Following the natural muscle antagonist actuation principle, different adaptations for "artificial muscles" are introduced in this work. Polypyrrole (PPy) films of different polymerization techniques (potentiostatic and galvanostatic) were analyzed and their established responses were combined in several ways, resulting in beneficial actuation modes. A consecutive "one-pot" electrosynthesis of two layers with the different deposition regimes resulted in an all-PPy bending hybrid actuator. While in most cases the mixed-ion activity of conductive polymers has been considered a problem or a drawback, here for the first time, the nearly equal expansions upon oxidation and reduction of carefully selected conditions further allowed to fabricate a "mirrored" trilayer laminate, which behaved as a linear actuator.
遵循天然肌肉拮抗肌驱动原理，本研究介绍了“人造肌肉”的不同适应性方法。分析了采用不同聚合技术（恒电位和恒电流）制备的聚吡咯（PPy）薄膜，并以多种方式组合其既定响应，从而产生有益的驱动模式。通过连续的“一锅法”电合成具有不同沉积方式的两层结构，得到了全PPy弯曲混合致动器。虽然在大多数情况下，导电聚合物的混合离子活性被认为是一个问题或缺点，但在此首次通过精心选择条件，使氧化和还原时的膨胀几乎相等，进一步实现了“镜像”三层叠层的制备，其表现为线性致动器。
