We show that conductivity measurements on sandwiches of a polymer between normal-metal and superconducting-metal electrodes can be interpreted in terms of intrinsic superconductivity due to injection of charge into the polymer.

It is shown that the occurrence of metallic conductivity in polymers is due to their electrification. In particular, the current density depends on the electron work function of metallic electrodes which are in contact with the polymer.
