Deformable Electronics: Conducting Polymer Dough for Deformable Electronics (Adv. Mater. 22/2016).
A simple strategy for changing a brittle conducting polymer (
PSS) into a solution-processed highly deformable viscoelastic polymer is presented by H.-K. Baik, U. Jeong, and co-workers on page 4455. The storage modulus versus loss modulus of the polymer is adjusted to control the viscoelastic properties to fit the properties required in deformable electronics. Rapid self-healing of conductivity, custom-designed LEDs with complex micropatterns, and foldable stretchable LEDs are demonstrated.
