Deformation Behaviors of Polymer Gels in Electric Field
A polymer gel is a crosslinked polymer network swollen in a liquid medium. Polymer gels, solid-liquid coexistent materials, are candidate biomimetic materials. Recently, their mechanical strength has become very close to that of living muscle. In a soft structure of gels, as shown in Fig. 1, the motion of polymer networks and the diffusion of ions take place easily by an external stimulus. The large volume or shape change, induced by supplying thermal, chemical or electrical energy, is an inherent nature of swollen gels.1‒4 Therefore, polymer gels have various possibilities as advanced functional polymers.
