Abstract This study aims to determine the resonance parameters of polyaniline thin films to better understand the viscoelasticity properties of polyaniline films. The spin coating method was used with varying solvent concentrations and rotating speed of spin coater during the deposition Polyaniline (PANI) thin film on a quartz crystal microbalance (QCM). To determine the resonance parameters of the PANI thin film, the impedance and QCM frequency measurements were first carried out before and after coated with PANI. The modelling used is a modified BVD model, and the determined resonance parameters are C0, C1, L1, R1, L2 and R2. From the results of the analysis using the GRG Nonlinear solver program, it was found that solution concentration and rotational speed in the spin coating process has a significant effect on resonator parameters of PANI thin film. The best solution concentration from this study was 2% DMF with a rotational speed of 2,000 rpm. This is because in these conditions it provides a minimal damping effect on QCM.
