Two-dimensional (2D) conducting polymers are expected to offer emergent topological, structural, and physical properties, which has become the “holy grail” for the development of plastic electronics. Here, we report the assembly of a free-floating metallic polymer layer, consisting of poly(3,4-ethylenedioxythiophene) complexed with poly(styrenesulfonate) anions, directed by electrostatic recognition, amphiphilicity, and aromatic interactions. The obtained large-area crystalline nanosheets exhibit excellent environmental stability and mechanical robustness, meanwhile showing an electrical conductivity of 1216 S·cm^–1, the highest among the nanometer-thick conducting polymers. The kirigami-inspired freestanding polymer thermoelectrics, repeatedly stretching up to 200% strain, is demonstrated with high Seebeck coefficient with an optimized power factor of 95 μW m^–1 K^–2. The large-scale assembly and aqueous compatibility of 2D conducting polymers provide an exciting platform for integrating thermoelectricity into free-floating polymer nanostructures.

静电识别驱动组件带来的Kirigami启发式导电聚合物热电

二维（2D）导电聚合物有望提供新兴的拓扑，结构和物理特性，这已成为塑料电子学发展的“圣杯”。在这里，我们报告了一个自由浮动的金属聚合物层的组装，该层由通过静电识别，两亲性和芳香族相互作用指导的与聚（苯乙烯磺酸盐）阴离子络合的聚（3,4-乙撑二氧噻吩）组成。所获得的大面积晶体纳米片表现出出色的环境稳定性和机械强度，同时显示出1216 S·cm ^–1的电导率，是纳米级导电聚合物中最高的。受激折线启发的独立式聚合物热电学，可反复拉伸至200％应变，具有高塞贝克系数，其优化的功率因数为95μWm ^–1 K ^–2。二维导电聚合物的大规模组装和水相容性为将热电整合到自由漂浮的聚合物纳米结构中提供了令人兴奋的平台。
