Abstract

This study aims to determine the effect of solvents on the viscoelastic properties and morphology of polyaniline thin films deposited on the surface of QCM using the spin coating method. The solvents used were NMP, m-cressol and DMF with varying concentrations of 1-4% by weight. The morphology of the polyaniline layer was observed via optical microscope and SEM/EDS. The observations show that the homogeneity of the polyaniline layer is still poor. There is an agglomeration of polyaniline powder which is insoluble in the solvent used. From the viscoelastic properties of the layer, the optimum value was obtained in samples with 2% NMP solvents.
