CORROSION INHIBITION OF CARBON STEEL BY LDH/GO HYBRID INTERCALATED WITH 2-BENZOTHIAZOLYTHIO-SUCCINIC ACID

Nguyen Thuy Duong

Abstract


Layered double hydroxide/graphene oxide hybrid (LDH/GO) intercalated with corrosion inhibitor 2-benzothiazolylthio-succinic acid (BTSA) was prepared using co-precipitation method. The synthesized LDH/GO-BTSA was characterized by FTIR, XRD and SEM. The inhibitive action of LDH/GO-BTSA on carbon steel was evaluated and compared with LDH-BTSA by electrochemical measurement. It was shown that the GO and BTSA were intercalated in LDH structure. The obtained results showed that LDH/GO-BTSA is anodic corrosion inhibitors, and the inhibition efficiency was 94 % at concentration of 1 g/l.
