Foldable Electronics: Foldable Electrochromics Enabled by Nanopaper Transfer Method (Adv. Funct. Mater. 27/2015)

A facile nanopaper transfer strategy is developed on page 4203 by P. S. Lee and co-workers for foldable transparent conductors of high quality. Electrochromic nanopaper that maintains a stable performance under repeated folding is demonstrated. The exceptional surface properties of nanocellulose endow a stable cycling and efficient coloration with the electrochromic device. The nanopaper transfer technique creates new opportunities for the next generation deformable electronics.
