PEDOT:PSS‐bacterial cellulose bilayer actuators: From the movement of ions to deflection

Abstract

Here, the role of the voltage waveform and the electrolytic ions in the actuation mechanism of Poly (3,4-ethylene dioxythiophene) polystyrene sulfonate (PEDOT: PSS)/bacterial cellulose bilayer actuator is reported. PEDOT:PSS/bacterial cellulosebased bilayer actuator was fabricated, and its mechanism under a square and triangular wave potential at multiple frequencies was studied. The actuation was performed with HCL, KCl, and LiCl electrolytes. The deflection of the actuator was found to be dependent on the time period of the voltage waveform. The deflection for opposite biases showed frequency-dependent asymmetry. Further, the actuator deflection was found to be related to the hydrodynamic size of cations present in electrolytes.The results indicate a cation-dominated actuation mechanism for PEDOT:PSS/bacterial cellulose bi-layer actuator.

Cellulose-Based Intelligent Responsive Materials: A Review

“…Among them, poly (3,4-ethylenedioxythiophene) (PEDOT) is considered as a very useful CP due to its conductivity, stability, and processability [98]. In order to investigate the actuation mechanism of electric-responsive actuators, Chalil et al [99] prepared a poly (3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS)/bacterial cellulose bilayer actuator. The electric response was performed using HCL, KCl, and LiCl electrolytes.…”
