  4. Abstract:
  5. Smart coatings which prevent corrosion by several mechanisms recently have been carefully planned. One of these mechanisms is the use of ion exchangers like LDH in the coating network. Since the morphology is the most important properties for the applications that the surface plays an important role, LDH morphology was evaluated in this study. For this purpose, the LDH contain a kind of green inhibitor was synthesized and after evaluating its performance it was examined morphologically by changing significant parameters like MII/MIII, pH, aging time and temperature. It is found that, high ratio of the MII/MIII cause thinner layer of LDH. The pH also has special effect on the surface morphology. Approximately spherical grains will be formed in high pH. Rising the aging time and temperature also cause more growth and more atomic diffusions and result in uniform and intertwined grains. © 2017, Pleiades Publishing, Ltd
