The electro-induced shape-changing polymer materials (EISCP) are a kind of materials that have shapechanging response to electric stimulation. In other words
under the intermittent or continuous stimulation of an electric field or current
the shape of EISCP would make a specific shape-changing response. And when the electric field or current disappears
the shape tends towards recovery. EISCP have great potential applications in the field of artificial muscles
biomimetic robots
intelligent devices
drug carriers
etc. In this paper
according to the difference of the shape-changing response
the shape-changing mechanisms of electro-induced shape-changing polymer are divided into two types: electric field response type and current response type. And
the research progress and applications in electro-induced shapechanging polymer materials based on dielectric elastomers
ferroelectric polymers
electro-induced liquid crystal elastomers
electro-strictive graft elastomers
carbon nanotube composites
ionic polymer-metal composites
electroinduced shape-changing hydrogels
electro-shape memory polymers and conductive polymers were described in detail. Finally
the problems of electro-induced shape-changing polymer materials researches
such as low response speed
less deformation and shape-changing response highly dependent on "on/off" stimulation
are analyzed
and the future development of electro-induced shape-changing polymer materials are prospected.
