The invention relates to a synthetic method of an electric response 4D printing material, relates to the field of printing and intelligent materials, and in particular relates to a synthetic method of an electric response 4D material. The synthetic method of the 4D printing material comprises the following steps: I, preparing plastics; II, preparing a conducting material; III, connecting the polylactic acid/polytetrafluoroethylene synthesized plastics and the conducting material onto a 3D printer, respectively feeding the polylactic acid/polytetrafluoroethylene synthesized plastics prepared in step II and the conducting material prepared in step III into two spray heads, starting the printer, automatically feeding the materials according to an input program, and obtaining the electric response 4D printing material. The synthetic method has the advantages of simple operation step, and excellent material performance; by utilizing the electro-deforming characteristic of the synthesized material, the technology can be widely applied to the fields such as human exoskeletons, artificial muscles and the like in the future.
