Improving the stretchability of as-deposited Ag coatings on poly-ethylene-terephthalate substrates

Submitted by Gi-Dong Sim on Thu, 12/13/2012 - 18:28

In this paper, we report that silver films evaporated on poly-ethylene-terephthalate (PET) substrates coated with an acrylic primer can be stretched beyond 70% without fracture. As-deposited films show a larger failure strain than annealed coatings. These observations are rationalized in light of a ductile fracture mechanism where debonding from the substrate coevolves with strain localization. The results of this study indicate that PET substrates coated with an acrylic primer layer may be suitable for stretchable electronics.

Journal Club Theme of December 2012: Metamaterials Inspired Concepts for Elastic Wave Energy Harvesting

Submitted by ruzzene on Tue, 12/11/2012 - 13:53

Recent journal club posts have illustrated the interesting and unique dynamic properties of phononic crystals and acoustic metamaterials (see April and May journal club entries by M. Hussein and A. Spadoni respectively). The ability of this class of engineered materials and structures to guide and focus elastic and sound waves can be exploited in a number of new applications and exciting functionalities.
