Re: Is there a polymer chain that can compact itself under an electric current?

I definitely do not think that there is a polymer chain that gets excited when electricity is passed through them. The reason is that the electricity cannot be conducted through polymers (they are insulators.) However there can be ferrous polymers that might react to magnetic forces. (You could research about this.) I am very sure that such an application might be very useful and that an ongoing research is in process(guessing).

I don't think that I'll be able to help you any further.
