Reversible movements of current polymeric actuators stem from the continuous response to signals from a controlling unit, and subsequently cannot be interrupted without stopping or eliminating the input trigger. Here, we present actuators based on cross-linked blends of two crystallizable polymers capable of pausing their movements in a defined manner upon continuous cyclic heating and cooling. This noncontinuous actuation can be adjusted by varying the applied heating and cooling rates. The feasibility of these devices for technological applications was shown in a 140 cycle experiment of free-standing noncontinuous shape shifts, as well as by various demonstrators.

非连续响应聚合物致动器

当前的聚合物致动器的可逆运动源于对来自控制单元的信号的持续响应，并且随后在不停止或消除输入触发器的情况下就不能被中断。在此，我们介绍了基于两种可结晶聚合物的交联共混物的促动器，该聚合物在连续循环加热和冷却时能够以定义的方式暂停其运动。这种不连续的致动可以通过改变所施加的加热和冷却速率来调节。这些设备在技术上的可行性在独立的非连续形状变化的140个周期的实验中以及各种示威者中得到了证明。
