Abstract: An experimental method for reproducible results has been used to investigate dewetting behavior of thin film of mixed-solvent-laden polymer. The variation of the mixed solvent (acetone and water) in the composition enables the films to exhibit different dewetting behavior, such as the process of holes growth, from the unstable growth process to the stable growth process, the mechanism of holes growth, from the nucleation growth to the replacement of solvent, and the dewetting dynamics.

Key words: Thin polymer film, Mixed solvent, Solvent-induced dewetting
