A compound (2), and a process to polarize it, are described able to form conductive or isolating tracks. The compound comprises a substrate of solvent, and a dispersion in the substrate. The dispersion comprises (i) a polymer (M) with double covalent conjugated bond, that is to say a heterocyclic compound formed of n atoms of carbon and an atom of a different type linked in a loop structure; and (ii) functionalising elements (Ql) of the polymer, so that the state of the polymer changes from insulator to conductor and vice versa when struck by an electromagnetic field. |
