). In this research, although the synthesis of MHT was performed in a solution at pH around 10, the chloride exchange experiment was conducted in a solution with higher alkalinity (i.e., 0.1 M NaOH + 0.5 M NaCl; pH is around 13).…”

Sealing of tartaric sulfuric (TSA) anodized AA2024 with nanostructured LDH layers

“…These formed LDH was used as a promising nanocontainer for incorporation/encapsulation of corrosion inhibitors. 15,23,25,26 The main role of this LDH-based lm is the storage and release of inhibitor on demand as a result of anion-exchange between inhibiting species and corrosion-relevant anions such as chloride and/or hydroxyl anions. 27 Several authors reported that the intercalation of inhibiting anions (e.g.…”

“…vanadate, 7,28,29 etc. 26,30 ) into the LDH matrix could provide enhanced protective action. However, in spite the promising active protection the barrier properties of such layers are normally insufficient.…”

Corrosion protection of carbon steel by solvent free epoxy coating containing hydrotalcites intercalated with different organic corrosion inhibitors

“…In our previous works, hydrotalcites modified by 2-benzothiazolythio-succinic acid inhibitor (HT-BTSA) were synthesized, incorporated in a solvent based epoxy coating and applied on carbon steel [36][37][38]. The obtained results proved that HT-BTSA improved corrosion protection, adhesion and resistance to cathodic disbonding of solvent based epoxy coatings.…”
