Erbium oxide nanoparticles (Er 2 O 3 NP) were synthesized with an efficient method in the presence and absence of sodium dodecylsulfate (SDS) as surfactant. The effect of SDS on the morphology of the synthesized Er 2 O 3 NP is described. The NP were studied through scanning electron microscopy and X‐ray diffractometry. Then, polyaniline and a hybrid material of polyaniline/Er 2 O 3 NP were deposited directly on a stainless steel wire by the potentiostatic process. The electrochemical data and scanning electron microscopic studies of polyaniline and its nanocomposite on the stainless steel wire demonstrate the influence of the synthesized Er 2 O 3 NP on the electrodeposition of polyaniline. The presence of NP in the electrolyte solution during electrodeposition of polyaniline creates a nanocomposite with a more porous structure than pure polyaniline.
