With the increasing demands for novel flexible organic electronic devices, conductive polymers are now becoming the rising star for reaching such targets, which has witnessed significant breakthroughs in the fields of thermoelectric devices, solar cells, sensors, and hydrogels during the past decade due to their outstanding conductivity, solution-processing ability, as well as tailorability. However, the commercialization of those devices still lags markedly behind the corresponding research advances, arising from the not high enough performance and limited manufacturing techniques. The conductivity and micro/nano-structure of conductive polymer films are two critical factors for achieving high-performance microdevices. In this review, the state-of-the-art technologies for developing organic devices by using conductive polymers are comprehensively summarized, which will begin with a description of the commonly used synthesis methods and mechanisms for conductive polymers. Next, the current techniques for the fabrication of conductive polymer films will be proffered and discussed. Subsequently, approaches for tailoring the nanostructures and microstructures of conductive polymer films are summarized and discussed. Then, the applications of micro/nano-fabricated conductive films-based devices in various fields are given and the role of the micro/nano-structures on the device performances is highlighted. Finally, the perspectives on future directions in this exciting field are presented.
随着对新型柔性有机电子器件需求的不断增加，导电聚合物正成为实现这些目标的后起之秀。在过去十年中，由于其出色的导电性、溶液加工能力以及可定制性，导电聚合物在热电装置、太阳能电池、传感器和水凝胶等领域取得了重大突破。然而，这些器件的商业化仍明显落后于相应的研究进展，原因在于其性能不够高以及制造技术有限。导电聚合物薄膜的导电性和微/纳米结构是实现高性能微器件的两个关键因素。在这篇综述中，全面总结了利用导电聚合物开发有机器件的最新技术，首先将描述导电聚合物常用的合成方法和机理。接下来，将提供并讨论目前制备导电聚合物薄膜的技术。随后，总结并讨论了调整导电聚合物薄膜纳米结构和微观结构的方法。然后，给出了基于微/纳米制造导电薄膜的器件在各个领域的应用，并强调了微/纳米结构对器件性能的作用。最后，对这一令人兴奋的领域的未来发展方向进行了展望。
