Nanomechanical Measurements of Polymeric Systems



Mark R. VanLandingham, Christopher C. White, Xiaohong Gu, Tinh Nguyen


Durability, in terms of service life, is often related to the failure due to service conditions of an unacceptable percentage of a product population. In many cases, this percentage is much less than 1 %, and thus the factors affecting early times-to-failure are of particular interest. For many industry-relevant polymer systems, including coatings and sealants, early times-to-failure can be linked to local chemical and physical degradation, including local changes in mechanical behavior. Further, the weak links in multi-component polymer systems are typically the interphase regions that form at the component interfaces. Development of techniques to characterize microscale and nanoscale mechanical properties thus is important for understanding degradation mechanisms and improving the durability of these materials. In this presentation, nanomechanical measurements of several polymer systems, including PMMA, various epoxy systems, PP, and several sealant materials, are discussed. Elastic and viscoelastic properties of these materials are characterized in some cases as a function of exposure to various weathering conditions, and in other cases as a function of distance from an interface.
