Abstract
A process for producing an electrically driven mechanochemical actuator comprising: (a) immersing a mixture of poly(2-hydroxethyl methacrylate) and poly(methacrylic acid) crosslinked with 1,1,1-trimethylol propane trimethacrylate and ethylene glycol dimethacrylate into an aqueous polyelectrolyte solution to form a hydrogel; (b) applying an electrical field to the hydrogel sufficient to provide buckling, rippling, and contraction of the hydrogel; (c) terminating application of the electrical field and allowing the hydrogel to relax and return to its original shape; (d) reapplying the electrical field to the hydrogel sufficient to provide buckling, rippling, and contraction of the hydrogel.
