摘要
In this current study, the electrophoretic deposition (EPD) process of polyaniline (PANI) is reported kinet-ically via the use of response surface methodology (RSM) with a focus on the three models of kinetics; Hamaker, Zhang, and Baldisseri using both statistical and quantitative techniques. The particles of formic acid and acetonitrile-based suspensions as a result of the electrostatic interaction were evaluated using particle size and zeta potential analyses. The fundamentals of PANI-EPD kinetics were used to demon-strate the influence of the EPD parameters on the properties of the deposited films over an interval of 180-600 s. The cathodic reduction during PANI-EPD simultaneously, the entanglement process and the control of the kinetics was once reported. Therefore, low voltages were used to avoid significant loss of PANI, which decreases during the EPD process, initiated by physicochemical characterization (SEM, FT-IR and XRD). The effect of deposition time and deposition voltage on PANI-EPD kinetics at intervals (180-600 s) was quantified by RSM. Accordingly, the result obtained obeyed a linear growth law consis-tent with Hamaker's' law. For comparison, optical absorbance and profilometry provide an approxima-tion of PANI's deposition rate, extinction coefficient, and density. Again, the Baldisseri model was able to reproduce experimental data well alongside some other semi-empirical equations of kinetics. The study is very significant in terms of the process through which thermal degradation occurs and as a result used this to anticipate the thermal stability of a process, thereby avoiding thermal degradation of poly-mer products as an industrial application.(c) 2022 The Korean Society of Industrial and Engineering Chemistry.
