Longitudinal size effects on electrical and actuation behaviors of ionic polymer-metal composite

Blog Article

The structural characteristics of ionic polymer-metal composite (IPMC) were analyzed, and the effects of IPMC length ranging from Gnomes 1 to 5 cm (with a width of 0.5 cm) were evaluated in terms of electrical parameters and actuation behavior.It has been concluded that the electrical parameters of IPMC materials (including capacitance, electrode resistance in thickness-direction, and internal resistance) decrease, and the bending strain of the setpoint increases as the length increases.

The simulation of the current response of IPMC to 2 V DC voltage shows that the error between Bath Additives simulated peak current using 1 cm-IPMC parameters and the measured value is 8.23 times higher than that of 5 cm-IPMC.The strain of the set point on 5 cm-IPMC sample is 5.

65 times bigger than that of the 1 cm-IPMC sample.
