Chinese Scientists Break Polymer Thermoelectric Record ZT Exceeds 1
A Chinese research team has innovatively developed polymer multi-heterojunction (PMHJ) thermoelectric materials, achieving a thermoelectric figure of merit (ZT) of 1.28 at 368 K, breaking the bottleneck of ZT > 1.0 for plastic-based thermoelectric materials. This study effectively reduces lattice thermal conductivity through interface structure and size effect control. The material also exhibits excellent flexibility and large-area fabrication capabilities, paving new avenues for energy supply in flexible electronic devices. This breakthrough promises significant advancements in the field of flexible and wearable electronics.
