Abstract
Segmented block copolymers (BCPs) of conjugated distyrylbenzene conjugated units linked by variable flexible nonconjugated units were p-doped, and their electrical conduction and Seebeck thermoelectric (TE) behaviors evaluated. The doped BCP Seebeck coefficients ranged up about 2600μVK−1, but with low conductivities giving low TE power factors. BCP blends with MEH-PPV gave much improved conductivity when doped with I2, and retained high enough Seebeck coefficients (up to about 530μVK−1) to give significantly higher TE power factors compared to the doped BCPs alone.
