Abstract

We present a new measurement technique to quantify the viscoelastic properties of polymer thin films. This approach utilizes thermally-induced surface wrinkling to measure the rubbery modulus and shear viscosity of polymer thin films. Specifically, by applying a thermal stress to a polymer film that is capped with a metal thin film, we can infer the rubbery modulus and shear viscosity of the polymer film through the time-evolved wrinkle wavelength and amplitude. This technique can be extended to probe the viscoelastic properties of nanocomposite films as well as the effect of confinement on the ultrathin polymer films.
