A photothermally foldable soft bimorph was prepared via the dry transfer of poly(3,4-ethylenedioxythiophene) (PEDOT) doped with tosylate onto a poly(dimethylsiloxane) film. The photothermal folding was optimized via reversible actuation by controlling the thickness of each layer and the temperature increase to afford large deflection and displacement up to 150° and >20 mm, respectively, upon exposure to near-infrared (NIR) light (808 nm). A two-dimensional array of the bimorph converted into complex three-dimensional architectures, such as a Venus flytrap, under light and reversibly unfolded in the dark. Taking advantage of the photothermal nature of PEDOT, a localized heat pocket was generated inside the folding structure. Thus, a Venus flytrap with a hot pocket reaching 100 °C was realized for the first time. The Venus flytrap could trap and move an object within a few seconds of NIR exposure.

通过将掺有甲苯磺酸酯的聚（3,4-乙撑二氧噻吩）（PEDOT）干燥转移到聚（二甲基硅氧烷）薄膜上，制备出可光热折叠的软双晶型物。通过控制每一层的厚度和温度升高，通过可逆驱动来优化光热折叠，从而在暴露于近红外（NIR）光（808 nm）时分别提供高达150°和大于20 mm的大偏转和位移。 。双压电晶片的二维阵列在光照下转换为复杂的三维体系结构，例如维纳斯捕蝇器，并在黑暗中可逆地展开。利用PEDOT的光热特性，在折叠结构内部产生了局部热量囊。因此，首次实现了热袋达到100°C的维纳斯捕蝇器。
