For my project I am looking for a material which can turn from being electrically conductive to nonconductive (has to be irreversible) upon exposure to electromagnetic radiation (say UV). I tried googling for my question but found no relevant answer. A short explanation or a link would be greatly appreciated.

  • $\begingroup$ I figure this is the case with most conducting polymers, especially if irradiation is performed in an oxygen environment. $\endgroup$ – Nicolau Saker Neto Feb 4 '16 at 20:33
