Recently, many researches of block copolymer based soft electronic devices are reported including stretchable electrode, stretchable sensors and so on. Block copolymers that are physically cross-linked elastomer show unique advantages for examples, thermal, solution processiblity, 3D structure formability, etc. However, despite of this interest on block copolymer based devices, there are still undiscovered chapters on deformation behaviors of block copolymers. Though their nanoscale deformation behaviors are studied for decades, but behaviors over nanometer scales are not studied widely in spite of the increasing importance on device fabrication and performance at this scale. So, in this regard, we will present yielding behaviors of block copolymer over nanometer scale and also its correlation with nanometer phenomena utilizing digital image correlation(DIC) and various charaterization tools. |
