Abstract The experiment adheres to the principles of resource efficiency and environmental friendliness in science communication.It focuses on the preparation and application of silver nanowater-based conductive ink.By comparing the reaction effects of seven common reducing agents,the study ultimately selects ascorbic acid as the optimal reductant for the synthesis of silver nanoparticles with silver nitrate.This method is simple to operate,mild in reaction conditions,low in cost,produces uniform particles,and is environmentally friendly,fully meeting the practical requirements of science communication experiments.Using common photo paper from daily life,the experiment offers a“draw to create circuits”science experience,introducing cutting-edge nanomaterials and flexible electronics technologies in a safe,engaging,and easy-to-perform way into science education.This science communication experiment not only enhances students’ hands-on and scientific innovation capabilities but also provides a replicable teaching mode for promoting nanotechnology,improving public scientific literacy,and stimulating scientific interest among youth.
