▎ 摘　　要

NOVELTY - Preparing visible Janus structure color soft robot driven by near infrared involves preparing carbon-based ethanol solution on gas-liquid interface by Maroninga effect self-assembling to generate carbon-based film, multiple transfer by lifting method to obtain multi-layer carbon-based thin film, dripping polymer solution to multi-layer carbon-based film and curing to obtain flexible carbon-based conductor, carrying out poly-dopamine coating treatment to flexible polymer side of flexible carbon-based conductor, dispersing colloidal particle solution on gas-liquid interface by tip guide method to self-assemble to generate two-dimensional photonic crystal array, depositing and transferring two-dimensional photonic crystal array to flexible polymer side of flexible carbon-based conductor;, drying and transferring product at room temperature to obtain visible Janus structure color soft robot driven by near infrared. USE - Method for preparing visual Janus structure color soft robot driven by near infrared. ADVANTAGE - The visible Janus structure color soft robot has layered structure, structure color responsiveness and photo-thermal conversion characteristic with multiple characteristics of near infrared driving and photoelectric sensing, free end presenting bending motion under near infrared irradiation, the corresponding structure color response and electrical sensing response, low cost, simple and convenient technique, and it can be repeatedly used.
