“Triblock Copolymers- Using Nanophase Separation to Achieve Low Modulus, Elastic Deformation and Good Mobility in Polymer Semiconductors”
Polymer electronics are competitive for applications such as wearable sensors which require high mechanical functionality (e.g., elasticity), but only moderate electronic functionality (e.g., charge carrier mobility). Still, the elastic modulus of polymer semiconductors (PSCs) (0.1 – 1 GPa for typical PSCs) is orders of magnitudes away from human skin (0.1 – 10 MPa). Different pathways were explored to achieve low-modulus PSCs, e.g. non conjugated spacers [1], backbone regioregularity [2], or sidechains modifications [3], to name a few, but lowering the modulus is generally associated with a decrease in mobility.
