National Physical Laboratories has technology for smart coatings of conducting polymers. These coatings can be used for prevention of corrosion of iron under hostile environmental conditions. You can paint railway bridges, sea-link bridges, ship hulls, undersea oil pipeline, TV and Microwave transmission towers, electricity poles, iron bars in concrete structures, undersurface of railway coaches and wagons, etc.
NPL says that the aim of the innovation was to design conducting polymer composites by incorporating filler materials and suitably selecting a medium for polymerization so that the resultant epoxy coatings can be used for prevention of corrosion of iron in saline water conditions.
It is different than conventional coatings in the following ways:
These coatings are conjugated polymers which have Smart action and have self healing ability: pin hole/scratch site passivation
They are environmental-friendly/based on green technology (free from heavy metal ions and hazardous chromates).
