Abstract
A flexible and smart wood with responsive function, an actuator and a preparation method of the flexible and smart wood with responsive function are provided. The preparation method includes the following steps: removing lignin from wood by using sodium chlorite solution, removing hemicellulose through alkali treatment, compounding a wood chip with an azobenzene compound by using a negative pressure method, and then densifying to form a wood film. According to the preparation method, the flexible and smart wood is successfully prepared, and the actuator made from the flexible and smart wood takes stimulation (such as illumination) given by an external environment as a power source, so that the actuator has an advantage of no secondary energy consumption.
