Multi-functional epoxy composite coating incorporating mixed Cu(II) and Zr(IV) complexes of metformin and 2,2\-bipyridine as intensive network cross-linkers exhibiting anti-corrosion, self-healing and chemical-resistance performances for steel petroleum platforms

Metal-organic network cross-linking agents are commingled with epoxy for establishing multi-functional coating system with robust resistance properties for steel protection applications in harsh atmospheres. To support this concept, the present study relates to fabrication of new mixed ligand Cu(II) and Zr(IV) complexes of metformin (MF) and 2.2′bipyridine (bpy) as coating surface cross-linking modifiers to guard the steel surface of petroleum...
