Abstract

Viscoelastic behaviors of PI/SiO₂ nanocomposite films under constant and fatigue loads are experimentally studied. Creep strain, creep rate and creep compliance are determined. The effects of silica doping level, stress amplitude and loading pattern are discussed. Based on the experimental results, two viscoelastic models known as Burger model and Findley power law are employed to interpret the structure-property relations and deformation mechanisms of this kind of nanocomposite thin films.
