Effects of grain boundary adhesion and grain size on ductility of thin metal films on polymer substrates

We have studied the effects of grain boundary adhesion and grain size on the ductility of thin metal films well bonded to polymer substrates, using a finite element method. It is shown that the ductility of polymer-supported metal films increases approximately linearly as the grain boundary adhesion increases, and as the grain size decreases. A rule-of-thumb estimate of the ductility of polymer...

Polymer elasticity-driven wrinkling and coarsening in high temperature buckling of metal-capped polymer thin films.

We report the critical effects the deformational stress from the elastic nature of a confined polymer layer has during the relaxation process on the buckling of thin metal-polymer bilayer systems (less than 100 nm) even above the temperature at which the polymer is in the liquid flow region. In contrast with what is generally believed, the dispersion force does not play a significant role in th...

Dewetting of Thin Viscoelastic Polymer Films on Slippery Substrates

Effect of Surface Properties on Wrinkling of Ultrathin Films

Thin films bonded to compliant substrates often develop wrinkles when subjected to an applied or inherent compressive stress. This paper presents a bilayer model to account for surface effects on the wrinkling of ultrathin solid films. Assuming a surface layer of finite thickness, effects of surface properties on the critical strain, the equilibrium wavelength, and the wrinkle amplitude are dis...
