Abstract: The prospects of endowing stimuli-responsive materials with various life-likebehaviors are promoting the development of intelligent robotic and electronicdevices. However, it is challenging to incorporate stimuli-responsiveactuating and healing capabilities into one single material system. Herein, thedesign and assembly of humidity-responsive thin films composed of poly(3,4-ethylenedioxythiophene):polystyrene sulfonate (PEDOT:PSS) and sodiumcarboxymethyl cellulose (NaCMC) forming a conducting polymer compositethrough a physically cross-linked and hydrogen-bonded supramolecularnetwork are described. Owing to its enhanced dynamics of hydrogen bondingat an elevated humidity, the PEDOT:PSS/NaCMC thin film exhibits a rapidhumidity-responsive actuating performance in an environment with humiditygradient, as well as a repairing function of the structural, mechanical, electrical,and actuating properties after being damaged through a humidifying-dryingcycle. Based on a combined analytical approach, a structural model isproposed for the rearrangement of the thin film when being exposedto stepwise humidity levels at multi-length scales. Due to the structuralrearrangement powered by humidity variations, the film exhibits tunableactuating and healing performance, which makes it a promising candidatematerial for applications in intelligent soft robotics such as artificial muscles.
