为了实现一种新型的压电手性聚合物驱动器，我们研究了在交流电压作用下，聚L-乳酸（PLLA）薄膜的剪切压电性引起的运动。首先，对PLLA进行超临界CO2处理以改变其高阶结构，从而改善其压电性。然后，我们设计了一个PLLA薄膜卷传感器，它包括一个处理PLLA薄膜卷成一个长的薄卷。为了演示换能器，我们将其垂直放置在一个固定的支架上，在换能器的上端面放置一个塑料半球形容器。结果发现，当施加交流电压时，容器沿逆时针方向平稳地旋转。我们强调，本研究中没有使用特殊复杂的机械部件。
To realize a new piezoelectric chiral polymer actuator, we studied the motion induced by the shear piezoelectricity of a poly(L-lactic acid) (PLLA) film under the application of an ac voltage. First, PLLA was subjected to a supercritical CO2 treatment to change its high-order structure, resulting in an improvement in its piezoelectricity. Then, we designed a PLLA film roll transducer, which consisted of a piece of the treated PLLA film rolled into a long thin roll. To demonstrate the transducer, we placed it vertically on a fixed stand. A plastic hemispherical container was placed on the upper end face of the transducer. It was found that the container rotated smoothly in the counterclockwise direction when an ac voltage was applied. We emphasize that no special complex mechanical parts were used in this study.
