520	3		_aThe not-sufficient-enough conductance of semioxidized protonated polyaniline (PANI)is usually attributed to the presence of ordered quasi-metallic domains surrounded by a poorly conducting amorphous phase. The paper presents experimental results testifying to the existence, in semioxidized PANI, of multilevel redox heterogeneity that crucially effects the conductance magnitude in view of specific topology at which higher-oxidized (conducting)domains are surrounded by less oxidized (poorly conducting)domains and because the PANI conduction is extremely sensitive to the oxidation degree. It is shown experimentally that the interphase doping with metals and degenerate semiconductors of a semioxidized salt of PANI and poly(2-acrylamide- 2-methyl-1-propanesulfonic acid)(PAMPSA)with a 1 : 2 ratio between PANI and PAMPSA raises the PANI-PAMPSA conductivity by 3-8 orders of magnitude due to the formation near the interface of thin layers whose conductance depends on the work function of the material in contact with PANI-PAMPSA and in extreme cases substantially exceeds the conductance of gold and copper at room temperature.
