Polyaniline coating on tin coated sheets

Q. Can polyaniline coating be used on tincoated steel sheets used for manufacturing cans?

A. Polyaniline is one of the first "conducting polymers" to be discovered. It can be electrodeposited onto tinplate, but my first question would be "why?". It is expensive and although it can be used to inhibit corrosion of tinplate, there are much cheaper systems. Perhaps the originator would like to expand on his/her needs and reasons?
