Abstract

In the past several years there have been a number of advances in the understanding of the physics of polymer thin films. However, there still remains a wide range of opportunities to further this understanding through the development of measurement tools capable of probing the physical behavior of polymer films on the sub-micrometer size scale. Here we employ a laser-light, surface scattering technique to probe the early stages of the development of the wrinkle wavelength and amplitude of a polystyrene film capped with a thin layer of aluminum subjected to isothermal annealing. The initial stages of amplitude growth reflect the viscous response of the polymer film to the buckling instability, while the long-time amplitude behavior is related to the rubbery nature of the material and can reveal information about the relaxation behavior of the polymer chains in this confined geometry.
