ABSTRACT:
A process for the production of a conductive layer on a substrate, said conductive layer comprising a network of crystal needles of conductive radical cation salts based on tetrathiotetracenes, tetraselenotetracenes or tetratellurotetracenes and chlorine, bromine, iodine or copper dichloride, and said network is embedded in a polymer matrix, by coating at least one side of said substrate with a) a suspension of crystal needles of the radical cation salts of formula I in an inch solvent which may additionally contain a thermoplastic polymer or at least one starting compound for a thermosetting polymer, or b) a solution (b1) of a tetrathiotetracene, tetraselenotetracene or tetratellurotetracene, (b2) of a monomeric, oligomeric or polymeric organic compound which contains chlorine, bromine or iodone and, when heated with these tetracenes, forms a radical cation salt, or of anhydrous CuCl.sub.2, a CuCl.sub.2 aquo complex or a CuCl.sub.2 solvent complex, and (C3) of a thermoplastic polymer or at least one starting compound for a thermosetting polymer, in an inert solvent, and subsequently evaporating the solvent, which process comprises applying said layer by spraying the suspension a) or solution b) from nozzles on to the substrate. Very fine meshed, dense and isotropic crystal needle networks are obtained. The coatings exhibit rapid surface discharges and are suitable for use as electostatic coatings or, on account of their good electrical conductivities, as electrode material for display elements.
