Abstract
AbstractStretchable conducting films are a prime necessity for future stretchable and wearable electronics. In this work, highly conducting poly(3,4 ethylenedioxythiophene):Tosylate (PEDOT:Tos) films are deposited on extremely stretchable styrene‐ethylene‐butylene‐styrene (SEBS) substrates via vapor phase polymerization (VPP) and their inherent properties are systematically studied. The charge transport and electrical properties of VPP PEDOT:Tos stretchable films are measured from room temperature down to the low temperature of 5 K. Interestingly, the mechanical properties of the stretchable substrate lead to buckling of the PEDOT:Tos that affect the electrical conductivity but not the charge carrier mobility, optical, and structural properties. The VPP PEDOT:Tos on the stretchable SEBS substrate show a semiconducting behavior as electrical resistance is enhanced upon cooling from room temperature to 5 K. Such kind of stretchable conducting films can be used for stretchable transistors, wearable sensing, energy storage, and electrochromic applications.
