Abstract: A conductive flexible transparent wood film-based electronic device and its preparation method are provided. The preparation method is to remove most lignin and part hemicellulose from natural wood chips to prepare a transparent wood film, and a CNT/TOCNFs ink is printed on a surface of the transparent wood film to form a circuit. The as-prepared transparent wood film has high mechanical properties, flexibility, and excellent optical strength. The conductive flexible transparent wood film is fabricated by depositing the CNT/TOCNFs ink on the surface of the transparent wood film to form conductive circuits, which is combined with origami and kirigami to realize the editable and adjustable design of spatial structure. Thus, the shape of the flexible electronic devices changes from simple to complex, simultaneously, they are customized to meet specific needs or applications.

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.
