Enhance ment of Active Cor rosion Pro tection of epoxy coating via Com bination of Inhibitor-Loade d Halloysite Nanotu bes

Recent achievements in surfa ce science open a new avenue for f abrication of environmentally friendly corrosion inhibitors directly into the coati ng, providing release of the inhibiting comp ound and termination of the corrosio n propagation at already damaged corrosion defects. The m ain idea here is to develop nanoca psules, which can be sensitive to the external (e.g., mecha nical dama ge) or internal (e.g., pH or temperature changes) corrosion trigger [۱, ۲] . The presen t work repo rts the fabrication of ۵ types of na nocapsules b y using halloysite nano tubes for the finding of low-cost na nocapsules. The interactive properties of fabrica ted nanocap sules are st udied in ۰.۵ M NaCl solution. In addition, effect of developed nano capsules used in active protective coating is in vestigated.
