Ultrasoft and High‐Mobility Block Copolymers for Skin‐Compatible Electronics
Abstract
<jats:title>Abstract</jats:title><jats:p>Polymer semiconductors (PSCs) are an essential component of organic field‐effect transistors (OFETs), but their potential for stretchable electronics is limited by their brittleness and failure susceptibility upon strain. Herein, a covalent connection of two state‐of‐the‐art polymers—semiconducting poly‐diketo‐pyrrolopyrrole‐thienothiophene (PDPP‐TT) and elastomeric poly(dimethylsiloxane) (PDMS)—in a single triblock copolymer (TBC) chain is reported, which enables high charge carrier mobility and low modulus in one system. Three TBCs containing up to 65 wt% PDMS were obtained, and the TBC with 65 wt% PDMS content exhibits mobilities up to 0.1 cm<jats:sup>2</jats:sup> V<jats:sup>−1</jats:sup> s<jats:sup>−1</jats:sup>, in the range of the fully conjugated reference polymer PDPP‐TT (0.7 cm<jats:sup>2</jats:sup> V<jats:sup>−1</jats:sup> s<jats:sup>−1</jats:sup>). The TBC is ultrasoft with a low elastic modulus (5 MPa) in the range of mammalian tissue. The TBC exhibits an excellent stretchability and extraordinary durability, fully maintaining the initial electric conductivity in a doped state after 1500 cycles to 50% strain.</jats:p>
