Feasibility has been demonstrated for the use of the interpolymer complex of polyaniline with poly(2-acrylamide-2-methyl-1-propanesulfonic acid) (PAni center dot PAMPSA) and its nanocomposite with partially oxidized graphene (PAni center dot PAMPSA/POGr) as a material for hole transport layers in the manufacture of polymer light-emitting diodes (PLED). A study was carried out on the functional characteristics of such PLED, which were compared with those of traditional PLED made with poly(3,4-ethylenedioxythiophene) doped with polystyrenesulfonate anions (PEDOT/PSS). The PLED made with PAni center dot PAMPSA/POGr nanocomposites were shown to have better functional characteristics, namely, current density, brightness, current and luminous efficiency, than for the analogous heterostructures derived from the pure PAni center dot PAMPSA interpolymer complex. The PAni center dot PAMPSA/POGr nanocomposite may be used instead of PEDOT/PSS in the manufacture of efficient organic optoelectronic devices.
