This work mainly studies the effect of calcium chloride crosslinking on the bending force properties of sodium alginate-based polymer gel paper actuators (PGPAs), where the driving layer is fabricated by the method of freeze-drying. The results indicate that the concentration of the crosslinking solution strongly affects the performance of the PGPAs and inappropriate concentration of crosslinking...
In this work, MCNT/MnO2 composite electrode actuators were fabricated by ultrasonic oscillating adsorption of MnO2 on both sides of the MCNT coated chitosan membrane. Elemental composition determined by an energy-dispersive spectrometer showed that the doping MnO2 was successfully adsorbed on the surface of MCNT. Surface morphologies of actuators under different doping MnO2 ratios (0, 0.1, 0.25, 0...
In this communication, we introduce a chitosan polymer gel ionic actuator with dilute acid as electrolyte solution replacing ionic liquid. Interestingly, the switch not only produces obvious improvements in actuation performance, but the actuator bends towards the opposite direction. It presents a cathode deflection phenomenon instead of the usual anode deflection. Moreover, ion channels inside the...
