Abstract

We demonstrate that thermal wrinkling can be utilized to measure the rubbery modulus and shear viscosity of polystyrene (PS) thin films as a function of temperature. Specifically, we use surface laser-light scattering (SLS) to characterize the wrinkled surface in real-time in order to monitor the changes in morphology as a function of annealing time at fixed annealing temperatures. The results from such experiments are compared to a theoretical model,11 from which the viscoelastic properties of the PS thin film are extracted
