Abstract

A simple strategy for changing a brittle conducting polymer (

Pedot: 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.

Keywords: PEDOT:PSS; deformable devices; stretchable conducting polymers; stretchable electronics; viscoelasticity.
