“…Figure 2 also shows a reference spectrum (black) of a drop of MBT solution put on an in-house developed SERS probe containing finely dispersed silver nanoparticles. The peaks are slightly shifted because of the different substrate, but coincide with those reported in the literature (Yang et al, 2008). An aqueous solution of MLDH powder was also put directly on HDG and the Ag-SERS probe.…”

This article describes a self-healing coating for corrosion protection of metals, which combines two different types of self-healing mechanisms in one coating with multiple-healing functionality. 2-Mercaptobenzothiazole (MBT) was loaded into layered double hydroxide (LDH) carriers that were mixed into an acrylated polycaprolactone polyurethane-based shape-recovery coating and applied on hot-dip galvanized steel (HDG). The effect of triggered release of MBT on the protection of HDG became visible when samples with manually applied defects in the coating were immersed in 0.05 M NaCl solution (first, autonomous-healing mechanism). The shape recovery (second, non-autonomous-healing mechanism) was triggered by heating the samples for 2 min to 60°C. SEM-EDX and Raman spectroscopy proved the presence of MBT in the LDH, in the MBT-loaded LDH in the coating and the released MBT on the HDG surface in the damaged area after being in contact with a solution containing corrosive ions. Electrochemical impedance spectroscopy and scanning vibrating electrode technique demonstrate the corrosion protection effect of MBT in the coating with a defect and the restoration of the barrier properties of the coating after defect closure. This way, the independent mechanisms of this multi-action self-healing coating could be demonstrated.

“…It is also known as an accelerator for rubber vulcanization [8], antioxidant [9] and antiseptic [10]. Anticorrosive application of MBT and its derivatives was studied for copper and copper alloys [11][12][13][14][15][16][17][18][19][20][21], zinc and silver [19,22]. According to [23], MBT can be a good inhibitor for mild steel in a wide range of phosphoric acid concentrations.…”

The electrochemical behavior of copper and zinc in neutral (рН 7.4) borate buffer solution with addition of 0.5 M NaCl and the effect of 2-merсaptobenzothiazole (MBT) on the electrochemical processes and adsorption on these metals has been studied by means of electrochemistry and X-ray photoelectron spectroscopy (XPS). The formation of MBTmetal cation complex films on copper and zinc surface has been shown. The effect of corrosive media composition and time-dependent relations of nanoscale film growth on the surface of the metals investigated have been determined. It was assumed that adsorbed MBT anion forms M(MBT) х , a polymeric complex where M = Cu + (x = 1) or Zn 2+ (x = 2).

“…Contributions from the S-S vibration signals of MBT dimers cannot be ruled out, as well. Peaks in the area between around 1007 cm À1 and 1048 cm À1 were attrib- uted to thiazole, N-H rocking, C-H-rocking, C-H-deformation, C-C-C deformation and C-C and C-H scissoring vibrations [28,40,52]. And the intense peak at 1389 cm À1 was assigned to N-C-S ring stretching, C-C stretching, N-H, C-H or C-C rocking vibrations in different studies [28,40,52].…”
