Abstract: Intelligent actuators have garnered significant attention for their applications in diverse fields such as soft robotics, artificial muscles, sensors, and intelligent skins. In this innovative experiment, we successfully synthesized a superhydrophobic actuation material by employing a layer-by-layer assembly approach, incorporating polyimide film (PI), polydimethylsiloxane (PDMS), and graphene. This material exhibits responsive behaviors to stimuli including light, electricity, and heat. Drawing inspiration from traditional Chinese paper-cutting techniques, we fashioned claw-shaped structures and deformable water collection devices, enabling intelligent programming even in challenging environments such as strong acids and alkalis. Serving as an effective educational tool, this experiment facilitates students’ understanding of fundamental scientific principles across multiple disciplines, spanning inorganic and polymer chemistry, instrumental analysis, and materials science, while emphasizing the seamless integration of theory and application. The selection of raw materials, which are non-toxic, cost-effective, and eco-friendly, aligns with the principles of green chemistry, underscoring the experiment’s sustainability. Notably, the experimental phenomenon is readily observable, and the operation process is engaging, fostering students’ enthusiasm for scientific research and innovation. This experiment offers a stimulating and enriching learning experience, nurturing students’ curiosity, and proficiency in scientific inquiry.
