导电聚合物,尤其是聚(3,4-乙二醇二苯乙烯)(PEDOT)及其与聚(苯乙烯磺酸苯乙烯)(PEDOT:PSS)的复合物,提供了一个有前途的材料平台,以发展柔软的执行器或人工肌肉。迄今为止,基于PEDOT的执行器可在仿生学,生物医学,智能纺织品,微型施工器和其他功能应用领域提供。与其他导电聚合物相比,PEDOT提供更高的电导率和化学稳定性,较低的密度和工作电压,并且PEDOT与PSS的分散进一步丰富了溶解度,可溶性,加工性和灵活性的性能,从而使它们在基于执行器的应用中具有优势。但是,基于PEDOT的材料制造的执行器仍处于起步阶段,许多未知数和挑战需要对其当前和未来的发展进行更全面的了解。这篇综述旨在提供对驱动机制,绩效评估标准,处理技术和配置以及材料开发和应用的最新进展的全面理解。最后,我们还详细阐述了改善和利用基于PEDOT的执行器的未来机会。
Conducting polymers, particularly poly(3,4-ethylenedioxythiophene) (PEDOT) and its complex with poly(styrene sulfonate) (PEDOT:PSS), provide a promising materials platform to develop soft actuators or artificial muscles. To date, PEDOT-based actuators are available in the field of bionics, biomedicine, smart textiles, microactuators, and other functional applications. Compared to other conducting polymers, PEDOT provides higher conductivity and chemical stability, lower density and operating voltages, and the dispersion of PEDOT with PSS further enriches performances in solubility, hydrophility, processability, and flexibility, making them advantageous in actuator-based applications. However, the actuators fabricated by PEDOT-based materials are still in their infancy, with many unknowns and challenges that require more comprehensive understanding for their current and future development. This review is aimed at providing a comprehensive understanding of the actuation mechanisms, performance evaluation criteria, processing technologies and configurations, and the most recent progress of materials development and applications. Lastly, we also elaborate on future opportunities for improving and exploiting PEDOT-based actuators.
