Polyaniline films were successfully synthesized in this study using an oxidative polymerization method at temperatures ranging from 0 to 4 ° C. Polyaniline films were deposited using a single step of chemical oxidative polymerization rather than electrochemical polymerization. The polyaniline was examined using FTIR, XRD, SEM, AFM, and Four Point Probe. This result demonstrates that polyaniline synthesized using this method has a uniform morphology, small size (17 to 40) nm, high crystallinity, and high conductivity (9.42 s/cm).

In this study, we present a facile approach for the green synthesis of polyaniline (PANI) through electrochemical polymerization on a graphitic paste electrode, thus enhancing its use in electrochemical sensing applications. The morphology of the synthesized PANI was observed using scanning electron microscopy (SEM), the crystallinity of the material was studied using XRD, and further functional groups were characterized by FT‐IR and UV spectroscopy. PANI, coated on the surface of a graphitic paste ‐modified electrode (P‐GPME) by controlled electrolysis, demonstrated notable electrocatalytic activity toward L‐cysteine (L‐cyst). The redox behavior of L‐cyst at the P‐GPME surface was investigated using cyclic voltammetry. The limit of detection (LOD) and limit of quantification (LOQ) were determined to be 2.4 × 10−6 and 1.21 × 10−5 mol L−1, respectively. These results highlight the potential of P‐GPME for selective and sensitive detection of L‐cyst. Furthermore, the designed electrode was effectively employed for the determination of L‐cyst in urine samples.

This study investigates potentiodynamic synthesis of polyaniline (PANI) using pencil graphite electrodes (PGEs), aiming to elucidate deposition mechanisms under simple experimental conditions. By exploring PANI electrosynthesis through electrochemical, spectroscopic, and computational approaches, valuable insights into the physicochemical aspects of aniline polymerization are gained. The proposed synthetic method was challenged for the development of a new molecularly imprinted polymer for chloramphenicol on the surface of PGEs to obtain an innovative impedimetric sensor. The sensing platform shows a linear response in the target concentration range between 0.1 and 17.5 nM, in aqueous solutions, with a limit of detection of 0.03 nM and a limit of quantification of 0.09 nM. The results obtained suggest that the synthesis method proposed provide a way to obtain stable and electroactive polyaniline film with huge potential application.
