Nevertheless, their thermoelectric performance remains inferior to that of flexible inorganic materials, and scalable fabrication routes are scarce. To address these limitations, we developed irregular hierarchical-pore thermoelectric polymer (IHP-TEP) films by means of fine-tuned critical-transition phase separation. …
