A process for fabricating an electronic device on a non-conductive polymer substrate, particularly from the family of polyaniline, comprises applying a covalent doping agent, such as an R.sup.+ donor compound, where R is an organic group, e.g., methyl iodide, to a preselected portion of a base-type non-conductive polymer substrate containing carbon-nitrogen linkages, and converting such preselected portion of the polymer substrate to an electrically conductive polymer portion, by covalent linkage of the R groups of such donor compound, to nitrogen atoms of the non-conductive polymer substrate. Electronic devices, such as resistors, capacitors, inductors, printed circuits and the like, can be provided by the invention process, in the form of light-weight polymers containing no metal, and which are stable and wherein the conductive portions are non-diffusing.
A process for producing an electronic device on a non-conductive polymer substrate which comprises applying a covalent doping agent to a preselected portion of a base-type non-conductive polymer substrate containing carbon-nitrogen linkages, said agent being capable of covalently binding to the nitrogens of said polymer, said covalent doping agent being an R.sup.+ donor compound containing an organic cation group, the R.sup.+ donor compound being selected from the group consisting of RX, R.sub.3 OX, R.sub.2 SO.sub.4, R'SO.sub.2 Cl, and R".sub.3 SiCl, where R, R' and R" are each selected from the group consisting of alkyl and aryl, and X is selected from the group consisting of halogen, PF.sub.6.sup.-, SbCl.sub.6.sup.- and benzene sulfonate, and wherein the base-type non-conductive polymer substrate is selected from the group consisting of polyaniline, its naphthyl and biphenyl derivatives, and alkyl and aryl substituted polyaniline and its alkyl and aryl substituted naphthyl and biphenyl derivatives, and converting said preselected portion of said polymer substrate to an electrically conductive polymer portion in which such cation groups are covalently linked to the nitrogen atoms of said preselected polymer portion.
