Effects of grain boundary adhesion and grain size on ductility of thin metal films on polymer substrates
نویسندگان
چکیده
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-supported metal films agrees well with the simulation results. 2008 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.

Nanostructured ZnO thin films were prepared by sol-gel dip coating technique. Zinc acetate and ammonium hydroxide were used as precursors and ethanol was as solvent. Ammonium hydroxide (NH4OH) solution was added drop-wise under vigorous stirring to obtain the sol-gel of different pH (varying from 6.9 to 7.2). ZnO thin films were obtained by dipping the glass substrates for few seconds and then ...
