An ABA triblock copolymer strategy for intrinsically stretchable semiconductors

Abstract

A novel semiconductor–rubber–semiconductor (P3HT–PMA–P3HT) triblock copolymer has been designed and prepared according to the principle of thermoplastic elastomers. It behaves as a thermoplastic elastomer with a Young's modulus (E) of 6 MPa for an elongation at break of 140% and exhibits good electrical properties with a carrier mobility of 9 × 10⁻⁴ cm² V⁻¹ s⁻¹. This novel semiconductor may play an important role in low-cost and large-area stretchable electronics.
