以不同平均粒径的琼脂颗粒为模板制备了多孔聚吡咯（PPy）膜。AP的大小可以通过制备过程中琼脂的浓度来调节，并且这些AP可以在通过电聚合形成膜后通过加热至90 °C而容易地从PPy膜中去除，因为琼脂显示出热可逆的溶胶-凝胶转变。PPy膜表面的孔可以通过模板AP的尺寸来控制。多孔聚吡咯薄膜具有更高的机械强度，并表现出更多的动态驱动行为比平面聚吡咯薄膜。此外，弹簧状致动运动是由螺旋形状的聚吡咯膜表面中的孔的存在引起的。
Porous poly(pyrrole) (PPy) films are prepared by utilizing agar particles (APs) of various average diameters as templates. The size of the APs can be regulated by the concentration of agar during preparation, and these APs can be removed easily from PPy films by heating up to 90 °C after formation of the films by electropolymerization because agar shows a thermally reversible sol–gel transition. The pores in the surface of PPy films can be controlled by the size of APs utilized as templates. The porous PPy films have higher mechanical strength and exhibit the more dynamic actuating behavior than the flat PPy films. Moreover, spring‐like actuating motion is induced by the presence of pores in the surface of helically shaped PPy films.
