Title: Characterizing the Mechanical Properties and Degradation of Thin Polymer Membranes
Published: August 28, 2011
Abstract: The elasticity, strength, and toughness of thin polymer membranes are of considerable interest since direct knowledge of these key mechanical properties can provide insight into performance, durability, and underlying degradation mechanisms that occur over a membrane‰s operational lifetime. However, there is a considerable lack of knowledge about these key mechanical properties due to the lack of appropriate measurement tools at the nanometer scale. Hence, research has focused on direct performance measurements aided by chemical and structural analysis, such as spectroscopy and scattering techniques. In this work, we utilize the phenomena of wrinkling and cracking as a tool for measuring the modulus, fracture strength, and onset fracture strain of ultrathin polymer membranes .
