Enhanced Electrical Performance and Stretchability by Plasticizer-Facilitated PEDOT:PSS Self-Alignment.

ABSTRACT: Stretchable, soft electronics have high potential for wearable healthcare applications and biointerfacing. One approach to render inherently brittle conductive polymers such as poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) stretchable are organic plasticizers. However, little is known on how they affect the morphology and in result the electrical properties of conductive thin-films. This study fundamentally explores this relationship using a bilayer model of transfer-printed PEDOT:PSS on stretchable, biocompatible poly(vinyl alcohol) substrates infused with glycerol (15-55 wt.%). The diffusion of the plasticizer leads to a reorganization of PEDOT and PSS, which is investigated using a multicomponent diffusion model. This approach correctly predicts the (plasticizer-de
